如何使用扬声器检测警报响铃或其他应用程序？

Question

我正在开发一个音乐应用程序.我想检测其他应用程序使用扬声器或闹铃响铃播放/暂停音乐.

对于电话,我使用PhoneStateListener.我尝试使用OnAudioFocusChangeListener来检测其他音频.但没有奏效.

我想知道如何解决这个问题.

我解决了我的默认警报应用问题:

public static final String ALARM_ALERT_ACTION = "com.android.deskclock.ALARM_ALERT";
public static final String ALARM_SNOOZE_ACTION = "com.android.deskclock.ALARM_SNOOZE";
public static final String ALARM_DISMISS_ACTION = "com.android.deskclock.ALARM_DISMISS";
public static final String ALARM_DONE_ACTION = "com.android.deskclock.ALARM_DONE";

private BroadcastReceiver mReceiver = new BroadcastReceiver() 
{
    @Override
    public void onReceive(Context context, Intent intent) 
    {
          String action = intent.getAction();
          if (action.equals(ALARM_ALERT_ACTION) || action.equals(ALARM_DISMISS_ACTION) || action.equals(ALARM_SNOOZE_ACTION) || action.equals(ALARM_DONE_ACTION)) 
          {
              // for play/pause mediaplayer
              playPause();
          }
    }
};


@Override
public void onCreate(Bundle savedInstanceState) 
{
    IntentFilter filter = new IntentFilter(ALARM_ALERT_ACTION);
    filter.addAction(ALARM_DISMISS_ACTION);
    filter.addAction(ALARM_SNOOZE_ACTION);
    filter.addAction(ALARM_DONE_ACTION);
    registerReceiver(mReceiver, filter);
}
