Re-installation failed due to different application signatures

Question

I moved my Android project to a laptop and now I get this when I hit Debug. Sounds like this is a bug? This shouldn\'t happen via Eclipse as far as I know.

Answer 1

It happens because keystores on your laptop and original pc are different. it's called debug.keystrore and located in %USER_HOME%/.android/ folder. TO be more specific it happens because eclipse tries to push apk with reinstall key. So you have two options

1. Share debug.keystore between various development pc's
2. Manually uninstall your apk from device ( using adb )
