Class extending Application throws ClassNotFoundException

Question

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

java.lang.RuntimeException: Unable to instantiate application ecm2.android.ActiveStore: java.lang.ClassNotFoundException: ecm2.android.ActiveStore

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

Answer 1

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
