RuntimeException : Didn't find class on path: DexPathList

Question

Yesterday everything worked fine with my project, but today I receive very weird errors :

java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{com.example.redonbas/com.example.redonbas.MainActivity}: java.lang.ClassNotFoundException: Didn't find class "com.example.redonbas.MainActivity" on path: DexPathList[[zip file "/data/app/com.example.redonbas-2.apk"],nativeLibraryDirectories=[/data/app-lib/com.example.redonbas-2, /vendor/lib, /system/lib]]

My AndroidManifest :

<activity
    android:name=".MainActivity"
    android:label="@string/app_name" >
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>

MainActivity is in correct package:

I refered to the problem but I copied all the File System of the project to the new, but that didn't help. I also created new project with another package and manually copied all the stuff from the old project there - the problem still remains!

What's wrong with it?

是的，问题出在过去的SherlockActionBar及其android-support库中。
