당신은 당신의 Activitys에서 onCreate 방법 becase NullPointer 예외를 점점 더 된 setContentView이 없습니다 (R.layout.yourlayout) 요구. 이렇게 하시겠습니까?

@Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.yourlayout) 

     // your other stuff 
    }
