title: Re-installation failed due to different application signatures
body: <p>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.</p>

  <p><strong>The weirdest thing is this happened after I upgraded sdk/adt and Eclipse to support SDK 2.2</strong> It was working fine earlier, and now it doesn't, so it might be a bug.</p>
