title: Detecting debug keystore or release keystore programmatically
body: <p>I was wondering if there was a way to detect if the program is running on the default (debug) keystore (when running from eclipse) or on a signed keystore (when released to Android market)</p>
  
  <p>I use Google Maps in my application and I would like programmatically change the Maps API key appropriately for testing and release since the one API key only works for either testing or 
  release.</p>
  
  <p>There must be a way to do this since Google Maps can detect what keystore was used to compile the application (to enable or disable the maps).</p>
