Answer 1

I would try removing

android:name="MargApp" 

if that didn't work try Cleaning up your project

Project>Clean

Answer 2

Do not use the android:name attribute! It, misleadingly, does not have anything to do with the name of your app and is actually the name of an extra class to load before loading your application. That's why you are getting the ClassNotFoundException. Remove it and it should work:

Replace your application tag with this one...

<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
