활동에서 서비스를 시작하려고 시도했지만 단추를 클릭하여 호출하면 시뮬레이터가 내 응용 프로그램을 중지하고 "응용 프로그램 (...)이 예기치 않게 중지되었습니다. 다시 시도하십시오." 내 매니페스트에서서비스 시작시 응용 프로그램이 작동을 멈 춥니 다.

TimerGuardActivity의 39 번째 줄에는 무엇이 있습니까? (또는 전체 코드를 게시하는 것이 더 좋습니다). 이것은 널 포인터가 명백하게 나오는 곳입니다. – Teovald
TimerGuardActivity를 표시하고 문제가있는 곳의 logcat에 오류가 있으면 알려주십시오. –
