Android: Unable to instantiate activity / ClassNotFoundException

Question

I recently published an app to the market and I\'m now getting an error by some user, the app presumably crashes right when it starts. Unfortunately I can\'t contact him dir

Answer 1

This problem might exist when you change the name of your class and update the manifest file and the manifest file is not updated on the emulator. Try uninstall the application from emulator and then reinstall it. This will work.
