title: Google maps api - Signature not valid
body: <p>I have an Android app that uses Google Maps. But, when I am running the app I get the following warnign:</p>
  
  <blockquote>
    <p>V/GoogleSignatureVerifier: com.google.android.gms signature not valid</p>
  </blockquote>
  
  <p>I think it is related to the debug.keystore file, but I am not sure. Do you have any suggestions on how to give it a valid signature?</p>
