"Force close" error when running app

[amir1]

Hello,

I'm trying to use explicit intents (invoking an Activity by another Activity) in Android 2.2 but each time i click on a button in order to invoke another activity i get the following message:
"Sorry! The application [app name] has stopped unexpectedly. Please try again".
and I have a button of "Force close".

Does anyone know how to solve this problem?

Thanks.

I'd always suggest as a 1st step in troubleshooting FC's that you clear cache and data for the FC'ing app.
