多个FirebaseMessagingServices

Question

我已使用Firebase在我的应用中创建了一个聊天记录。当应用程序用户收到消息时，将启动推送通知。 现在，我需要使用OneSignal来管理应用程序中的推送通知。

我的问题是，使用当前的FirebaseMessagingService会遇到异常。

我放置代码以处理聊天通知的方式与OneSignal管理通知的方式不同。

是否可以考虑多个FirebaseMessagingServices？一个用于聊天，另一个用于推送通知？。

这是我当前的FirebaseMessagingServices中的代码：

public class MyFirebaseMessaging extends FirebaseMessagingService {

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        super.onMessageReceived(remoteMessage);

        String sented = remoteMessage.getData().get("sented");
        String user = remoteMessage.getData().get("user");

        SharedPreferences preferences = getSharedPreferences("PREFS", MODE_PRIVATE);
        String currentUser = preferences.getString("currentuser", "none");

        FirebaseUser firebaseUser = FirebaseAuth.getInstance().getCurrentUser();

        if (firebaseUser != null && sented.equals(firebaseUser.getUid())){
            if (!currentUser.equals(user)) {
                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
                    sendOreoNotification(remoteMessage);
                } else {
                    sendNotification(remoteMessage);
                }
            }
        }
    }

    private void sendOreoNotification(RemoteMessage remoteMessage){
        String user = remoteMessage.getData().get("user");
        String icon = remoteMessage.getData().get("icon");
        String title = remoteMessage.getData().get("title");
        String body = remoteMessage.getData().get("body");

        RemoteMessage.Notification notification = remoteMessage.getNotification();
        int j = Integer.parseInt(user.replaceAll("[\\D]", ""));
        Intent intent = new Intent(this, MessageActivity.class);
        Bundle bundle = new Bundle();
        bundle.putString("userid", user);
        intent.putExtras(bundle);
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        PendingIntent pendingIntent = PendingIntent.getActivity(this, j, intent, PendingIntent.FLAG_ONE_SHOT);
        Uri defaultSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

        OreoNotification oreoNotification = new OreoNotification(this);
        Notification.Builder builder = oreoNotification.getOreoNotification(title, body, pendingIntent,
                defaultSound, icon);

        int i = 0;
        if (j > 0){
            i = j;
        }

        oreoNotification.getManager().notify(i, builder.build());

    }

    private void sendNotification(RemoteMessage remoteMessage) {

        String user = remoteMessage.getData().get("user");
        String icon = remoteMessage.getData().get("icon");
        String title = remoteMessage.getData().get("title");
        String body = remoteMessage.getData().get("body");

        RemoteMessage.Notification notification = remoteMessage.getNotification();
        int j = ThreadLocalRandom.current().nextInt(1, 20000000);
        //int j = Integer.parseInt(user.replaceAll("[\\D]", ""));
        Intent intent = new Intent(this, MessageActivity.class);
        Bundle bundle = new Bundle();
        bundle.putString("userid", user);
        intent.putExtras(bundle);
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        PendingIntent pendingIntent = PendingIntent.getActivity(this, j, intent, PendingIntent.FLAG_ONE_SHOT);

        Uri defaultSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
                .setSmallIcon(Integer.parseInt(icon))
                .setContentTitle(title)
                .setContentText(body)
                .setAutoCancel(true)
                .setSound(defaultSound)
                .setContentIntent(pendingIntent);
        NotificationManager noti = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);

        int i = 0;
        if (j > 0){
            i = j;
        }

        noti.notify(i, builder.build());
    }
}
