구글번역과 관련된 어플리케이션을 개발중인데

구글번역 api키까지 구입하였습니다.

그후 보통의 예제소스처럼 구현하고 실행해보았는데

 //GoogleAPI.setHttpReferrer("localhost");

        //GoogleAPI.setKey("AIzaSyC4s61wFtYrV0kjNQDSg33gM"); // 키는 가짜입니다.

이 코드만 주석제거하면 프로그램이 폭발하네요

에러내용도 콘솔에서는 

[2012-11-06 22:59:37 - Emulator] emulator: WARNING: Could not initialize OpenglES emulation, using software renderer.

[2012-11-06 22:59:37 - Emulator] could not get wglGetExtensionsStringARB

로그캣에서는 다음과 같이
