App Won't Install After Package Rename

In order to easily test some features I created a stripped down copy of my app. Unfortunately neither of the applications seem to run any more. I have changed the package name for

Solution 1:

Got it. Turns out that the eclipse refractor renamed the android:name attribute in the manifest to contain the package name aswell as the launch activity. Not sure why the older version wasn't installing but it seems to be fine now ^^

Most likely, you just need to remove the original package from the device/emulator.

I've had the same problem in the past and removing my 'working' app from the emulator allowed for the renamed app to install and run properly.

Edit: more info on how to remove a package: http://androidcommunity.com/forums/f4/how-to-uninstall-delete-an-application-from-the-emulator-126/ or go to Settings -> Applications -> Manage applications and you can uninstall it from there.
