监听应用程序的安装、卸载

在AndroidManifest.xml中注册一个静态广播,监听安装的广播
android.intent.action.PACKAGE_ADDED 监听程序卸载的广播
android.intent.action.PACKAGE_REMOVED ,在广播中一定要加上 <data android:scheme="package" />
不然就监听不到

<receiver
  android:name=".AppInstallReceiver" android:enabled="true">
  <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>

在java代码中，需要写一个类继承 BroadcastReceiver

public class AppInstallReceiver extends BroadcastReceiver{


  @Override
  public void onReceive(Context context, Intent intent) {
      String action = intent.getAction();
      if(action.equals(Intent.ACTION_PACKAGE_ADDED)){
        Log.d("tag","app installed ");
      }else if(action.equals(Intent.ACTION_PACKAGE_REMOVED)){
        Log.d("tag","app uninstalled");
      }
  }

}

可以通过intent获取应用的包名
String pkgName = intent.getDataString().substring(8)
