startactity에서 인탠트로 다른 Display activity로 넘어 가는건데

일단 오류는 이겁니다.

 

근데 문제는 메니페스트에 엑티비티를 등록 했음에도 불구하고 저런 애러가 뜬다는 겁니다...

 

 

        <activity
            android:name=".DispalyActivity"
            android:label="@string/app_name" >
        </activity>

 

 

그러다가 문제가 될 만한점이... 맞는가 싶긴 한데

DisplayActivity는 extends가 Activity가 아닌  FragmentActivity 라는 점입니다.

 

음... 어떻게 해야하나요
