title: Changing android signing key password
body: <p>Does anybody know how (and if) you can change the password used to sign android builds?</p>
  
  <p>We have a live app, but want to change the signing password. The problem is that we don't want to force our users to reinstall the app (if we use a new key users won't be able to install the new build as an update to the original app).</p>
  
  <p>I've looked all over the android documentation, but have been unable to find anything even related to the subject (except for making a new key...).</p>
