Android에서 YouTube Data Api 사용

Question

내 Android 앱에서 YouTube Data API를 사용하려고합니다. Java 프로젝트로 실행하려고하면 오류없이 정상적으로 실행됩니다. 그러나 내 안드로이드 응용 프로그램에서 동일한 일을하려고하면 응용 프로그램 강제 종료합니다. 다음은 logcat과 내 코드의 출력입니다. 로그 캣 HERE

이전에 Youtube Data API를 지원하지 않았지만 v3이 릴리스 된 google-api-java-client (gdata-client와는 달리 안드로이드 지원)는 이제 수정되었습니다. 지금 당신에게 필요한 것을 제공해야하는이 클라이언트와 함께 좋은 유튜브 지원이 있습니다. 자세한 내용 및 코드 샘플 여기를 참조하십시오 :
