Android: Re-installation failed due to different application signatures

Frequently we do our work from two different computers, for example at work and at home. You will get this error and ask you to re install your app.

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 )
