I have a class that extends the application class and sometimes in my developer console I see an error saying ClassNotFoundException

This is how I declare it in my manifest

<application
    android:name=".ActiveStore"
    android:icon="@drawable/icon"
    android:label="@string/app_name"
    android:theme="@android:style/Theme.NoTitleBar" >

ActiveStore is just a class that holds an application context to start and cancel alrams so why would I get this error?

Update:

I am still seeing this error from time to time in my developer page even after putting a .
