Hello, i have an app on market and i sometimes get this crash report
I think the app just doesn't start on some devices
The app link is:
https://play.google.com/store/apps/details?id=aithanasakis.anekdota

java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{aithanasakis.anekdota/aithanasakis.anekdota.main}: java.lang.ClassNotFoundException: aithanasakis.anekdota.main in loader dalvik.system.PathClassLoader[/mnt/asec/aithanasakis.anekdota-1/pkg.apk]

I'm currently working on an update so any help to find what's causing it would be greatly appreciated!

This error might happen if the user has installed the app to the sd card and later removed the sd card.

Search Google for this error message. You will see that many developers encountered this somewhat strange issue.
