내 Android 애플리케이션에 Google Map V2를 구현 중입니다. 나는이 두 링크의 모든 단계를 완료했다. http://www.androidhive.info/2013/08/android-working-with-google-maps-v2/http://developer.android.com/google/play-services/setup.html 이렇게 답을 보내지 마라. Maps API를 다운로드하고, Eclipse Workspace에 복사하고, 라이브러리로 표시하고, 내 프로젝트에서 참조했다. 그러나 성공하지 못했습니다. 나는 아직도 오류가 발생하고있다. 누군가 나를 기쁘게 할 수 있을까? 감탄 해야겠다. 여기에 활동 코드가Android에서 Google지도 V2를 사용할 수없는 이유는 무엇입니까?
