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 . infront of the class name. It seems to only happen on an update or new install

Class ClassNotFoundException. Thrown when an application tries to load in a class through its string name using: The forName method in class Class . The findSystemClass method in class ClassLoader .
ClassNotFoundException is a checked exception which occurs when an application tries to load a class through its fully-qualified name and can not find its definition on the classpath. This occurs mainly when trying to load classes using Class. forName(), ClassLoader. loadClass() or ClassLoader.
click on project->properties->Java build path->Source and check each src folder is still valid exist or recently removed. Correct any missing path or incorrect path and rebuild and run the test. It will fix the problem.
Probably because you're missing the dot in front of the class name (which helps to tell Dalvik that your class belongs to the package of your app)
.ActiveStore
But if in doubt, post both the whole Manifest file and your .java
