에러가 이렇게 뜹니다. 이전까지 실행이 되다가 갑자기 이러네요.

 

메니패스트 에는

 <activity android:name=".Main" />
  <activity android:name=".EditPreferences"/>
  <activity android:name=".AccRecord" />

이렇게 인텐트하는 액티비티가 모두 정의되어있고.

 

 

 이게 xml 부분입니다.

 <?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/tabhost"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
    <LinearLayout
        android:orientation="vertical"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent">
        
         <TabWidget
            android:id="@android:id/tabs"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"             
            />          
        
<FrameLayout
    android:id="@android:id/tabcontent"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    >         
  </FrameLayout> 
 
    </LinearLayout>
</TabHost>

어떻게 해야될지 모르겠습니다.
