Answer 1

확인합니다.

두 개의 Google API 라이브러리가 Google API 폴더를 표시하지 않아도 참조되는 중입니다. 나는 내가 그것을 사용하고있는 응용 프로그램을 만든 후에 내가 Google지도 플러그인을 설치했기 때문에 이것이 일어 났음이 틀림 없다.

해결책은 "빌드 경로 구성"에서 "maps.jar"에 대한 참조를 제거한 다음 새 Android 프로젝트를 만들고 Google API 폴더를 현재 프로젝트에 복사하여 붙여 넣기 만하면됩니다.

어쨌든 고맙습니다 ...

Answer 2

당신은 Manifest 파일> < 응용 프로그램 내에서 태그를

<uses-library android:name="com.google.android.maps" /> 

을 추가 했습니까?
