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

After searching and checking the phone, i came to know that i am currently developing 2nd version of this application which is already downloaded from android market in my phone, now as this app is signed and having different signatures this is throwing the above error.

Now, to resolve this issue, i had just uninstalled the app from mobile and run/install the application again.
