二つの方法
 
1、コード
1, Define a class extends BroadcastReceiver;2, Register broadcast receiver;
 
 

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. 
registerReceiver(receiver, filter);

 
 
2、XML
 
 

<data android:scheme="package"></data>

 This line is very important. Otherwise, broadcast can't be received. この仕事はとても重要です.
 

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

 
 

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());  
    }  
  
}
