第一、 新建监听类:BootReceiver继承BroadcastReceiver
package com.rongfzh.yc; import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent; public class BootReceiver extends BroadcastReceiver{ @Override public void onReceive(Context context, Intent intent){ //接收安装广播 if (intent.getAction().equals("android.intent.action.PACKAGE_ADDED")) { String packageName = intent.getDataString(); System.out.println("安装了:" +packageName + "包名的程序"); } //接收卸载广播 if (intent.getAction().equals("android.intent.action.PACKAGE_REMOVED")) { String packageName = intent.getDataString(); System.out.println("卸载了:" + packageName + "包名的程序"); } } }
第二、 修改AndroidManifest.xml配置文件,添加广播介绍,添加监听的权限
<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.rongfzh.yc" android:versionCode="1" android:versionName="1.0" > <uses-sdk android:minSdkVersion="7" /> <application android:icon="@drawable/ic_launcher" android:label="@string/app_name" > <activity android:name=".PakDetectActivity" android:label="@string/app_name" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <receiver android:name=".BootReceiver" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.PACKAGE_ADDED" /> <action android:name="android.intent.action.PACKAGE_REMOVED" /> <data android:scheme="package" /> </intent-filter> </receiver> </application> <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.RESTART_PACKAGES"/> <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/> </manifest>
3、运行程序,卸载一个程序ApiDemos程序打印日志如下
System.out(1513): 卸载了:package:com.example.android.apis包名的程序
4、安装腾讯微博,打印日志如下:
System.out(1513): 安装了:package:com.tencent.WBlog包名的程序
2) 代码方式
一般在Activity的onStart()方法中注册监听,在onDestroy()方法中注销监听(也可以在onStop()方法中注销,其生命周期注销时结束)
@Override public void onStart(){ super.onStart(); installedReceiver = new MyInstalledReceiver(); IntentFilter filter = new IntentFilter(); filter.addAction("android.intent.action.PACKAGE_ADDED"); filter.addAction("android.intent.action.PACKAGE_REMOVED"); filter.addDataScheme("package"); this.registerReceiver(installedReceiver, filter); } @Override public void onDestroy(){ if(installedReceiver != null) { this.unregisterReceiver(installedReceiver); } super.onDestroy(); }
程序监听成功。
