推送可以及时,主动的与用户发起交互
(1)继承jar包,照示例AndroidManifest.xml添加.
(2)自定义MyApp继承自Application,在onCreate方法中调用JPushInterface.init(MainActivity.this);
或者在Activity的onCreate中调用.
(3)另外,在activity的onResume方法要调用JPushInterface.onResume(this);否则,推送不会出现,
在onPause中调用JPushInterface.onPause(this);
这样,可以通过服务器往安装了App的所有用户发送一条推送.
通过Alias往客户端发送信息.
在客户端的onCreate中
JPushInterface.setAlias(MainActivity.this, "aa", new TagAliasCallback() {
@Override
public void gotResult(int arg0, String arg1, Set<String> arg2) {
Log.e("info",arg1+"-----------");
//arg1是tag
}
});这句就是将"aa"当成该设备的别名,达到往指定客户端发送消息的目的.
别名和签名设置的异常处理
有时会因为网络原因,有一定几率设置别名或标签失败.
privatevoidsetAlias() {
EditText aliasEdit = (EditText) findViewById(R.id.et_alias);
String alias = aliasEdit.getText().toString().trim();
if(TextUtils.isEmpty(alias)) {
Toast.makeText(PushSetActivity.this,R.string.error_alias_empty, Toast.LENGTH_SHORT).show();
return;
}
if(!ExampleUtil.isValidTagAndAlias(alias)) {
Toast.makeText(PushSetActivity.this,R.string.error_tag_gs_empty, Toast.LENGTH_SHORT).show();
return;
}
// 调用 Handler 来异步设置别名
mHandler.sendMessage(mHandler.obtainMessage(MSG_SET_ALIAS, alias));
}
privatefinalTagAliasCallback mAliasCallback =newTagAliasCallback() {
@Override
publicvoidgotResult(intcode, String alias, Set<String> tags) {
String logs ;
switch(code) {
case:
logs ="Set tag and alias success";
Log.i(TAG, logs);
break;
case:
logs ="Failed to set alias and tags due to timeout. Try again after 60s.";
Log.i(TAG, logs);
mHandler.sendMessageDelayed(mHandler.obtainMessage(MSG_SET_ALIAS, alias),*);
break;
default:
logs ="Failed with errorCode = "+ code;
Log.e(TAG, logs);
}
ExampleUtil.showToast(logs, getApplicationContext());
}
};
privatestaticfinalintMSG_SET_ALIAS =;
privatefinalHandler mHandler =newHandler() {
@Override
publicvoidhandleMessage(android.os.Message msg) {
super.handleMessage(msg);
switch(msg.what) {
caseMSG_SET_ALIAS:
Log.d(TAG,"Set alias in handler.");
// 调用 JPush 接口来设置别名。
JPushInterface.setAliasAndTags(getApplicationContext(), (String) msg.obj,null, mAliasCallback);
break;
default:
Log.i(TAG,"Unhandled msg - "+ msg.what);
}
}
};自定义通知栏的样式
自定义样式放在init()之后.
CustomPushNotificationBuilder builder=new CustomPushNotificationBuilder(MainActivity.this, R.layout.my_push, R.id.iv_push, R.id.tv_title, R.id.tv_content);
builder.statusBarDrawable=R.drawable.ic_category_2;//最顶层状态栏小图标
builder.layoutIconDrawable=R.drawable.ic_category_2; //下拉状态时显示的通知图标.
JPushInterface.setPushNotificationBuilder(2, builder);
JPushInterface.setDefaultPushNotificationBuilder(builder); //设置该对话框为默认.自定义消息:
所接收的消息不再局限于Notification,而是可以直接取出消息中的内容,从而用自己的方式显示给用户.
此时需要自定义一个MyReceiver继承自BroadcastReceiver.
public class MyReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context ctx, Intent intent) {
Bundle bundle =intent.getExtras(); //接受到消息
Log.e("info", "[MyReceiver] onReceive - " + intent.getAction() + ", extras: " + printBundle(bundle));
if (JPushInterface.ACTION_REGISTRATION_ID.equals(intent.getAction())) {
String regId = bundle.getString(JPushInterface.EXTRA_REGISTRATION_ID);
Log.d("info", "[MyReceiver] 接收Registration Id : " + regId);
//send the Registration Id to your server...
} else if (JPushInterface.ACTION_MESSAGE_RECEIVED.equals(intent.getAction())) {
Log.d("info", "[MyReceiver] 接收到推送下来的自定义消息: " + bundle.getString(JPushInterface.EXTRA_MESSAGE));
// processCustomMessage(ctx, bundle);
} else if (JPushInterface.ACTION_NOTIFICATION_RECEIVED.equals(intent.getAction())) {
Log.d("info", "[MyReceiver] 接收到推送下来的通知");
int notifactionId = bundle.getInt(JPushInterface.EXTRA_NOTIFICATION_ID);
Log.d("info", "[MyReceiver] 接收到推送下来的通知的ID: " + notifactionId);
} else if (JPushInterface.ACTION_NOTIFICATION_OPENED.equals(intent.getAction())) {
Log.d("info", "[MyReceiver] 用户点击打开了通知");
JPushInterface.reportNotificationOpened(ctx, bundle.getString(JPushInterface.EXTRA_MSG_ID));
// //打开自定义的Activity
Intent i = new Intent(ctx, TwoActivity.class);
i.putExtras(bundle);
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
ctx.startActivity(i);
}
}
// 打印所有的 intent extra 数据
private static String printBundle(Bundle bundle) {
StringBuilder sb = new StringBuilder();
for (String key : bundle.keySet()) {
if (key.equals(JPushInterface.EXTRA_NOTIFICATION_ID)) {
sb.append("/nkey:" + key + ", value:" + bundle.getInt(key));
} else {
sb.append("/nkey:" + key + ", value:" + bundle.getString(key));
}
}
return sb.toString();
}在类中接收完消息后,还需要在AndroidManifest.xml中添加
<!--自定义接收 -->
<receiver
android:name="com.lj.pushdemo1.MyReceiver"
android:enabled="true">
<intent-filter>
<action android:name="cn.jpush.android.intent.REGISTRATION" />
<action android:name="cn.jpush.android.intent.MESSAGE_RECEIVED" />
<action android:name="cn.jpush.android.intent.NOTIFICATION_RECEIVED" />
<action android:name="cn.jpush.android.intent.NOTIFICATION_OPENED" />
<category android:name="com.lj.pushdemo1" />
</intent-filter>
</receiver>获取 RegistrationID API
集成了JPush SDK的应用程序第一次注册到JPush服务器时,服务器会返回一个唯一的该设备的标识:RegistertionID.
String id=JPushInterface.getRegistrationID(MainActivity.this);
调用网络接口来发送消息
sendno:发送的编号.
app_key: 应用程序的appKey
receiver_type:接受者的类型 ----2.指定tag----3.指定alias----4.广播----5.根据registrationId进行推送.
msg_content:发送的内容,在这里必须要JSON格式.
platform:要发送的平台
verfication_code:将sendno+receiver_typ+receiver_values+API MasterSecret(在应用的详细信息里面)字符串拼接起来后,用md5加密
设置保留最近通知条数 API
JPushInterface.init(context); JPushInterface.setLatestNotificationNumber(context,);保留最近的3条
