The android music player listens to the phone status implementation code

The following code is the status of monitoring the phone, the code is simple without introduction to see the code directly:

 private boolean mResumeAfterCall = false;
 private PhoneStateListener mPhoneStateListener = new PhoneStateListener() {
  @Override
  public void onCallStateChanged(int state, String incomingNumber) {
   if (state == TelephonyManager.CALL_STATE_RINGING) {
    AudioManager audioManager = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
    int ringvolume = audioManager
      .getStreamVolume(AudioManager.STREAM_RING);
    if (ringvolume > 0) {
     mResumeAfterCall = (player.isPlaying() || mResumeAfterCall);
     try {
      stub.pause();
     } catch (RemoteException e) {
      // TODO Auto-generated catch block
      e.printStackTrace();
     }
    }
   } else if (state == TelephonyManager.CALL_STATE_OFFHOOK) {
    // pause the music while a conversation is in progress
    mResumeAfterCall = (player.isPlaying() || mResumeAfterCall);
    try {
     stub.pause();
    } catch (RemoteException e) {
     // TODO Auto-generated catch block
     e.printStackTrace();
    }
   } else if (state == TelephonyManager.CALL_STATE_IDLE) {
    // start playing again
    if (mResumeAfterCall) {
     // resume playback only if music was playing
     // when the call was answered
     try {
      stub.resume();
     } catch (RemoteException e) {
      // TODO Auto-generated catch block
      e.printStackTrace();
     }
     mResumeAfterCall = false;
    }
   }
  }
 };

When you use it, add it to service's oncreate, as follows:

 public void onCreate() {
  player = new MediaPlayer();
  super.onCreate();
  TelephonyManager tmgr = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
  tmgr.listen(mPhoneStateListener, PhoneStateListener.LISTEN_CALL_STATE);
  IntentFilter filter = new IntentFilter();

  filter.addAction(SERVICECMD);
  filter.addAction(PAUSE_ACTION);
  receiver = new MusicServiceReceiver();
  registerReceiver(receiver, filter);
 }

Just delete it in ondestroy

 public void onDestroy() {
  // Log.e(TAG, "onDestroy" +player.isPlaying() );
  // System.out.println("onDestroy");
  unregisterReceiver(receiver);
  player.release();
  player = null;

  TelephonyManager tmgr = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
  tmgr.listen(mPhoneStateListener, 0);
  super.onDestroy();
 }
