For no reson my Android app stopped running.?

Question

My app has been working fine the whole time I've been developing it, but it suddenly stopped working. It crashes right at the begining even before opening. The same thing happens on the phone or on the emulator. I went back a few versions that used to work as well, and they aren't working.

Could this be something to do with the android.jar??

Here is the LogCat:

Your exception is a ClassNotFoundException. Eclipse should not compile, if the class is internal to your application. Maybe some external references broken?

You're right. This was a screw up on my end. I accidental clicked on something while trying to figure out another thing, and somehow all my java file replaced my xml files in the layout folder. Long story short, everything now works. Thanks for the help. – Zolt Apr 11 '12 at 18:14
