title: Google Maps API Key in release build doesn't work
body: <p>I'm currently developing an application for Android and I'm using Google Maps API. In developer console, I added my SHA1 certificate print, followed by my package name.
  Even though I put this SHA1 certificate print using keytool, I can't access to the maps.
  I made lots of search, but every topics brought me to answers where error were in a wrong API Key in developer console.
  But I took the right SHA1, the one of my certificate.</p>
  
  <p>Thanks in advance !</p>
