Android App crashing on navigating from one Screen to another on Device but working fine on the Emulator.?

When I had a device specific problem, I installed the log collector app to the device: a href="http://code.google.com/p/android-log-collector/downloads/list." rel="nofollow"http://code.google.com/p/android-log-col…/a Then, I added some logging to the app where the problem was, ran the app on the device until it crashed, then ran log collector which emails you the log. I was able to see the stacktrace and eventually solve the problem. Good luck.
