안드로이드에서 오디오 파일 재생후 foreground를 통해서 들어오면 정지가안돼네요

Question

오디오 재생하는것을 하고있는데요 오디오를 재생하고 있을 때 앱을 나가거나 종료해도 notification을 통해서 지속적으로 보여주는 것을 했습니다. 그런데 이 notification을 클릭해서 화면으로 들어가면 음악 정지를 누르면 정지가 되지 않더라구요.. 왜 그런지 모르겠네요.. 조언 부탁드립니다.MainActivity.class &#64;Override public void onClick(View v) { switch (v.getId()) { case R.id.button1: audioPlay.startAudio(); Intent startIntent &#61; new Intent(MainActivity.this, ForgroundService.class); startIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP); startIntent.setAction(Constants.ACTION.STARTFOREGROUND_ACTION); startService(startIntent); break; case R.id.button2: audioPlay.stopAudio(); Intent stopIntent &#61; new Intent(MainActivity.this, ForgroundService.class); stopIntent.setAction(Constants.ACTION.STOPFOREGROUND_ACTION); startService(stopIntent); break; case R.id.button3: Intent startIntent1 &#61; new Intent(MainActivity.this, ForgroundService.class); startIntent1.setAction(Constants.ACTION.STARTFOREGROUND_ACTION); startService(startIntent1); break; default: break; } } foreground.class public class ForgroundService extends Service { private static final String LOG_TAG &#61; &#34;ForegroundService&#34;; &#64;Override public void onCreate() { super.onCreate(); } &#64;Override public int onStartCommand(Intent intent, int flags, int startId) { if (intent.getAction().equals(Constants.ACTION.STARTFOREGROUND_ACTION)) { Log.i(LOG_TAG, &#34;Received Start Foreground Intent &#34;); Intent notificationIntent &#61; new Intent(this, MainActivity.class); notificationIntent.setAction(Constants.ACTION.MAIN_ACTION); notificationIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK); PendingIntent pendingIntent &#61; PendingIntent.getActivity(this, 0, notificationIntent, 0); Intent previousIntent &#61; new Intent(this, ForgroundService.class); previousIntent.setAction(Constants.ACTION.PREV_ACTION); PendingIntent ppreviousIntent &#61; PendingIntent.getService(this, 0, previousIntent, 0); Intent playIntent &#61; new Intent(this, ForgroundService.class); playIntent.setAction(Constants.ACTION.PLAY_ACTION); PendingIntent pplayIntent &#61; PendingIntent.getService(this, 0, playIntent, 0); Intent nextIntent &#61; new Intent(this, ForgroundService.class); nextIntent.setAction(Constants.ACTION.NEXT_ACTION); PendingIntent pnextIntent &#61; PendingIntent.getService(this, 0, nextIntent, 0); Bitmap icon &#61; BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher); Notification notification &#61; new NotificationCompat.Builder(this) .setContentTitle(&#34;Truiton Music Player&#34;) .setTicker(&#34;Truiton Music Player&#34;) .setContentText(&#34;My Music&#34;) .setSmallIcon(R.drawable.ic_launcher) .setLargeIcon( Bitmap.createScaledBitmap(icon, 128, 128, false)) .setContentIntent(pendingIntent) .setOngoing(true) .addAction(android.R.drawable.ic_media_previous, &#34;Previous&#34;, ppreviousIntent) .addAction(android.R.drawable.ic_media_play, &#34;Play&#34;, pplayIntent) .addAction(android.R.drawable.ic_media_next, &#34;Next&#34;, pnextIntent).build(); startForeground(Constants.NOTIFICATION_ID.FOREGROUND_SERVICE, notification); } else if (intent.getAction().equals(Constants.ACTION.PREV_ACTION)) { Log.i(LOG_TAG, &#34;Clicked Previous&#34;); } else if (intent.getAction().equals(Constants.ACTION.PLAY_ACTION)) { Log.i(LOG_TAG, &#34;Clicked Play&#34;); } else if (intent.getAction().equals(Constants.ACTION.NEXT_ACTION)) { //MainActivity.exoPlayer.stop(); Log.i(LOG_TAG, &#34;Clicked Next&#34;); } else if (intent.getAction().equals(Constants.ACTION.STOPFOREGROUND_ACTION)) { Log.i(LOG_TAG, &#34;Received Stop Foreground Intent&#34;); stopForeground(true); stopSelf(); } return START_STICKY; } &#64;Override public void onDestroy() { super.onDestroy(); Log.i(LOG_TAG, &#34;In onDestroy&#34;); } &#64;Override public IBinder onBind(Intent intent) { // Used only in case of bound services.

혹시 AUDIO FOCUS라고 들어보셨나요? 안드로이드에서 여러 앱이 오디오를 플레이하는 문제를 위해 AUDIO FOCUS를 사용한답니다. 즉 PLAY(PAUSE)모두 AUDIO FOCUS를 재요청 해줘야 가능한거 아닌가요? AudioManager am &#61; mContext.getSystemService(Context.AUDIO_SERVICE); ... // Request audio focus for playback int result &#61; am.requestAudioFocus(afChangeListener, // Use the music stream. AudioManager.STREAM_MUSIC, // Request permanent focus. AudioManager.AUDIOFOCUS_GAIN); if (result &#61;&#61; AudioManager.AUDIOFOCUS_REQUEST_GRANTED) { am.registerMediaButtonEventReceiver(RemoteControlReceiver); // Start playback. }
