title: New SHA1-key for Google Maps V2
body: <p>I used debug SHA1-key for testing in-App purchases in Google Play. But with debug key not working Google Maps V2, I only see a gray screen instead of cards. I generated the release key, build new apk file and now i can`t upload this file to Google Play.</p>
  
  <pre><code>Upload failed You uploaded an APK that is signed with a different certificate to your previous APKs. You must use the same certificate. Your existing APKs are signed with the certificate(s) with fingerprint(s):
  SHA1: XX:XX:XX..XX
  and the certificate(s) used to sign the APK you uploaded have fingerprint(s):
  SHA1: YY::YY:YY…YY
  </code></pre>
  
  <p>Does anyone have any idea how to do in this situation?</p>
