알람 앱이 제대로 작동하지 않음

Question

알람 앱을 만들면 선택한 사운드가 재생되고 알람이 설정된 시간을 알려주는 알람 앱이 생성됩니다.

필자는 결코 사운드를 얻지 못한다. 여기에 내가 누락 되었습니까?

편집 : AlarmReceiver

public class AlarmReceiver extends BroadcastReceiver { 

@Override

    Log.e("Goat quote is" , richard_id); 

    Intent serviceIntent = new Intent(context,RingtonePlayingService.class);

이것은 : 죄송합니다이 내가이는 MainActivity입니다

이 무엇이것은 RingtonrPlayingService

Answer 1

올바르게 MediaPlayer를 시작하지 않을 것입니다. 이를 통해

읽기, 서비스와 MediaPlayer를 사용에 특히 섹션 :

2. 을

2 단계를 건너 뛰고 2 단계에서 재생이 서비스에서 발생하는 경우 올바르게 작동하려면 약간의 작업이 필요합니다. 또한 MediaPlayer 리소스를 올바르게 관리하지 못합니다. 여기
