안드로이드 프로젝트에서 연락처를 추가하거나 새로운 활동을 시작하려고 할 때 버튼이 제대로 작동하지만 SMS를 보내려고하면 강제 종료됩니다. 위의 코드에서 sendsms활동간에 데이터를 전달하면 강제로 닫기가 발생합니다.

코드를 지우고 관련된 내용 만 표시하십시오. 그런 다음 @WebnetMobile이 제안한대로 LogCat에서 스택 추적을 표시합니다. – coder
의도적으로 반환 된 널 포인터 예외로 인해 오류가 발생했습니다. 처리해야합니다. send sms는 ininitialised 변수 때문에 강제 종료되었습니다. 나는 그 부분을 바로 잡았습니다. – sid
