title: Losing data because of different Android signatures
body: <p>I've been using my application for a while and produced a lot of data in it. Now it came time to upgrade it but the problem is that I've bought a new laptop and I can't upgrade the application due to different signature another IDE is using. It is impossible now to save the data, right?</p>
  
  <p><strong>Update:</strong> I didn't use any .keystore intentionally, I was just installing from Eclipse.</p>
