title: How to update Google Play Signed Apk from other than play-store (website etc)
body: <p>I uploaded an <em>apk</em> signed with my keystore to Google play with accidentally enabling <strong>Google App Signing</strong> option.
  I have same <em>apk</em> uploaded at my website.</p>
  
  <p>Now, Due to <strong>Google App Signing</strong> option, both <em>apks</em> have different signature</p>
  
  <ol>
  <li><em>Google Play Apk</em> : Signed by Google</li>
  <li><em>Website Apk</em> : Signed by my key</li>
  </ol>
  
  <p>which is causing <a href="https://stackoverflow.com/questions/4843212/the-apk-must-be-signed-with-the-same-certificates-as-the-previous-version">The apk must be signed with the same certificates as the previous version error</a> on update.</p>
  
  <p><strong>Q) How can I make my Website-apk signed with same signature as Google-Play-signed-apk?</strong></p>
