targetSdkVersion을  28로 올렸다.
그리하였더니 권한 오류가 발생하였다. 
포그라운드 서비스를 이용하려면 FOREGROUND_SERVICE 권한을 요청해야한다.

동작 변경사항: API 레벨 28+를 대상으로 하는 앱

Android 9 이상을 대상으로 하고 포그라운드 서비스를 사용하는 앱은 FOREGROUND_SERVICE 권한을 요청해야 합니다. 이 권한은 정상 권한이므로, 시스템은 요청 앱에 자동으로 권한을 부여합니다.

Manifest 파일에 추가하면된다.
<uses-permission android:name=“android.permission.FOREGROUND_SERVICE” />
