현재 gcm을 이용하여 어플 개발중인데 GCMRegistrar.register여기서 자꾸 에러가 걸립니다.

어플을 다운로드 후 처음 실행시 regId값을 받지 못하고 종료 후 다시 실행해보면 regID값을 받아 옵니다. 

도대체 뭐가 문제인지 정말 모르겠네요.... 좀 알려주세요...ㅠㅠ

정말 이거 때문에 미치겠네요.... 벌써 이것때문에 몇시간째 헤매고 있는 건지..ㅠㅠ 고수님들 해결법 좀 알려주세요...ㅠㅠ

============== 소스 부분 ==================

private void registGCM() {

GCMRegistrar.checkDevice(this);

//Checks if the device has the proper dependencies installed.

//단말이 GCM을 지원하는지 검사

GCMRegistrar.checkManifest(this);

//Checks that the application manifest is properly configured.

//응용프로그램의 매니페스트가 제대로 구성되어 있는 지 확인

final String regId = GCMRegistrar.getRegistrationId(this);

//Gets the current registration id for application on GCM service.

//GCM서비스의 응용프로그램에 대한 현재 등록 ID를 가져옴.

if("".equals(regId))   //구글 가이드에는 regId.equals("")로 되어 있는데 Exception을 피하기 위해 수정

GCMRegistrar.register(this, GCMIntentService.SEND_ID); <--- 여기서 에러가 걸립니다.

//Initiate messaging registration for the current application.

//현재 응용 프로그램에 메시징 등록을 시작

else

tv.setText(regId);

Log.d("==============", regId);

    }
