监测耳机拔除广播延迟ACTION_HEADSET_PLUG broadcast delay

问题描述：

监听系统广播ACTION_HEADSET_PLUG，耳机拔出时暂停播放，然而实际处理时会有延迟，耳机拔出并没有立即暂停播放，而是延迟几秒之后才暂停

解决办法：

监听AudioManager.ACTION_AUDIO_BECOMING_NOISY，解决了这个延迟的问题

public class EarPhoneReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
//        if (intent.getAction().equals(Intent.ACTION_HEADSET_PLUG)){
          if (intent.getAction().equals(AudioManager.ACTION_AUDIO_BECOMING_NOISY)){
                   //处理事件
          }

    }
}



   private void registerEarPhoneReceiver(){
        earPhoneReceiver = new EarPhoneReceiver();
        IntentFilter filter = new IntentFilter(AudioManager.ACTION_AUDIO_BECOMING_NOISY);
 //       filter.addAction("android.intent.action.HEADSET_PLUG");
        registerReceiver(earPhoneReceiver,filter);
    }

弊端：监测不到耳机插入事件
