3 가지 클래스로 앱을 구분했습니다. 사용자가 사용할 기능을 선택할 수있는 기본 클래스 지도 기능은 정상적으로 작동하지만 내 길 찾기 기능은 사용자가 버튼을 클릭 할 때 강제로 닫히지 않으면 레이아웃과 관련이 있다고 생각합니다.새로운 의도가 강제 종료를 만듭니다.

어떻게하면됩니까? 감사! 이클립스 btw 사용하여 메신저! –
일식에는 logcat가 있습니다. 창을 사용하는 경우 Window-> Showview-> Logcat에서 logcat을 찾을 수 있습니다. 오류 라인이있을 것입니다. 스택 추적으로 게시 할 필요가있는 것입니다. – blessenm
