I've gotten a few of these as well (and I think a discussion on this came up after the Developer Console starting show bug reports). AFAICT, the installation process sometimes leaves the app in a corrupt state leading to weird errors like this. Don't think there's much you can do about it. - TreKing http://sites.google.com/site/rezmobileapps/treking - Chicago transit tracking app for Android-powered devices -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Unable to instantiate activity...ClassNotFoundException
My app has about 100,000 downloads and the following error is being
reported in my market console a few times a week (i.e. it's a rare but
consistent problem):
java.lang.RuntimeException: Unable to instantiate activity
ComponentInfo{com.spacer.test/com.spacer.test.MainActivity}:
java.lang.ClassNotFoundException: com.spacer.test.MainActivity in

As no users have contacted me about when and where this problem arises
I have very little go on. I've tested my app on about 10 hardware
devices though and I cannot replicate this problem. My app only has
two activities and I can launch them both just fine. I've only ever
seen errors like the above when I've put the wrong class names in my
manifest files.
Does anyone have any hints about what could cause the above?
