백그라운드에서 음악을 재생하는 미디어 플레이어 서비스가 있으며이 서비스는 활동에서 호출됩니다. 이제 내가 전.서비스에서 mediaplayer 서비스 화면 가져 오기

그리고 내 활동 코드 : 그 활동을 종료하고 다시 그것을 얻을, 나는 어떤 노래가 재생되는 상태 등이 여기에
내 서비스에서 코드입니다 무엇인지보고 싶어 - onClick :case R.id.playeer_play:
playbackServiceIntent
.putExtra("url", songs.get(position).getLink());
playbackServiceIntent
.putExtra("position", position);
startService(playbackServiceIntent);
break;
무엇이 질문입니까? – CommonsWare
@CommonsWare 죄송합니다. 불명확하면 서비스를 통해 노래를 재생합니다. 지금 전. 내가 그 활동에서 벗어나서 검색 바에서 돌아올 때, 위치, 노래 이름 등 정보가 손실됩니다. 어떻게 든 플레이어 화면으로 돌아 가면 모든 데이터가 거기에 있도록 참조해야합니다. –
저의 요점은 질문이 아닙니다. 암묵적인 질문은 "어떻게합니까?", 무엇을 시도 했습니까? 그리고 어떤 특정 문제가 발생 했습니까? – CommonsWare
