java.lang.ClassNotFoundException on working app

by

Yep, I had this exact same problem. It was because I specified the android:name attribute in the application node in the manifest file.

Your Android Manifest file probably looks something like this:

   <application 
       android:name="Novak ESC Track guide" 
       android:icon="@drawable/icon" 
       android:label="@string/app_name" 
       android:description="@string/help_text" >

Do not use the android:name attribute! unless you’ve implemented a custom Application object.

The application:name attribute has nothing to do with the name of your app. This is the name of a specific class to load as your Application instance. That’s why you would get the ClassNotFoundException if that class wouldn’t exist.

For the name of the app use the android:label attribute on this same application node instead.

Remove it and it should work:

<application 
    android:icon="@drawable/icon" 
    android:label="@string/app_name" 
    android:description="@string/help_text" >
