3. 应用功能详解

3.1. 功能一: 欢迎界面及版本更新检查(难)

1) 应用结构分析

在创建一个新的应用时,就需要对整个应用的包结构进行一个设计, 对应用包的组织大致有两种方法

l 方式一:按模块来组织代码的包结构,较大型的应用比较合适

办公软件

开会模块 com.atguigu.meeting

发工资模块 com.atguigu.money

出差模块 com.atguigu.travel

l 方式二: 按类型来组织代码的包结构, 中小型应用比较合适

手机卫士:

应用界面相关 com.atguigu.ms. activity|ui

显示列表的适配器 com.atguigu.ms.adapter

数据对象封装 com.atguigu.ms.bean|domain|entity

自定义视图 com.atguigu.ms.view|widget

复杂业务 com.atguigu.ms.engine

数据持久化 com.atguigu.ms.dao

广播接收者 com.atguigu.ms.receiver

后台服务 com.atguigu.ms.service

内容提供者 com.atguigu.ms.provider

2) 界面布局

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:id="@+id/ll_welcome_root"

android:layout_width="fill_parent"

android:layout_height="fill_parent"

android:orientation="vertical"

android:gravity="bottom|center_horizontal"

android:background="@drawable/logo">

<TextView

android:id="@+id/tv_welcome_version"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:text="版本号: 1.0"

android:textSize="20sp"

android:textColor="#000000"

android:layout_marginBottom="20dp"/>

<ProgressBar

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_marginBottom="50dp"/>

</LinearLayout>

3) 自定义旋转进度条

l 定义进度条的旋转动画,指定旋转的图片

<rotate xmlns:android="http://schemas.android.com/apk/res/android"

android:drawable="@drawable/progess"/> //注意此属性不能提示

l 引入定义的动画

android:indeterminateDrawable="@anim/anim_loding_progress" //进度动画

android:indeterminateDuration="700" //旋转一周持续的时间

4) 动画效果

AlphaAnimation animation =new AlphaAnimation(0.0f, 1.0f);

animation.setDuration(2000);

mLinearLayout.startAnimation(animation);

5) 获取应用的当前版本号

PackageManager packageManager =context.getPackageManager();

PackageInfo packageInfo = packageManager.getPackageInfo(context.getPackageName(), 0);

String version = packageInfo.versionName;

6) 将界面设置为无标题或全屏显示

l 动态编码的方式:

// 去掉窗口标题

requestWindowFeature(Window.FEATURE_NO_TITLE);

// 隐藏顶部的状态栏

getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);

setContentView();

l 配置方式:

//方式二(不建议使用)

android:theme="@android:style/Theme.Black.NoTitleBar"

android:theme="@android:style/Theme.Black.NoTitleBar.Fullscreen"

//方式三

</style>

7) 拷贝assert下的db文件到files

/**

* 把assets目录下的assert下的address.db拷贝到

* /data/data/com.atguigu.ms/files/

* @param dbname

private void copyDB(String dbname) {

File file = new File(getFilesDir(),dbname);

if(file.exists()&&file.length()>0){

Log.i (TAG, dbname+"数据库已经存在，不需要拷贝了...");

}else{

try {

InputStream is = getAssets().opendbname);

FileOutputStream fos = new FileOutputStream(file);

int len = 0;

byte buffer[] =new byte[1024];

while((len = is.read(buffer))!=-1){

fos.write(buffer, 0, len);

}

is.close();

fos.close();

} catch (IOException e) {

e.printStackTrace();

}

8) 应用版本更新检查流程

画图分析

9) 读取手机联网状态:

/**

* 检查当前网络是否可用

public static boolean isNetConnected (Context context) {

boolean connected = false;

// 获取手机所有连接管理对象（包括对wi-fi,net等连接的管理）

ConnectivityManager manager = (ConnectivityManager) context

.getSystemService(Context.CONNECTIVITY_SERVICE);

// 获取active的NetworkInfo对象

NetworkInfo networkInfo = manager.getActiveNetworkInfo();

if(networkInfo!=null) {

// 得到是否连接状态

connected = networkInfo.isConnected();

}

return connected;

}

10) 设计服务器端版本更新信息数据格式

l XML数据格式

<?xml version="1.0" encoding="UTF-8"?>

<apkUrl>http://192.168.173.1:8080/SecurityServer/Security.apk</apkUrl>

<desc>解决了上一个版本中的不少bug,优化了网络请求逻辑</desc>

</updateinfo>

l JSON数据格式

{

version:"1.1",

apkUrl:"http://192.168.173.1:8080/SecurityServer/Security.apk",

desc:"解决了上一个版本中的不少bug,优化了网络请求逻辑"

}

11) 联网请求远程服务器数据

//创建url地址对象

URL url =new URL(urlPath);

//打开连接

HttpURLConnection connection = (HttpURLConnection) url.openConnection();

//设置可以从服务器端读取返回的数据

connection.setDoInput(true);

//设置连接超时的时间

connection.setConnectTimeout(2000);//5000

//得到服务器端返回的数据流

InputStream is = connection.getInputStream();

12) 使用XmlPull解析xml文件

private UpdateInfo parseXml(InputStream is)throws Exception {

UpdateInfo info = new UpdateInfo();

XmlPullParser pullParser = XmlPullParserFactory.newInstance().newPullParser();

pullParser.setInput(is, "utf-8");

int eventType = pullParser.getEventType();

while (eventType != XmlPullParser.END_DOCUMENT) {

if (eventType == XmlPullParser.START_TAG) {

String tagName = pullParser.getName();

if ("version".equals(tagName)) {

info.setVersion(pullParser.nextText());

} else if ("apkUrl".equals(tagName)) {

info.setApkUrl(pullParser.nextText());

} else if ("desc".equals(tagName)) {

info.setDesc(pullParser.nextText());

}

eventType = pullParser.next();

}

return info;

}

13) 使用JsonObject解析json数据

private UpdateInfo parseJson(InputStream is)throws Exception {

//将数据流封装为json对象

String jsonString = Utils.readString(is);

JSONObject object = new JSONObject(jsonString);

//得到json对象中的数据封装为updateInfo对象

UpdateInfo info = new UpdateInfo();

info.setVersion(object.getString("version"));

info.setApkUrl(object.getString("apkUrl"));

info.setDesc(object.getString("desc"));

return info;

}

//使用Gson框架

UpdateInfo = new Gson().fromJson(jsonString, new TypeToken<UpdateInfo>(){}.getType())

14) 分线程网络请求后UI界面更新

//handler在主线程中处理分线程发过来的结果消息

private Handler handler =new Handler() {

public void handleMessage(android.os.Message msg) {

switch (msg.what) {

case REQUEST_UPDATE_ERROR:

break;

case REQUEST_UPDATE_SUCCESS:

break;

case REQUEST_APK_ERROR:

break;

case REQUEST_APK_SUCCESS:

break;

default:

break;

}

};

//启动分线程去请求服务器得到最新版本信息

new Thread(new Runnable() {

@Override

public void run() {

try {

info = APIClient.getUpdateInfo();

handler.sendEmptyMessage(REQUET_UPDATE_SUCCESS);

} catch (Exception e) {

e.printStackTrace();

handler.sendEmptyMessage(REQUEST_UPDATE_ERROR);

}

}).start();

15) 提示去下载和显示下载进度

/**

* 显示diaog,提示用户去下载

private void showDownloadDialog() {

new AlertDialog.Builder(this)ddd.setTitle("版本更新")

.setMessage("有更新的版本,是否立即下载更新?")

.setPositiveButton("下载",new DialogInterface.OnClickListener() {

@Override

public void onClick(DialogInterface dialog,int which) {

startDownloadApk();

}

}).setNegativeButton("取消",new DialogInterface.OnClickListener() {

@Override

public void onClick(DialogInterface dialog,int which) {

toMain();

}

}).show();

}

/**

* 开启分线程下载apk,并进行安装更新

private void startDownloadApk() {

//下载的url

final String apkUrl =info.getApkUrl();

//保存apk的本地file对象

createApkFile();

//显示下载进度的progressDialog

showDownloadProgress();

new Thread(new Runnable() {

@Override

public void run() {

try {

APIClient.downloadAPK(apkUrl,apkFile,pd);

handler.sendEmptyMessage(DOWNLOAD_APK_SUCCESS);

} catch (Exception e) {

e.printStackTrace();

handler.sendEmptyMessage(REQUEST_APK_ERROR);

}

}).start();

}

16) 将apk保存在sd卡中:

File sdFile = Environment.getExternalStorageDirectory();

apkFile = new File(sdFile,"update.apk");

/**或者**/

File filesDir = getExternalFilesDir(null);

apkFile = new File(filesDir,"update.apk");

17) 安装APK

Intent intent = new Intent();

intent.setAction(Intent.ACTION_VIEW);

intent.setDataAndType(Uri.fromFile(apkFile),"application/vnd.android.package-archive");

context.startActivity(intent);

18) 相关权限

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

<uses-permission android:name="android.permission.INTERNET" />

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

3.2. 功能二: 主界面的显示和功能项名称修改

1) 主界面的显示

private static final String[]NAMES =new String[] {

"手机防盗","通讯卫士","软件管理","流量管理","进程管理",

"手机杀毒","缓存清理","高级工具","设置中心" };

private static final int[]ICONS =new int[] { R.drawable.widget01,

R.drawable.widget02,R.drawable.widget03, R.drawable.widget04,

R.drawable.widget05, R.drawable.widget06,R.drawable.widget07,

R.drawable.widget08, R.drawable.widget09 };

<GridView

android:id="@+id/gv_main"

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:numColumns="3"

android:verticalSpacing="8dip">

</GridView>

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="80dp"

android:layout_height="80dp"

android:orientation="vertical"

android:gravity="center">

<ImageView

android:id="@+id/iv_item_main_icon"

android:layout_width="60dp"

android:layout_height="60dp"

android:src="@drawable/ic_launcher"

android:scaleType="fitXY"/>

android:layout_marginTop="2dp"

android:textColor="#000000"/>

</LinearLayout>

public View getView(int position, View convertView, ViewGroup parent) {

if (convertView ==null) {

convertView = inflater.inflate(R.layout.main_item,null);

}

ImageView imageView = (ImageView) convertView.findViewById(R.id.iv_item_main_icon);

TextView textView = (TextView) convertView.findViewById(R.id.tv_item_main_name);

imageView.setImageResource(ICONS[position]);

textView.setText(NAMES[position]);

return convertView;

}

2) 显示带输入框的Dialog

final EditText editText =new EditText(this);

editText.setHint("输入新的名称");

new AlertDialog.Builder(this)

.setView(editText)

.setTitle("名称修改")

.setPositiveButton("确定",new DialogInterface.OnClickListener() {

@Override

public void onClick(DialogInterface dialog,int which) {

}

}).setNegativeButton("取消",null).show();

3) 自定义名称的存储与读取

SharedPreferences preferences= getSharedPreferences("config", Context.MODE_PRIVATE);

//保存数据

Editor edit = preferences.edit().putString("lost_name", name).commit();

//读取数据

String lostName = preferences.getString("lost_name",null);

4) 显示进入手机防盗界面的Dialog

l 是否设置过密码的判断

通过SharedPreferences存储密码来实现

l 设置密码的布局

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="300dip"

android:background="#ffffff"

android:layout_height="wrap_content"

android:gravity="center_horizontal"

android:orientation="vertical" >

<TextView

android:hint="请输入密码"

android:inputType="textPassword" />

<EditText

android:id="@+id/et_pwd_set_confirm"

android:layout_width="280dip"

android:layout_height="wrap_content"

android:hint="请再次输入密码"

android:inputType="textPassword" />

<LinearLayout

android:layout_width="280dip"

android:layout_height="wrap_content"

android:gravity="center_horizontal"

android:orientation="horizontal">

android:layout_width="0dp"

android:layout_height="wrap_content"

android:layout_weight="1"

android:text="确定" />

<Button

android:id="@+id/btn_pwd_login_cancel"

android:layout_width="0dp"

android:layout_height="wrap_content"

android:layout_weight="1"

android:text="取消" />

</LinearLayout>

5) 自定义Button

l 9patch图片的制作

1) 指定patch区域(可复制区域)

2) 指定能显示内容的区域

l Selector多状态图片的配置

<item android:state_pressed="true" //此item必须在前面

android:drawable="@drawable/button_pressed"/>

</selector>

6) 连续点击回退键,才退出应用

l 监听back键的up事件

l 使用Handler进行延迟消息处理

private boolean exit =false;//只有它为true才退出

private Handlerhandler =new Handler(new Handler.Callback() {

@Override

public boolean handleMessage(Message msg) {

if(msg.what==1) {

Log.e("TAG","2s内没有再点back");

exit = false;//2s内没有再点back,下次点back不能退出

}

return false;

}

});

@Override

public boolean onKeyUp(int keyCode, KeyEvent event) {

if(keyCode==KeyEvent.KEYCODE_BACK) {

if(!exit) {

exit = true;//标识再点一次back就退出

handler.sendEmptyMessageDelayed(1, 2000);

return true;

} else {

handler.removeMessages(1);

}

return super.onKeyUp(keyCode, event);

}

7) 对密码进行MD5加密

l 对于应用中保存的密码,需要做加密处理再保存起来,这样就不至于将用户密码泄露

l 项目中用得最多的一种加密方式: MD5加密明文123456 密文

l MD5加密是将指定字符串加密为一个32位的字符串,是一个不可逆的操作

l 在线MD5解密是通过保存很多明文与密文的方式来实现解密的

1. 先将指定的字符串转换为一个16位的byte[]

2. 遍历取出数组中的每个byte元素

3. 将取出的byte值与255(0xff)做与运算(&)后得到一个255以内的数值

4. 将得到的数值转换为16进制的字符串,如果它只有一位,在它的前面补0

5. 将生成的16个二位16进制形式的字符串连接起来,它就是md5加密后的32位字符串

public static String md5(String pwd) {

StringBuffer sb = new StringBuffer();

try {

//创建用于加密的加密对象

MessageDigest digest = MessageDigest.getInstance("md5");

//将字符串转换为一个16位的byte[]

byte[] bytes = digest.digest(pwd.getBytes("utf-8"));

for(byte b : bytes) {//遍历

//与255(0xff)做与运算(&)后得到一个255以内的数值

int number = b & 255;//也可以& 0xff

//转化为16进制形式的字符串,不足2位前面补0

String numberString = Integer.toHexString(number);

if(numberString.length()==1) {

numberString = 0+numberString;

}

//连接成密文

sb.append(numberString);

}

} catch (Exception e) {

e.printStackTrace();

}

return sb.toString();

}

3.3. 功能三: 手机防盗与设置(难)

1) 设置流程

画图分析

2) 各个设置界面布局

l 关键技术点:< style>, <shape>, < RelativeLayout>, < LinearLayout>

l 布局文件

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"

android:layout_height="match_parent"

android:text="@string/guide1_item4"/>

<LinearLayout

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:layout_marginTop="8dip"

android:gravity="center_horizontal"

android:orientation="horizontal">

<ImageView

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:src="@android:drawable/presence_online"

android:contentDescription="@string/hello_world"/>

<ImageView

android:layout_width="wrap_content"

<ImageView

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:src="@android:drawable/presence_invisible"

android:contentDescription="@string/hello_world"/>

<ImageView

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:src="@android:drawable/presence_invisible"

android:contentDescription="@string/hello_world"/>

</LinearLayout>

<!—设置界面跳转的按钮 -->

<RelativeLayout

android:layout_width="match_parent"

android:layout_height="match_parent"

android:paddingBottom="5dp">

<Button

android:id="@+id/btn_guide_next"

android:text="@string/next"

style="@style/SetupGuideNext"/>

</RelativeLayout>

</LinearLayout>

l <style>的使用

<style name="SetupGuideItem">

<item name="android:layout_width">match_parent</item>

<item name="android:layout_height">wrap_content</item>

<item name="android:textSize">18sp</item>

<item name="android:drawableLeft">@android:drawable/btn_star_big_on</item>

<item name="android:layout_marginTop">8dip</item>

<item name="android:gravity">center_vertical</item>

</style>

<item name="android:layout_width">wrap_content</item>

<item name="android:layout_height">wrap_content</item>

<item name="android:drawableRight">@drawable/next</item>

</style>

<item name="android:layout_width">wrap_content</item>

<item name="android:layout_height">wrap_content</item>

<item name="android:drawableRight">@drawable/previous</item>

</style>

l <shap>的使用

<shape xmlns:android="http://schemas.android.com/apk/res/android"

android:shape="rectangle" >

<stroke

android:width="0.51dip"

android:color="#ffbc04e5" />

<gradient

android:startColor="#ffbc04e5"

android:centerColor="#ffc823ed"

android:endColor="#ffce30f2"/>

</shape>

3) 设置界面之间的跳转动画

l 关键技术: <translate>, overridePendingTransition()

<translate xmlns:android="http://schemas.android.com/apk/res/android"

android:fromXDelta="-100%p"

android:toXDelta="0"

android:duration="400" >

</translate>

//启用Activity切换动画

overridePendingTransition(R.anim.translate_right_in, R.anim.translate_left_out);

4) 绑定当前手机中的SIM卡

l 关键技术: TelephonyManager, SharedPreference, CheckBox

public static String getSimNumber(Context context) {

TelephonyManager telephonyManager =

(TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);

return telephonyManager.getSimSerialNumber();

}

5) 显示手机联系人列表:

l 关键技术: ContentResolver, Phone, Cursor, ListView, BaseAdapter, ProgressDialog, Handler, Thread

/**

* 得到所有联系人信息的集合

public List<ContactInfo> getContactInfos() {

List<ContactInfo> list = new ArrayList<ContactInfo>();

ContentResolver resolver =context.getContentResolver();

String[] projection = { Phone.DISPLAY_NAME, Phone.NUMBER };

Cursor cursor = resolver.query(Phone.CONTENT_URI, projection, null,null,null);

while (cursor.moveToNext()) {

String name = cursor.getString(0);

String number = cursor.getString(1);

list.add(new ContactInfo(name, number));

}

cursor.close();

return list;

}

6) 在设置页面得到选择的某个联系人号

l 关键技术: startActivityForResult(), onActivityResult(), setResult()

protected void onActivityResult(int requestCode,int resultCode, Intent data) {

if(requestCode==REQ_CONTACT_CODE && resultCode==2) {

//显示选择的手机号

String number = data.getStringExtra("number");

et_guide_phoneNumber.setText(number);

}

7) 开机检查SIM卡有没有更换

l 关键技术: 开机BroadcastReceiver及配置, SmsManager

public class BootCompleteReceiverextends BroadcastReceiver {

@Override

public void onReceive(Context context, Intent intent) {

// 条件1:启动了防盗监听

boolean isProtected = SpUtils.getInstance(context).getBoolean(SpUtils.IS_PROTECTED,false);

if (!isProtected)

return;

// 条件2:当前手机SIM号与保存的SIM号不一致

String currSimNumber = Utils.getSimNumber(context);

String simNumber = SpUtils.getInstance(context).getString(SpUtils.SIM,null);

if (simNumber !=null && simNumber.equals(currSimNumber))

return;

// 发送一个提示短信给保存的安全号

String number = SpUtils.getInstance(context).getString(SpUtils.NUMBER,null);

Log.e("TAG","number="+number);

if (!Utils.isEmpty(number)) {

SmsManager smsManager = SmsManager.getDefault();

smsManager.sendTextMessage(number, null,"SIM卡有变更,手机可能被盗了!",null,null);

}

<intent-filter>

</intent-filter>

</receiver>

8) 短信命令实现gps追踪,远程数据销毁,远程锁屏,远程报警功能

l 关键技术: 短信BroadcastReceivere及配置, LocationManager, DevicePolicyManager, MediaPlayer

l 读取接收到短信的BR类

public class SmsReceiverextends BroadcastReceiver {

@Override

public void onReceive(Context context, Intent intent) {

Bundle bundle = intent.getExtras();

Object[] pdus = (Object[]) bundle.get("pdus");

byte[] pdu = (byte[]) pdus[0];

SmsMessage smsMessage = SmsMessage.createFromPdu(pdu);

String phoneNumber = smsMessage.getOriginatingAddress();

String message = smsMessage.getMessageBody();

if ("#location#".equals(message)) {//gps追踪

abortBroadcast();

Log.e("TAG","回送位置信息!");

GpsUtils.sendLocation(context, safeNumber);

} else if ("#reset#".equals(message)) {// 远程销毁数据(恢复出厂模式)

abortBroadcast();

Log.e("TAG","远程销毁数据!");

Utils.resetPhone(context);

} else if ("#lock#".equals(message)) {// 远程锁屏

abortBroadcast();

Log.e("TAG","远程锁屏!");

Utils.lockScreen(context);

} else if ("#alarm#".equals(message)) {// 报警音乐

abortBroadcast();

Log.e("TAG","报警音乐!");

Utils.runAlarm(context, R.raw.jxmzf);

}

l 注册BR

<intent-filter android:priority="1000">

</intent-filter>

</receiver>

l 远程销毁数据

public static void resetPhone(Context context) {

DevicePolicyManager manager = (DevicePolicyManager)

context.getSystemService(Context.DEVICE_POLICY_SERVICE);

manager.wipeData(0);

}

l 远程锁屏

public static void lockScreen(Context context) {

DevicePolicyManager manager = (DevicePolicyManager)

context.getSystemService(Context.DEVICE_POLICY_SERVICE);

manager.resetPassword("23456", 0);//重新设置密码

manager.lockNow();//锁屏

}

l 警报音乐

public static void runAlarm(Context context, int resourceId) {

MediaPlayer mediaPlayer = MediaPlayer.create(context, resourceId);

mediaPlayer.setVolume(1.0f, 1.0f);//设置最大音量

mediaPlayer.start();

}

l GPS定位

n 三种定位方式:基于卫星(gps),基于网络(network),基于基站

n 基于卫星: 定位慢，准确度高，受环境影响大

北斗卫星导航系统（BDS）和美国GPS、俄罗斯GLONASS、欧盟GALILEO

n 基于网络:定位快，准确度低，受环境影响小, 但手机必须联网

n 基于基站:误差与基站数量与远近有关

public void sendLocation(Context context, String number) {

this.safeNumber = number;

lm = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);

// 判断GPS是否正常启动

if(!lm.isProviderEnabled(LocationManager.GPS_PROVIDER)) {

MSUtils.showMsg(context,"GPS没有开启");

return;

}

// 获取位置信息

Location location = lm.getLastKnownLocation(LocationManager.GPS_PROVIDER);

if(location!=null) {

double longitude = location.getLongitude();

double latitude = location.getLatitude();

String result = "经度: "+longitude+",纬度: "+latitude;

Log.e("TAG","发送经纬度: "+result);

SmsManager.getDefault().sendTextMessage(number,null, result,null,null);

}

// 绑定监听

// 参数1，设备：有GPS_PROVIDER和NETWORK_PROVIDER两种

// 参数2，位置信息更新周期，单位毫秒

// 参数3，位置变化最小距离：当位置距离变化超过此值时，将更新位置信息

// 参数4，监听

// 备注：参数2和3，如果参数3不为0，则以参数3为准；参数3为0，则通过时间来定时更新；两者为0，则随时刷新

lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 10000, 1,listener);

}

9) 激活应用的管理权限

l 关键技术: DevicePolicyManager, DeviceAdminReceiver, <receiver>

l 对于第三方应用, 如果需要做锁屏,恢复出厂设置等操作,需要提前先激活当前应用的对应管理权限

l Android 2.2 SDK提供了一个可管理和操作设备的API叫DevicePolicyManager，使用它可以接管手机的应用权限，对手机做出很多大胆的操作，比如锁屏、恢复出厂设置、设置密码、强制清除密码，修改密码、设置屏幕灯光渐暗时间间隔等操作。

l 在Manifest文件中定义配置

<receiver

android:name=".receiver.MyAdminReceiver"

android:permission="android.permission.BIND_DEVICE_ADMIN" >

<meta-data

android:name="android.app.device_admin"

android:resource="@xml/my_admin" />

<intent-filter>

</intent-filter>

</receiver>

l 定义设备管理权限配置(/xml/my_admin)

<device-admin xmlns:android="http://schemas.android.com/apk/res/android" >

<uses-policies>

<limit-password />

<watch-login />

<reset-password />

<force-lock /> <!—强制锁屏-->

<wipe-data />

<expire-password /> <!—使用密码失效-->

<encrypted-storage /> <!—对存储数据进行加密 -->

<disable-camera /> <!—使用相机失效-->

</uses-policies>

</device-admin>

l 定义设备管理的receiver

public class MyAdminReceiverextends DeviceAdminReceiver {

}

l 启动激活

public static void activeDevince(Context context) {

DevicePolicyManager manager = (DevicePolicyManager)

context.getSystemService(Context.DEVICE_POLICY_SERVICE);

ComponentName componentName = new ComponentName(context, MyAdminReceiver.class);

if (!manager.isAdminActive(componentName)) {

Intent intent = new Intent(DevicePolicyManager.ACTION_ADD_DEVICE_ADMIN);

intent.putExtra(DevicePolicyManager.EXTRA_DEVICE_ADMIN, componentName);

context.startActivityForResult(intent, 1);

}

判断是否激活

private boolean isActive() {

DevicePolicyManager manager = (DevicePolicyManager)

getSystemService(Context.DEVICE_POLICY_SERVICE);

ComponentName name = new ComponentName(this, DeviceAdminSampleReceiver.class);

return manager.isAdminActive(name);

}

10) 相关权限

<uses-permission android:name="android.permission.READ_PHONE_STATE" />

<uses-permission android:name="android.permission.READ_CONTACTS" />

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

<uses-permission android:name="android.permission.SEND_SMS" />

<uses-permission android:name="android.permission.RECEIVE_SMS" />

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

3.4. 功能四:手机归属地查询与来电显示

1) 查询手机归属地

l 关键技术: APIDemo动画效果, SQLiteDatabase,手机号正则表达式,手机号归属地规则

l 查询规则:

n 手机号:共11位数字, 第一个为: 1,第二位为: 3—8,前7位决定其归属地

n 匪警号码 : 3位

n 模拟器 : 4位

n 客服电话 : 5位

n 本地号码 : 6,7,8,9位

n 外地座机号:大于或等于10位, 以0开头,其第2,3位或2,3,4位决定其归属地

public static String getAddess(String number) {

String address = number;

SQLiteDatabase database = SQLiteDatabase.openDatabase(path,null,

SQLiteDatabase.OPEN_READONLY);

* 手机号:

* 1. 共11位数字

* 2. 第一个为: 1

* 3. 第二位为: 3--8

String reg = "^1[345678]\d{9}$";

if(number.matches(reg)) {

//手机号的归属地由其前7位来查询

String sql = "select location from data2 where id=(select outkey from data1 where id=?)";

Cursor cursor = database.rawQuery(sql,

new String[]{number.substring(0, 7)});

if(cursor.moveToNext()) {

number = cursor.getString(0);

} else {

address = "未知地区手机号";

}

cursor.close();

} else {

switch (number.length()) {

case 3:// 110,119,120

address = "匪警号码";

break;

case 4:// 5554,5556

address = "模拟器";

break;

case 5:// 10086,10010

address = "客服电话";

break;

case 6:

case 7:

case 8:

case 9:

address = "本地号码";

break;

default://外地座机号

if(number.startsWith("0") && number.length()>9) {

String sql = "select location from data2 where area =?";

Cursor cursor = database.rawQuery(sql,

new String[]{number.substring(1, 3)});

if(cursor.moveToNext()) {

String location = cursor.getString(0);

address = location.substring(0, location.length()-2);

break;

}

cursor = database.rawQuery("select location from data2 where area =?",

new String[]{number.substring(1, 4)});

if(cursor.moveToNext()) {

String location = cursor.getString(0);

address = location.substring(0, location.length()-2);

break;

}

cursor.close();

}

break;

}

return address;

}

2) 设置显示风格

关键技术: AlertDialog, SharedPreference

private void setStyle() {

String[] items = {"半透明","活力橙","苹果绿","孔雀蓝","金属灰"};

new AlertDialog.Builder(this)

.setTitle("选择颜色")

.setSingleChoiceItems(items, 0,new DialogInterface.OnClickListener() {

@Override

public void onClick(DialogInterface dialog,int which) {

SpUtils.getInstance(AToolActivity.this)

.putInt(SpUtils.BG_COLOR_INDEX, which);

}

})

.setPositiveButton(android.R.string.ok,null)

.show();

}

3) 设置显示的位置

关键技术: TouchEvent,LayoutParams, SharedPreference

iv_drag_location.setOnTouchListener(this);

@Override

public boolean onTouch(View v, MotionEvent event) {

switch (event.getAction()) {

case MotionEvent.ACTION_DOWN:

firstX = (int) event.getRawX();

firstY = (int) event.getRawY();

break;

case MotionEvent.ACTION_MOVE:

int moveX = (int) event.getRawX();

int moveY = (int) event.getRawY();

int distanceX = moveX -firstX;

int distanceY = moveY -firstY;

int newLeft =iv_drag_location.getLeft() + distanceX;

int newTop =iv_drag_location.getTop() + distanceY;

int newRight =iv_drag_location.getRight() + distanceX;

int newBottom =iv_drag_location.getBottom() + distanceY;

iv_drag_location.layout(newLeft, newTop, newRight, newBottom);

firstX = moveX;

firstY = moveY;

break;

case MotionEvent.ACTION_UP:

int x =iv_drag_location.getLeft();

int y =iv_drag_location.getTop();

SpUtils.getInstance(this).putInt(SpUtils.LOCATION_X, x);

SpUtils.getInstance(this).putInt(SpUtils.LOCATION_Y, y);

break;

default:

break;

}

return true;

}

4) 来电显示归属地

关键技术: Service,TelephonyManager, WindowManager,LayoutParams

windowManager = (WindowManager) getSystemService(Context.WINDOW_SERVICE);

telephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);

// Listen for changes to the device call state. 监听电话状态

telephonyManager.listen(listener, PhoneStateListener.LISTEN_CALL_STATE);

private PhoneStateListenerlistener =new PhoneStateListener() {

public void onCallStateChanged(int state, String incomingNumber) {

switch (state) {

case TelephonyManager.CALL_STATE_IDLE: //来电前或挂断电话后

removeAdressView();

break;

case TelephonyManager.CALL_STATE_RINGING: //响铃中

showAddress(incomingNumber);

break;

case TelephonyManager.CALL_STATE_OFFHOOK: //通话中

removeAdressView();

break;

default:

break;

}

};

WindowManager.LayoutParams params =new WindowManager.LayoutParams();

params.width = WindowManager.LayoutParams.WRAP_CONTENT;//宽度自适应

params.height = WindowManager.LayoutParams.WRAP_CONTENT;//高度自适应

params.format = PixelFormat.TRANSLUCENT;//设置成透明的

params.type = WindowManager.LayoutParams.TYPE_PHONE;//使addressView能移动

params.flags = WindowManager.LayoutParams. FLAG_NOT_FOCUSABLE; //使addressView不用获得焦点

// 根据设置的位置坐标定位

int x = SpUtils.getInstance(this).getInt(SpUtils.LOCATION_X, -1);

int y = SpUtils.getInstance(this).getInt(SpUtils.LOCATION_Y, -1);

if (x != -1) {

params.gravity = Gravity.LEFT | Gravity.TOP;

params.x = x;

params.y = y;

}

windowManager.addView(addressView, params);

<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />

判断服务是否已经开启

public static boolean isServiceRunning(Context context, String className) {

ActivityManager am = (ActivityManager)

context.getSystemService(Context.ACTIVITY_SERVICE);

List<RunningServiceInfo> runningServices =

am.getRunningServices(Integer.MAX_VALUE); //取出所有运行的

for(RunningServiceInfo info : runningServices) {

String serviceClassName = info.service.getClassName();

if(serviceClassName.equals(className)) {

return true;

}

return false;

}

3.5. 功能五: 通讯卫士

1) 黑名单管理

l 关键技术: SqliteOpenHelper, SqliteDataBase, Android单元测试, ListActivity, ArrayAdapter,

ContextMenu, AlertDialog

l Andorid单元测试的使用

<instrumentation android:name="android.test.InstrumentationTestRunner"

android:targetPackage="com.atguigu.my_ms" />

<uses-library android:name="android.test.runner" />

//单元测试类

public class BlackNumberDaoTestextends AndroidTestCase

l ContextMenu的使用

@Override

public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) {

menu.add(1, 1, 1, R.string.update_number);

menu.add(1, 2, 1, R.string.delete_number);

}

@Override

public boolean onContextItemSelected(MenuItem item) {

AdapterContextMenuInfo menuInfo = (AdapterContextMenuInfo) item.getMenuInfo();

int position = menuInfo.position;

switch (item.getItemId()) {

case 1:

showDeleteDialog(position);

break;

case 2:

dao.deleteNumber(numbers.get(position));

numbers.remove(position);

adapter.notifyDataSetChanged();

break;

default:

break;

}

return super.onContextItemSelected(item);

}

2) 黑名单来电与短信拦截

l 关键技术: Service, AIDL挂断电话,短信BroadcastReceiver, ContentResolver, ContentObersver

l 添加AIDL文件:

l 挂断电话

private void endCall() {//挂断电话

try {

// 通过反射拿到android.os.ServiceManager里面的getService这个方法的对象

Class clazz = Class.forName("android.os.ServiceManager");

Method method = clazz.getMethod("getService", String.class);

// 通过反射调用这个getService方法，然后拿到IBinder对象，然后就可以进行aidl啦

IBinder iBinder = (IBinder) method.invoke(null,

new Object[] { Context.TELEPHONY_SERVICE });

ITelephony telephony = ITelephony.Stub.asInterface(iBinder);

telephony.endCall();

} catch (Exception e) {

e.printStackTrace();

}

l 删除通话记录

l 直接删除通话记录不可行，因为生成通话记录的过程是一个异步的过程, 在挂断电话的瞬间, 通话记录表数据还没有执行添加, 只能通过Obersver来删除

private void deleteCallLog(final String number) {

final Uri uri = CallLog.Calls.CONTENT_URI;

getContentResolver().registerContentObserver(uri, true,

new ContentObserver(null) {

@Override

public void onChange(boolean selfChange) {

getContentResolver().delete(uri,

"number=?", new String[] { number });

getContentResolver().unregisterContentObserver(this);

}

);

}

<uses-permission android:name="android.permission.CALL_PHONE" />

<uses-permission android:name="android.permission.READ_CALL_LOG" />

<uses-permission android:name="android.permission.WRITE_CALL_LOG" />

3) 判断骚扰电话并显示通知

l 响铃时间不超过1s

l 不是联系人号

l 不是黑名单

private void showNotification(String incomingNumber) {

NotificationManager manager =

(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

Intent intent = new Intent(this, NumberSecurityActivity.class);

intent.putExtra("blackNumber", incomingNumber);

PendingIntent pi = PendingIntent.getActivity(this, 0, intent, 0);

Notification notification =new Notification.Builder(this)

.setContentTitle("发现响一声电话!")

.setContentText("点击添加"+incomingNumber+"为黑名单")

.setSmallIcon(R.drawable.logo)

.setContentIntent(pi)

.build();

manager.notify(0, notification );

}

<uses-permission android:name="android.permission.READ_CONTACTS" />

3.6. 功能六:软件管理

1) 应用的列表显示

l 关键技术: PackageManager, Map<Boolean, List<AppInfo>>, AsyncTask, BaseAdapter

public Map<Boolean, List<AppInfo>> getAllAppInfos()throws Exception {

Map<Boolean, List<AppInfo>> map =new HashMap<Boolean, List<AppInfo>>();

List<AppInfo> systemInfos = new ArrayList<AppInfo>();

map.put(true, systemInfos); //key是否是系统应用

List<AppInfo> customerInfos = new ArrayList<AppInfo>();//只存储非系统的第三方应用

map.put(false, customerInfos);

PackageManager packageManager =context.getPackageManager();

Intent intent = new Intent();

intent.setAction(Intent.ACTION_MAIN);

intent.addCategory(Intent.CATEGORY_LAUNCHER);

List<ResolveInfo> resolveInfos = packageManager.queryIntentActivities(intent, 0);

for (ResolveInfo ri : resolveInfos) {

String packageName = ri.activityInfo.packageName;

Drawable icon = ri.loadIcon(packageManager);

String appName = ri.loadLabel(packageManager).toString();

boolean isSystemApp =isSystemApp(packageManager, packageName);

AppInfo appInfo = new AppInfo(icon, appName, packageName, isSystemApp);

if (appInfo.isSystemApp()) {

systemInfos.add(appInfo);

} else {

userInfos.add(appInfo);

}

return map;

}

private boolean isSystemApp(PackageManager pm, String packageName) throws Exception {

PackageInfo packageInfo = pm.getPackageInfo(packageName, 0);

return (packageInfo.applicationInfo.flags & ApplicationInfo.FLAG_SYSTEM) > 0;

}

2) 应用的卸载,运行与分享

l 关键技术: PopupWindow, 分享/卸载/运行Intent

l 显示PopupWindow

popupView = View.inflate(this, R.layout.popup_view,null);

ll_app_uninstall = (LinearLayout)popupView.findViewById(R.id.ll_app_uninstall);

ll_app_uninstall.setOnClickListener(this);

ll_app_start = (LinearLayout)popupView.findViewById(R.id.ll_app_start);

ll_app_start.setOnClickListener(this);

ll_app_share = (LinearLayout)popupView.findViewById(R.id.ll_app_share);

ll_app_share.setOnClickListener(this);

popupWindow = new PopupWindow(popupView, 240, view.getHeight());

popupWindow.setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));

popupWindow.showAsDropDown(view, 50, 0 - view.getHeight());

Animation animation = new ScaleAnimation(0f, 1f, 0f, 1f);

animation.setDuration(500);

popupView.startAnimation(animation);

l 分享应用

private void shareApp(String appName) {

Intent intent = new Intent(Intent.ACTION_SEND);

intent.setType("text/plain");//纯文本

//intent.putExtra(Intent.EXTRA_SUBJECT,"应用分享");

intent.putExtra(Intent.EXTRA_TEXT,"分享一个不错的应用: " + appName);//内容

startActivity(intent);

}

l 根据包名启动应用

private void startApp(String packageName) {

PackageManager packageManager = getPackageManager();

Intent intent = packageManager.getLaunchIntentForPackage(packageName);

if (intent ==null) {

Utils.showToast(this,"此应用无法启动");

} else {

startActivity(intent);

}

l 根据包名卸载应用

private void uninStallApp(AppInfo appInfo) {

if (appInfo.isSystemApp()) {

Toast.makeText(this,"系统应用不能卸载!", 0).show();

} else if(getPackageName().equals(appInfo.getPackageName())) {

Toast.makeText(this,"当前应用不能卸载!", 0).show();

}else {

Intent intent = new Intent(Intent.ACTION_DELETE);

intent.setData(Uri.parse("package:" + appInfo.getPackageName()));

startActivity(intent);

}

l 监视应用的卸载

receiver = new UninstallReceiver();

IntentFilter filter = new IntentFilter(Intent.ACTION_PACKAGE_REMOVED);

filter.addDataScheme("package");// package:com.atguigu.ms

this.registerReceiver(receiver, filter);

private class UninstallReceiverextends BroadcastReceiver {

@Override

public void onReceive(Context context, Intent intent) {

String dataString =intent.getDataString(); //package:com.atguigu.ms

if(dataString!=null) {

AppInfo appInfo =new AppInfo();

appInfo.packageName = dataString.substring(dataString.indexOf(":")+1);

userInfos.remove(appInfo);

adapter.notifyDataSetChanged();

}

3.7. 功能七:程序锁(难)

1) 应用的列表显示, 加锁与解锁

l 关键技术: SqliteDatabase, ListView, BaseAdapter, TranslateAnimation

Service, ActivityManager

ContentProvider, ContentResolver,ContentObserver,

@Override

public void onItemClick(AdapterView<?> parent, View view,int position,long id) {

// 添加动画效果，动画结束后，就把锁的图片改变

TranslateAnimation animation =new TranslateAnimation(Animation.RELATIVE_TO_SELF,

0f,Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0f,

Animation.RELATIVE_TO_SELF, 0f);

animation.setDuration(500);

view.startAnimation(animation);//向右水平快速移动后复原

AppInfo appInfo = appInfoList.get(position);

ViewHolder viewHolder = (ViewHolder) view.getTag();

boolean lock = (Boolean) viewHolder.lockIV.getTag();

if (lock) {

viewHolder.lockIV.setImageResource(R.drawable.unlock);

viewHolder.lockIV.setTag(false);

lockedApps.remove(appInfo.getPackageName());

Uri uri = Uri.parse("content://com.atguigu.security.provider.applockprovider/delete");

getContentResolver().delete(uri,null,new String[] { appInfo.getPackageName() });

} else {

viewHolder.lockIV.setImageResource(R.drawable.lock);

viewHolder.lockIV.setTag(true);

lockedApps.add(appInfo.getPackageName());

ContentValues values = new ContentValues();

values.put("packagename", appInfo.getPackageName());

Uri uri = Uri.parse("content://com.atguigu.security.provider.applockprovider/insert");

getContentResolver().insert(uri, values);

}

2) 监听锁定应用的启动

l 关键技术: 流程分析ContentProvider, ContentResolver, ContentObsver, Service, Thread,ActivityManager

l AppLockMonitorService-----启动监听线程(一直运行)

n 获取最新启动的应用信息

n 判断它是否需要锁定

n 如果是, 启动解锁界面

n 适当的睡眠

/**

* 开启一直运行的子线程监听

private void startMonitor() {

new Thread(new Runnable() {

@Override

public void run() {

while (flag) {

// 1. 得到当前最近启动的应用packageName

String packageName = getCurrentPackageName();

Log.e("TAG","start pn=" + packageName);

try {

// 2. 判断是否需要锁定此应用

// 判断是否在临时不锁定的列表中,如果是不用显示解锁界面

// 如果在,启动一个锁屏界面(LockScreenActivity)

if (!tempUnlockNames.contains(packageName) &&

appLockNames.contains(packageName)) {

startLockScreenActivity(packageName);

}

Thread.sleep(100);

} catch (InterruptedException e) {

e.printStackTrace();

}

}).start();

}

private StringgetTopPackageName() {

return am.getRunningTasks(1).get(0).topActivity.getPackageName();

}

private void startLockScreenActivity(String packageName) {

Intent intent = new Intent(this, LockScreenActivity.class);

//intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);//必须是此flag

intent.putExtra("packagename", packageName);

startActivity(intent);

}

l AppLockProvider-----为应用锁表数据编写ContentProvider

@Override

public Uriinsert(Uri uri, ContentValues values) {

int match =matcher.match(uri);

if (match ==1) {

String packageName = values.getAsString("packagename");

appLockDao.add(packageName);

//通知所有监听在此URI上的obsever

getContext().getContentResolver().notifyChange(URI,null);

} else {

throw new RuntimeException("格式不正确");

}

return null;

}

@Override

public int delete(Uri uri, String selection, String[] selectionArgs) {

int match =matcher.match(uri);

if (match ==1) {

appLockDao.delete(selectionArgs[0]);

//通知所有监听在此URI上的obsever

getContext().getContentResolver().notifyChange(URI, null);

} else {

throw new RuntimeException("格式不正确");

}

return 0;

}

l AppLockActiviy-----通过ContentResolver向应用锁表中添加或删除记录

//删除数据

Uri uri = Uri.parse("content://com.atguigu.my_ms.provider.applockprovider/applock");

getContentResolver().delete(uri, null,new String[] { appInfo.getPackageName() });

//添加记录

ContentValues values = new ContentValues();

values.put("packagename", appInfo.getPackageName());

Uri uri = Uri.parse("content://com.atguigu.my_ms.provider.applockprovider/applock");

getContentResolver().insert(uri, values);

l AppLockMonitorService-----监听应用锁表数据的变化

Uri uri = Uri.parse("content://com.atguigu.security.provider.applockprovider");

getContentResolver().registerContentObserver(uri, true, observer);

protected ContentObserverobserver =new ContentObserver(new Handler()) {

public void onChange(boolean selfChange) {

appLockNames = appLockDao.getAll();

Log.e("TAG","ContentObserver onChange()..");

}

};

l LockScreenActivity ----密码验证与解锁通知

Intent service = new Intent(this, AppLockMonitorService.class);

service.putExtra("packageName",packageName);

startService(service );

3.8. 功能八: 进程管理

1) 显示系统和第三方应用进程列表

l 关键技术: PackageManager, ActivityManager,AsyncTask, ListView,

BaseAdapter, List<ProcessInfo>

l 得到所有正在运行的进程的信息

public static void getAllProcessInfos(Context context,

List<ProcessInfo> systemProcessInfos, List<ProcessInfo> userProcessInfos) {

ActivityManager am = (ActivityManager) context

.getSystemService(Context.ACTIVITY_SERVICE);

List<RunningAppProcessInfo> processInfos = am.getRunningAppProcesses();

PackageManager pm = context.getPackageManager();

for (RunningAppProcessInfo processInfo : processInfos) {

ProcessInfo info = new ProcessInfo();

// 包名

String packageName = processInfo.processName;

info.setPackageName(packageName);

// 应用占用的内存 bit/byte

MemoryInfo memoryInfo = am

.getProcessMemoryInfo(new int[] { processInfo.pid })[0];

long memInfoSize = memoryInfo.getTotalPrivateDirty() * 1024;

info.setMemInfoSize(memInfoSize);

try {

// 图标

Drawable icon = pm.getPackageInfo(packageName, 0).applicationInfo.loadIcon(pm);

info.setIcon(icon);

// 应用名称

String name = pm.getPackageInfo(packageName, 0).applicationInfo

.loadLabel(pm).toString();

info.setAppName(name);

// 是否是系统应用进程

int flag = pm.getPackageInfo(packageName, 0).applicationInfo.flags;

if ((flag & ApplicationInfo.FLAG_SYSTEM) == 0) {//用户进程

info.setSystem(false);

} else {//系统进程

info.setSystem(true);

}

} catch (NameNotFoundException e) {//根据包名得到不到PackageInfo

e.printStackTrace();

info.setIcon(context.getResources().getDrawable(R.drawable.icon));

info.setAppName(packageName);

info.setSystem(true);

}

//不同类型的Info保存到不同的集合中

if(info.isSystem()) {

systemProcessInfos.add(info);

} else {

userProcessInfos.add(info);

}

l 得到手机中可用内存大小

public static long getAvailMem(Context context) {

ActivityManager am = (ActivityManager) context

.getSystemService(Context.ACTIVITY_SERVICE);

ActivityManager.MemoryInfo outInfo = new ActivityManager.MemoryInfo();

am.getMemoryInfo(outInfo);

return outInfo.availMem;

}

l 得到手机中总内存大小

@TargetApi(Build.VERSION_CODES.JELLY_BEAN)

public static long getTotalMem(Context context) {

long totalMem = 0;

int sysVersion = VERSION.SDK_INT;//得到当前系统的版本号

// 下面的方式只能在JELLY_BEAN(16)及以上版本才有用

if (sysVersion >= Build.VERSION_CODES.JELLY_BEAN) {

ActivityManager am = (ActivityManager) context

.getSystemService(Context.ACTIVITY_SERVICE);

ActivityManager.MemoryInfo memoryInfo = new ActivityManager.MemoryInfo();

am.getMemoryInfo(memoryInfo);

totalMem = memoryInfo.totalMem;

} else {

try {//在版本小于16时,读取/proc/meminfo文件的第一行来获取总大小

File file = new File("/proc/meminfo");

FileInputStream fis = new FileInputStream(file);

BufferedReader reader = new BufferedReader(

new InputStreamReader(fis));

String result = reader.readLine();// MemTotal: 510484 kB

result = result.substring(result.indexOf(":") + 1,

result.indexOf("k")).trim();// 510484

reader.close();

totalMem = Integer.parseInt(result) * 1024;

} catch (Exception e) {

e.printStackTrace();

}

return totalMem;

}

l 文件大小格式化

//返回格式化后的大小:1.5GB,12MB,16.66KB, 0.00B 101010101byte

String Formatter.formatFileSize(context,byteSize);

2) 进程的清理

l 关键技术: ActivityManager

//根据包名杀死对应的进程

activityManager.killBackgroundProcesses(packageName)

<uses-permission android:name="android.permission.KILL_BACKGROUND_PROCESSES" />

3) 清理进程的widget

l 关键技术: AppWidgetProvider,<appwidget-provider>, RemoteView, Service,

PendingIntent, Handler

l AppWidgetProvider : 接收widget工具添加到桌面或从桌面移除等广播的receiver

public class ProcessWidgetextends AppWidgetProvider {

private Intentintent;

@Override

public void onEnabled(Context context) {//长按产生一个widget

intent = new Intent(context,UpdateWidgetService.class);

context.startService(intent);

}

@Override

public void onDeleted(Context context,int[] appWidgetIds) {//移除桌面的widget

if (intent !=null) {

context.stopService(intent);

intent = null;

}

l 注册receiver

<intent-filter>

<meta-data

android:name="android.appwidget.provider"

android:resource="@xml/process_widget" />

</receiver>

l 应用小工具的配置文件

<appwidget-provider

xmlns:android="http://schemas.android.com/apk/res/android"

android:initialLayout="@layout/process_widget"

android:minHeight="72dp"

android:minWidth="294dp">

</appwidget-provider>

l UpdatewidgetService 用于更新widget的服务

@Override

public void onCreate() {

super.onCreate();/*

//创建用于更新widget的管理器

manager = AppWidgetManager.getInstance(this);

//包含widget视图布局的远程视图对象

remoteViews = new RemoteViews(getPackageName(),

R.layout.process_widget_view);

//为widget中的button添加点击监听

Intent intent = new Intent(this,UpdatewidgetService.class);

intent.putExtra("clear",true);

PendingIntent pendingIntent = PendingIntent.getService(this, 0, intent,

0);

remoteViews.setOnClickPendingIntent(R.id.btn_widget_clear,

pendingIntent);

//准备用于更新widget的组件对象

componentName = new ComponentName(this, ProcessWidget.class);

//更新widget

updateWidget();

//发送延迟消息,使用widget能每隔2秒更新一次

handler.sendEmptyMessageDelayed(1, 2000);

}

private void updateWidget() {

MSUtils.log("updateWidget()...");

processCount = MSUtils.getProcessCount(this);//进程大小

remoteViews.setTextViewText(R.id.tv_widget_process_count,"进程数为 "

+ processCount);

availMem = MSUtils.getAvailMem(this);//可用内存大小

remoteViews.setTextViewText(R.id.tv_widget_process_memory,"可用内存为 "

+ Formatter.formatFileSize(this,availMem));

manager.updateAppWidget(componentName,remoteViews);

}

l 使用BroadcastReceiver使应用更省电

private ScreeenReceiverreceiver;

private void registScreenReceiver() {

receiver = new ScreeenReceiver();

IntentFilter filter = new IntentFilter();

filter.addAction(Intent.ACTION_SCREEN_ON); //开屏

filter.addAction(Intent.ACTION_SCREEN_OFF);//锁屏

registerReceiver(receiver, filter );

}

private class ScreeenReceiverextends BroadcastReceiver {

@Override

public void onReceive(Context context, Intent intent) {

String action = intent.getAction();

if(Intent.ACTION_SCREEN_ON.equals(action)) {

Log.e("TAG","开屏....");

handler.removeCallbacksAndMessages(null);

handler.sendEmptyMessage(1);

} else {

Log.e("TAG","锁屏....");

handler.removeCallbacksAndMessages(null);

}

l 为应用生成桌面快捷方式

private void createShortcut() {

//得到是否生成快捷图标的标识

boolean shortcut = SpUtils.getInstance(this)

.getBoolean(SpUtils.SHORT_CUT,false);

if(!shortcut) {

Intent intent = new Intent("com.android.launcher.action.INSTALL_SHORTCUT");

//图标

intent.putExtra(Intent.EXTRA_SHORTCUT_ICON,

BitmapFactory.decodeResource(getResources(), R.drawable.logo));

//名称

intent.putExtra(Intent.EXTRA_SHORTCUT_NAME,"手机卫士");

//点击快捷键,启动哪个界面

Intent callIntent = new Intent("com.atguigu.my_ms.action.Main");

intent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, callIntent);

//发送广播,桌面(laucher)应用有Receiver接收并生成桌面图标

sendBroadcast(intent);

//保存已生成快捷图标的标识

SpUtils.getInstance(this).put(SpUtils.SHORT_CUT,true);

}

<uses-permission android:name="com.android.launcher.permission.INSTALL_SHORTCUT" />

3.9. 功能九: 缓存清理

1) 得到应用的安装包,数据和缓存大小

关键技术: PackageManager, AIDL, 反射调用@hide的方法

l 得到应用的cache大小

//得到安装的所有应用

List<ApplicationInfo> applications = pm.getInstalledApplications(0);

//得到某个应用的缓存数据

Method method = PackageManager.class.getMethod("getPackageSizeInfo",

String.class, IPackageStatsObserver.class);

method.invoke(pm, packageName,new IPackageStatsObserver.Stub() {

@Override

public void onGetStatsCompleted(PackageStats pStats,boolean succeeded) {

long cacheSize = pStats.cacheSize);

}

});

l 权限: android.permission.GET_PACKAGE_SIZE

2) 清理缓存

l 通过反射+AIDL调用PackageManager的hide方法实现

l 只能是系统应用使用,第三方应用不能使用

Method method = PackageManager.class.getMethod("deleteApplicationCacheFiles",

String.class, IPackageDataObserver.class);

method.invoke(pm, info.packageName,new IPackageDataObserver.Stub(){

@Override

public void onRemoveCompleted(String packageName,

boolean succeeded)throws RemoteException {

}

}});

l 调用系统设置应用清理缓存

Intent intent = new Intent();

intent.setAction("android.settings.APPLICATION_DETAILS_SETTINGS");

intent.setData(Uri.parse("package:" +cacheInfos.get(position).getPackageName()));

startActivity(intent);

3.10. 功能十: 流量管理

1) 应用流量列表显示:

l 关键技术: SlidingDrawer, PackageManager, ApplicationInfo, TrafficStats

/**

* 得到应用的所有流量信息

public static List<TrafficInfo> getAllTrafficInfos(Context context) {

List<TrafficInfo> list = new ArrayList<TrafficInfo>();

PackageManager pm = context.getPackageManager();

//安装的所有应用(包含没有主界面的)

List<ApplicationInfo> infos = pm.getInstalledApplications(0);

for(ApplicationInfo info : infos) {

TrafficInfo trafficInfo = new TrafficInfo();

//appName

String appName = info.loadLabel(pm).toString();

trafficInfo.setName(appName);

//icon

Drawable icon = info.loadIcon(pm);

trafficInfo.setIcon(icon);

int uid = info.uid; //userID

//inSize 下载流量

long inSize =TrafficStats.getUidRxBytes(uid); //receive

trafficInfo.setInSize(inSize);

//outSize 上传流量

long outSize =TrafficStats.getUidTxBytes(uid);

trafficInfo.setOutSize(outSize);

list.add(trafficInfo);

}

return list; 7

}

//根据应用的id得到其下载流量和上传流量

long uidRxBytes =TrafficStats.getUidRxBytes(uid);

long uidTxBytes = TrafficStats.getUidTxBytes(uid);

//得到手机总的下载流量和上传流量(2g/3g/wifi)

long totalRxBytes = TrafficStats.getTotalRxBytes(); //receive

long totalTxBytes = TrafficStats.getTotalTxBytes();

//得到手机的下载流量和上传流量(2g/3g)

long mobileRxBytes = TrafficStats.getMobileRxBytes();

long mobileTxBytes = TrafficStats.getMobileTxBytes();

3.11. 功能十一: 高级工具

1) 常用手机号查询

l 关键技术: ExpandableListView, BaseExpandableListAdapter, SQLiteDatabase,打电话Intent

<ExpandableListView

android:id="@+id/elv_list"

android:layout_width="match_parent"

android:layout_height="match_parent"

android:groupIndicator="@drawable/expendable_group_selector"/>

<item android:drawable="@drawable/group_list"

android:state_expanded="true"/>

</selector>

2) 备份手机中的所有短信数据

l 技术: ContentResolver, 短信Uri, Cursor, XmlSerializer, XmlPullParser Gson

l 保存为xml文件格式

<?xml version="1.0" encoding="utf-8" standalone="yes" ?>

<smses>

<sms>

</sms>

<sms>

</sms>

</smses>

l 读取短信数据(查看mmssms.db数据库)

ContentResolver resolver = context.getContentResolver();

Uri uri = Uri.parse("content://sms");

String[] projection = {"address","date","type","body"};

Cursor cursor = resolver.query(uri , projection , null,null,null);

l XmlSerializer的使用样例

// 创建用于生成xml数据的对象

XmlSerializer serializer =Xml.newSerializer();

try {

//设置文件输出流

OutputStream os = new FileOutputStream(smsFile);

serializer.setOutput(os,"utf-8");

//开始写文档

serializer.startDocument("utf-8",true);

//写<smses>

serializer.startTag(null,"smses");

while (cursor.moveToNext()) {

//写<sms>

serializer.startTag(null,"sms");

String address = cursor.getString(0);

String date = cursor.getString(1);

String type = cursor.getString(2);

String body = cursor.getString(3);

//写<address>abc</address>

createTag(serializer, "address", address);

createTag(serializer, "date", date);

createTag(serializer, "type", type);

createTag(serializer, "body", body);

//写</sms>

serializer.endTag(null,"sms");

}

//写</smses>

serializer.endTag(null,"smses");

//结束写文档

serializer.endDocument();

} catch (Exception e) {

e.printStackTrace();

}

private void createTag(XmlSerializer serializer, String tagName,

String value) throws Exception {

serializer.startTag(null, tagName);

//写文本标签体

serializer.text(value);

serializer.endTag(null, tagName);

}

3) 还原备份的短信数据

l 技术: ContentResolver, 短信Uri, XmlPullParser, ProgressDialog

l XmlPullParser使用样例

try {

//创建pull解析器

XmlPullParser pullParser = Xml.newPullParser();

//设置xml文件流

pullParser.setInput(fis ,"utf-8");

//读取第一个事件类型

int eventType = pullParser.getEventType();

//不断循环读取,直到文档最后

while(eventType!=XmlPullParser.END_DOCUMENT) {

String tagName = null;

switch (eventType) {

case XmlPullParser.START_TAG://开始标签

//得到标签名

tagName = pullParser.getName();

if("address".equals(tagName)) {

//保存<address>的文本标签体内容

values.put("address", pullParser.nextText());

} else if("date".equals(tagName)) {

values.put("date", pullParser.nextText());

} else if("type".equals(tagName)) {

values.put("type", pullParser.nextText());

} else if("body".equals(tagName)) {

values.put("body", pullParser.nextText());

}

break;

case XmlPullParser.END_TAG://结束标签

tagName = pullParser.getName();

if("sms".equals(tagName)) {

//如果读到</sms>,就将数据保存到短信表中

resolver.insert(uri, values);

}

break;

default:

break;

}

//解析下一个单元数据,并保存其事件类型

eventType = pullParser.next();

}

} catch (Exception e) {

e.printStackTrace();

}

3.12. 功能十二: 手机杀毒

1) 计算机病毒与手机病毒

计算机病毒	对电脑有破坏性的程序
蠕虫病毒熊猫烧香	利用网络进行复制和传播，传染途径是通过网络和电子邮件目地: 显摆技术，验证技术
木马病毒	指通过特定的程序（木马程序）来控制另一台计算机目的：利益，账号：银行账号，游戏账号。
手机病毒	一种具有传染性、破坏性的手机程序. 其可利用发送短信、彩信，电子邮件，浏览网站，下载铃声，蓝牙等方式进行传播，会导致用户手机死机、关机、个人资料被删、向外发送垃圾邮件泄露个人信息、自动拨打电话、发短（彩）信等进行恶意扣费，甚至会损毁SIM卡、芯片等硬件，导致使用者无法正常使用手机目地:利益

2) 杀毒软件

l 作用: 用来定位出带病毒的软件应用，并提示用户将它们给删除。

l 基本原理:

n 收集病毒保存起来形成强大的病毒库, 如果安装的应用在病毒库中有记录, 杀毒软件就会提示其是病毒(手机杀毒)

n 它会监视软件的行为来判断其是否可能是病毒

1.监听是否开机启动

2.监听软件是否有打开摄像头

3.是否发邮件

4.是否很特别占用资源

3) 得到安装应用的信息

//得到所有包(包括已删除但安装目录还存在的)

List<PackageInfo> packages = pm.getInstalledPackages(PackageManager.GET_SIGNATURES);

for(PackageInfo packInfo : packages){

//应用名称

info.name = packInfo.applicationInfo.loadLabel(pm).toString();

//应用包名

info.packacgeName = packInfo.packageName;

//应用签名

String signature = packInfo.signatures[0].toCharsString();

}

4) 判断是否是病毒

//对应用签名进行md5加密

signature = MSUtils.md5(signature);

//查询病毒库表

String desc = AntiVirusQueryDao.getDesc(getApplicationContext(), signature);

if(desc==null) {//不是

info.isVirus =false;

} else {//是

info.isVirus =true;

}

5) 扫描杀毒时的旋转动画

RotateAnimation ra =new RotateAnimation(0, 360,

Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF,0.5f);

ra.setDuration(1000);

ra.setRepeatCount(RotateAnimation.INFINITE);//播放无限次

iv_antivirus_scanning.startAnimation(ra);

6) 自定义水平进度条

定义包含进度条图片的drawable文件

<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >

<item android:id="@android:id/background"

android:drawable="@drawable/security_progress_bg">

</item>

<item android:id="@android:id/secondaryProgress"

android:drawable="@drawable/security_progress_bg">

</item>

<item android:id="@android:id/progress"

android:drawable="@drawable/security_progress">

</item>

</layer-list>
