Android 8.0 啟動后臺service 出錯 IllegalStateException: Not allowed to start service Intent

錯誤原因：
Android 8.0 不再允許后臺service直接通過startService方式去啟動。

解決辦法：

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        context.startForegroundService(new Intent(context, ServedService.class));
    } else {
        context.startService(new Intent(context, ServedService.class));
    }
And in service class, please add the code below for notification:

@Override
public void onCreate() {
    super.onCreate();
    startForeground(1,new Notification());
}
