update:

first of remove part:

<activity android:name="slider.example.fragment0" android:theme="@android:style/theme.notitlebar" android:screenorientation="portrait" /> <activity android:name="slider.example.fragment1" android:theme="@android:style/theme.notitlebar" android:screenorientation="portrait" /> <activity android:name="slider.example.fragment2" android:theme="@android:style/theme.notitlebar" android:screenorientation="portrait" /> <activity android:name=".mypageradapter"></activity> 

not fragments or adapter not activities , shouldn't write them manifest file.

and try change part:

<activity android:name="slider.example.viewpagerfragmentactivity"               android:label="@string/app_name">         <intent-filter>             <action android:name="android.intent.action.main" />             <category android:name="android.intent.category.launcher" />         </intent-filter>     </activity> 

to this:

<activity android:name=".viewpagerfragmentactivity"               android:label="@string/app_name">         <intent-filter>             <action android:name="android.intent.action.main" />             <category android:name="android.intent.category.launcher" />         </intent-filter>     </activity>
