이 코드가 잠기는 이유를 찾는 데 어려움을 겪고 있습니다. 내가 아는 한, 아래에 표시된대로 내 매니페스트 파일에서 올바른 사용 권한을 선언하고 있습니다. 나는 실제 장치 (Droid x w./2.3.3)와 AVD를 사용하지 않으려 고 노력했다. 나는 logcat을 첨부하여 classnotfound 예외 상황에 빠지게했다. 프로젝트를 정리하고 maps.jar이 googleapi의 패키지에 포함되어 있는지 확인했습니다.이 패키지는 응용 프로그램의 대상으로도 사용되었습니다. (Google API 2.3.3). 여기에서 어디로 가야할지 모르겠다.ClassNotFoundException MapView를 사용하여 던졌습니다.
