Question

当我当时从应用程序处于后台运行时从Firebase发送通知时，通知来了，但是通知声音没有播放。但是当该应用运行时，声音正在播放。当我向较低版本的应用发送通知时出现问题，请关闭我的代码

这是我的广播接收器

 mRegistrationBroadcastReceiver = new BroadcastReceiver() {
            @RequiresApi(api = Build.VERSION_CODES.O)
            @Override
            public void onReceive(Context context, Intent intent) {
                if (intent.getAction().equals(Config.REGISTRATION_COMPLETE)) {
                    FirebaseMessaging.getInstance().subscribeToTopic(Config.TOPIC_GLOBAL);
                } else if (intent.getAction().equals(Config.PUSH_NOTIFICATION)) {


                    pendingListAdapter = new PendingListAdapter(MainActivity.this, getPendingList(str_society_id, str_staff_id));
                    Functions.setDatatoRecyclerView(rv_pendings, pendingListAdapter, MainActivity.this);
                    String message = intent.getStringExtra("message");

                    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
                        NotificationManager mNotificationManager =
                                (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
                        int importance = mNotificationManager.IMPORTANCE_HIGH;

                        mChannel.setLightColor(Color.RED);
                        mChannel.enableVibration(true);
                        Uri soundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
                        Ringtone r = RingtoneManager.getRingtone(MainActivity.this, soundUri);
                        r.play();
                        mChannel.setVibrationPattern(new long[]{100, 200, 300, 400, 500, 400, 300, 200, 400});


                        mNotificationManager.createNotificationChannel(mChannel);
                        notificationUtils = new NotificationUtils(MainActivity.this);
                        notificationUtils.playNotificationSound();

                        MyNotificationManager.getInstance(MainActivity.this).displayNotification("Greetings", message);
                        Toast.makeText(getApplicationContext(), "Push notification: " + message, Toast.LENGTH_LONG).show();
                    } else {
                        Notification notification = new Notification.Builder(MainActivity.this)
                                .setCategory(Notification.CATEGORY_MESSAGE)
                                .setContentTitle("Greetings")
                                .setContentText(message)
                                .setSmallIcon(R.drawable.logo_app)
                                .setAutoCancel(true)

                                .setVisibility(Notification.VISIBILITY_PUBLIC).build();
                        NotificationManager notificationManager =
                                (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
                        notificationManager.notify(1, notification);
                        notificationUtils = new NotificationUtils(MainActivity.this);
                        notificationUtils.playNotificationSound();


                    }

                    notification_count = sharedPreferencesDatabase.getData(Config.NOTIFICATION_COUNT);
                    int i_notification_count = 0;
                    if (!TextUtils.isEmpty(notification_count) && !TextUtils.equals(notification_count, "null")) {

                    }

                    i_notification_count = i_notification_count + 1;
                    sharedPreferencesDatabase.addData(Config.NOTIFICATION_COUNT, "" + i_notification_count);

                    if (i_notification_count != 0) {

                    }
                }
            }
        };

这是我的Firebase FirebaseInstanceIdService

public class MyFirebaseInstanceIDService extends FirebaseInstanceIdService {
    private static final String TAG = MyFirebaseInstanceIDService.class.getSimpleName();

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

        storeRegIdInPref(refreshedToken);

        registrationComplete.putExtra("token", refreshedToken);
        LocalBroadcastManager.getInstance(this).sendBroadcast(registrationComplete);
    }

    private void sendRegistrationToServer(final String token) {
        // sending gcm token to server

    }

        SharedPreferences pref = getApplicationContext().getSharedPreferences(Config.SHARED_PREFERENCE_DB_NAME, 0);
        SharedPreferences.Editor editor = pref.edit();
        editor.putString("regId", token);
        editor.commit();
    }
}

这是我的FirebaseMessagingService

public class MyFirebaseMessagingService extends FirebaseMessagingService {

    private static final String TAG = MyFirebaseMessagingService.class.getSimpleName();

    private NotificationUtils notificationUtils;

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
