Android NotificationCompat关闭并再次显示

Question

您可以在以下位置找到我的源代码：https://github.com/Ali-Rezaei/ExoPlayerSample

我的服务中有一个ExoPlayer：

public class MainService extends Service implements ExoPlayer.EventListener {

    private SimpleExoPlayer mExoPlayer;
    private static MediaSessionCompat mMediaSession;

    @Override
    public void onCreate() {
        super.onCreate();

        // Initialize the Media Session.
        initializeMediaSession();

        // Initialize the player.
        initializePlayer();
    }

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

@Override
    public void onTaskRemoved(Intent rootIntent) {
        super.onTaskRemoved(rootIntent);
        Intent broadcastIntent = new Intent(this, RestartService.class);
        broadcastIntent.setAction("restartService");
        sendBroadcast(broadcastIntent);
    }

    /**
     * Release ExoPlayer.
     */
    private void releasePlayer() {
        mNotificationManager.cancelAll();
        mExoPlayer.removeListener(this);
        mExoPlayer.stop();
        mExoPlayer.release();
        mExoPlayer = null;
    }

    /**
     * Release the player when the service is destroyed.
     */
    @Override
    public void onDestroy() {
        super.onDestroy();
        releasePlayer();
        mMediaSession.setActive(false);
    }

/**
     * Broadcast Receiver registered to receive the MEDIA_BUTTON intent coming from clients.
     */
    public static class MediaReceiver extends BroadcastReceiver {

        public MediaReceiver() {
        }

        @Override
        public void onReceive(Context context, Intent intent) {
            MediaButtonReceiver.handleIntent(mMediaSession, intent);
        }
    }

    public static class RestartService extends BroadcastReceiver {

        @Override
        public void onReceive(Context context, Intent intent) {
            context.startService(new Intent(context, MainService.class));
        }
    }
}

我正在显示如下通知：

NotificationCompat.Builder builder = new NotificationCompat.Builder(this, "Id");
Notification notificationCompat = builder.build();
    if (state.getState() == PlaybackStateCompat.STATE_PAUSED) {
        stopForeground(true);
        mNotificationManager.cancel(NOTIFICATION_ID);
        mNotificationManager.notify(NOTIFICATION_ID, notificationCompat);
    } else {
        startForeground(NOTIFICATION_ID, notificationCompat);
    }

[当我关闭应用程序时（使用设备后退或主页按钮），或者从最近的应用程序中关闭您的应用程序（手动杀死该应用程序，然后单击暂停/播放通知->通知将关闭并再次显示。我的期望：我不希望像SoundCloud应用程序那样解雇并再次显示。我想念什么？

StopForground时，我不应该删除通知。因此，我的逻辑应如下：

Notification notificationCompat = builder.build();
        if (state.getState() == PlaybackStateCompat.STATE_PAUSED) {
            stopForeground(false);
            mNotificationManager.notify(NOTIFICATION_ID, notificationCompat);
        } else {
            startForeground(NOTIFICATION_ID, notificationCompat);
        }
