android 监听程序卸载

 1, 定义一个class 继承BroadcastReceiver;

 2, 给Receiver注册广播;

    

UninstallApp receiver = new UninstallApp();　　IntentFilter filter = new IntentFilter(Intent.ACTION_PACKAGE_INSTALL);　　filter.addAction(Intent.ACTION_PACKAGE_REMOVED);　　filter.addDataScheme("package"); //This line is very important. Otherwise, broadcast can't be received.这一行很得要　　registerReceiver(receiver, filter); 

 

　2、XML

　　 This line is very important. Otherwise, broadcast can't be received. 这一行很重要

　　Java代码

　　

< receiver Android:name="UninstallApp">　　< intent-filter>　　< action android:name="android.intent.action.PACKAGE_REMOVED" />　　< data android:scheme="package">　　< /intent-filter>　　< /receiver>　　< receiver android:name="UninstallApp">　　< intent-filter>　　< action android:name="android.intent.action.PACKAGE_REMOVED" />　　< data android:scheme="package">　　< /intent-filter>　　< /receiver>

　　Java代码

　　

import android.content.BroadcastReceiver;　　import android.content.Context;　　import android.content.Intent;　　import android.util.Log;　　public class UninstallApp extends BroadcastReceiver {　　@Override　　public void onReceive(Context context, Intent intent) {　　Log.e("intent", "intent="+intent.getAction());　　}　　}
