android - Firebase 通知在后台不工作

Question

我需要帮助。 Firebase 通知在后台不工作。这是我的代码:

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {

    Log.d(TAG, "FROM:" + remoteMessage.getFrom());
   sharedPreference = getSharedPreferences(Global.SECURETRADE, 0);
    UID = sharedPreference.getString(Global.ID, "");


        Uri defaultSoundUri=RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION)`enter code here`;

        NotificationCompat.Builder notificationBuilder = new
                NotificationCompat.Builder(this);

        if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {

            notificationBuilder.setSmallIcon(R.mipmap.small_secure_trade_app_icon);

        } else {

            notificationBuilder.setSmallIcon(R.drawable.small_secure_trade_app_icon);
        }

        notificationBuilder.setLargeIcon(BitmapFactory.decodeResource(this.getResources(), R.drawable.securetrade_icon));
        notificationBuilder.setContentTitle(remoteMessage.getData().get("title"));
        notificationBuilder.setContentText(remoteMessage.getData().get("body"));
        notificationBuilder.setAutoCancel(true);
        notificationBuilder.setSound(defaultSoundUri);
        notificationBuilder.setContentIntent(pendingIntent);

        NotificationManager notificationManager =
                (NotificationManager)
                        getSystemService(Context.NOTIFICATION_SERVICE);

        notificationManager.notify(0, notificationBuilder.build());

    }




}

只需从您通过推送通知发送的 json 中删除“通知”部分。只需发送“数据”部分，onMessageReceived 将正常工作
