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?
