Unable to instantiate java.lang.classnotfoundexception android

Question

I know there are a number of these already but it seems that none of them address my issue. What is weird is that this error ONLY occurs on a signed package (running it from Eclipse works perfectly) and this only popped up with my most recent update that I published (but I can't think of anything relevant that I changed...)

Caused by: java.lang.ClassNotFoundException: com.domain.app.MainApp

I have use a class that extends Application in order to use a library. The applicable manifest portion looks like this:

<application android:icon="@drawable/launcher" android:label="@string/app_name"
    android:theme="@style/MyTheme" android:name=".MainApp">

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

    </activity>

Anyone know what could be causing it?

Not sure what was wrong but after cleaning, re-exporting, and re-uploading the problem stopped occurring.
