如何解决后台uid UidRecord中的不允许启动服务应用程序？

Question

我正在测试该应用程序，并测试Firebase通知，该通知过程在Android 6.0版中工作正常，而在8.0中测试该应用程序时，通知过程不起作用。

错误

Firebase页面

    package com.progressive_solution.parttimeforce;

import android.content.SharedPreferences;
import com.google.firebase.messaging.RemoteMessage;

public class FirebaseMessagingService extends com.google.firebase.messaging.FirebaseMessagingService

        startFloatingWidgetService();
    }

    private void startFloatingWidgetService()
    {
        startService(new Intent(FirebaseMessagingService.this, FloatingWidgetService.class));

    }
}

在此页面中出错。

我尝试使用startForeground，但显示无效的频道错误。
