Error message: ' ... ' is not assignable to Android.app.Activity Manifest XML

1 Problem Description:

For this piece of code:

<activity android:name= ". Fragament.fragment_bulter"/>
<activity android:name= ". Fragament.fragment_girl"/>
<activity android:name= ". Fragament.fragment_user"/>
<activity android:name= ". Fragament.fragment_wechat" >

</activity>

AndroidManifest.xml 中出现提示：‘com.example.cheung.……‘ is not assignable to Android.app.Activity Manifest XML   

Workaround:

returning to view the Fragment_bulter,fragment_girl,fragment_user,fragment_wechat function definition is actually inherited by fragment, which means that The code actually adds fragment to the activity, which naturally makes an error.

Workaround one: To retain several functions for fragment ，则 theAndroidManifest.xml中直接删掉这段即可

Workaround two: To AndroidManifest.xml retain several functions as activity, the

public class Fragment_bulter extends fragment{...}
Switch

fragmentactivity {......}

Result: Resolved
