Broadcast in ausstehende Absicht funktioniert nicht über Benachrichtigung

Question

Ich möchte Aktion in Benachrichtigung hinzufügen, die beim Senden Broadcast an den gleichen Dienst sendet, in dem ein Lied spielt, und dort in Boradcast Empfänger-Klasse, ich möchte den spielenden Song stoppen. Aber ich kann nicht bekommen, dass die Sendung vom Empfänger empfangen wird. Eine detaillierte Lösung würde sehr geschätzt werden.

package com.example.ranasarmadrajput.servicestask; 

import android.content.Intent; 
import android.media.AudioManager; 
import android.media.MediaPlayer; 
import android.net.Uri; 
import android.support.v7.app.AppCompatActivity; 
import android.os.Bundle; 
import android.view.View; 
import android.widget.Toast; 

public class MainActivity extends AppCompatActivity { 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
     Intent i = getIntent(); 
     if(i.getAction().equals("playpause")){ 
      Toast.makeText(this,"sss",Toast.LENGTH_LONG).show(); 
     } 
    } 
    public void selectsong(View view){ 
     Intent intent= new Intent(android.content.Intent.ACTION_GET_CONTENT); 
     String type = "audio/*"; 
     intent.setType(type); 
     startActivityForResult(intent,2); 
    } 

    @Override 
    protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
     if (requestCode == 2) { 
      if (data != null) { 
       Intent intent = new Intent(this,musicplayer.class); 
       intent.setAction("Play"); 
       intent.setData(data.getData()); 
       startService(intent); 

      } 
     } 
    }}

folgen Sie diesem Thread auf Google Code https://code.google.com/p/android/issues/detail?id=61850

es zu beheben, müssen Sie PendingIntent.FLAG_CANCEL_CURRENT Flagge zu Ihrem PendingIntent hinzuzufügen.

PendingIntent stopPendingIntent2 = PendingIntent.getBroadcast(this, 0, 
      stopIntent2, PendingIntent.FLAG_CANCEL_CURRENT);
