조각을 만들면 응용 프로그램이 손상됩니다.

Question

좋아요, Google API 장소로 작업하고 있습니다. XML 파일에 조각 요소를 만들어야합니다. 내가 만든 프래그먼트 요소로 인해 내 응용 프로그램이 중단됩니다. 새 프로젝트에서 Fragment 요소를 시도했기 때문에 동일한 자바 코드가 아니라고 확신합니다. 같은 일이 발생했습니다. 여기 여기

import android.support.v4.app.Fragment; 

, 당신과 같은 앱이 더 문제가 있음을 seens Logcat에서 볼 수 있습니다.

어쨌든 Logcat을주의 깊게 읽으려고하면 충돌의 원인에 대해 많은 힌트가 있습니다. 내가 한 것처럼 특정 부분을 격리하고 Google에서 검색해보십시오.
