내 Android Java 백그라운드 서비스에서 도움이 필요합니다. 호출이 감지되었을 때 중지하려면

Question

내 프로젝트 중 하나에 배경 음악 재생 서비스를 만들었습니다. 작동하지만 재생 중일 때 전화가 걸려서 다른 앱처럼 미디어가 멈추지 않았습니다. 또한 내가 전화에 응답했을 때 음악은 여전히 ​​연주했다.

package mypackage; 

import android.app.Notification; 
import android.app.NotificationManager; 
import android.app.Service; 
import android.content.Context; 
import android.content.Intent; 
import android.graphics.Bitmap; 
import android.media.AudioManager; 
import android.media.MediaPlayer; 
import android.media.MediaPlayer.OnCompletionListener; 
import android.os.IBinder; 
import android.support.v7.app.NotificationCompat; 
import android.widget.Toast; 

import mypackage.R; 

public class StreamPlayer extends Service implements OnCompletionListener { 
    MediaPlayer mediaPlayer; 
    Notification noti; 
    android.support.v4.app.NotificationCompat.Builder noticom; 
    NotificationManager notiman; 

    @Override 
    public IBinder onBind(Intent intent) { 
     return null; 
    } 

    @Override 
    public void onCreate() { 

     mediaPlayer = new MediaPlayer(); 
     mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC); 
     mediaPlayer.setOnBufferingUpdateListener(new MediaPlayer.OnBufferingUpdateListener() { 
      @Override 
      public void onBufferingUpdate(MediaPlayer mp, int percent) { 
       Toast.makeText(StreamPlayer.this, "Buffering", Toast.LENGTH_LONG).show(); 
      } 
     }); 
     try { 
      mediaPlayer.setDataSource("http://149.56.185.83:8138/stream"); 
      mediaPlayer.prepare(); 
     }catch (Exception ex){ 
     } 
     mediaPlayer.setOnCompletionListener(this); 
     noticom = new NotificationCompat.Builder(this) 
       .setSmallIcon(R.mipmap.ic_launcher) 
       .setCategory(MEDIA_SESSION_SERVICE) 
       .setAutoCancel(true) 
       .setContentTitle("Sample Streamed Music Player") 
       .setOngoing(true) 
       .setPriority(NotificationCompat.PRIORITY_HIGH) 
       .setContentText("Now Playing") 
       .setCategory(NotificationCompat.CATEGORY_EVENT); 
     notiman = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); 
    } 


    @Override 
    public int onStartCommand(Intent intent, int flags, int startId) { 
     if (!mediaPlayer.isPlaying()) { 
      mediaPlayer.start(); 
      Toast.makeText(StreamPlayer.this, "Now Playing", Toast.LENGTH_SHORT).show(); 
      noti = noticom.build(); 
      notiman.notify(2017,noti); 
     } 
     return START_STICKY; 
    } 

    public void onDestroy() { 
     if (mediaPlayer.isPlaying()) { 
      mediaPlayer.stop(); 
      noticom.setOngoing(false); 
      noticom.setContentText("Stopped"); 
      Toast.makeText(StreamPlayer.this, "Stopped", Toast.LENGTH_SHORT).show(); 
      noti = noticom.build(); 
      notiman.notify(2017,noti); 
     } 
     mediaPlayer.release(); 
    } 

    public void onCompletion(MediaPlayer _mediaPlayer) { 
     stopSelf(); 
    } 

} 

아무도 그 문제를 해결하는 방법을 알고 있습니까?

Notification notificationFunction(){ 
     Notification.Builder mBuilder = new Notification.Builder(this); 

/*customize notification*/ 

      NotificationManager mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); 
      return mBuilder.build(); 
    } 

Answer 1

에 나는 해결책을 발견해야합니다. 지원에 감사드립니다. 내가 코드를 사용 후 :

public class MyActivity extends Activity implements OnAudioFocusChangeListener { 

private AudioManager mAudioManager; 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    ... 
    mAudioManager = (AudioManager) getSystemService(Context.AUDIO_SERVICE); 
    mAudioManager.requestAudioFocus(this, AudioManager.STREAM_MUSIC, AudioManager.AUDIOFOCUS_GAIN); 
    ... 
} 

@Override 
public void onDestroy(){ 
    super.onDestroy(); 
    ... 
    mAudioManager.abandonAudioFocus(this); 
    ... 
} 


@Override 
public void onAudioFocusChange(int focusChange) { 
    if(focusChange<=0) { 
     //LOSS -> PAUSE 
    } else { 
     //GAIN -> PLAY 
    } 
}

먼저 Service.START_REDELIVER_INTENT; 두 번째 호출 startForeground(int id, notificationFunction());

로 돌아가이 notificationFunction이 될 수는()는 음악 플레이어에 대한 당신은 check this
