원인이 뭘까요..... 소스엔 에러가 없는데 실행이 안됩니다 ㅠㅠ

이 게시물을

dingpong

우선 공지사항 먼저 보시고..질문을 올려주세요.
어디서 문제가 났는지는 올려주신 logcat 에 보면 소스코드랑 라인까지 찍힙니다.
거기에 브레이크 포인터 걸고 디버깅 모드로 실행해서 왜 에러가 났는지 보시면 됩니다..
보니까 ClassCastException 이 많이 보이는데, 형변환을 못하는 것을 강제로 시킨게 아닐까 싶기도 하네요.

그냥가자

이것도 메니피스트 같은 느낌인데요....
my.honam.Datamanager/my.honam.Datamanager.ContentProviderTest
메니피스트 등록하실때 Pakage를 my.honam.Datamanager로 주셨으니까
".ContentProviderTest" 형태로만 쓰시면 됩니다.

<activity android:name=".ContentProviderTest"
이부분 때문이군요...

ContentProviderTest는 ContentProvider이지 Activity가 아닌데요...
