title: Cannot find where to execute "gradle assembleRelease" on Windows
body: <p>I am trying to sign my apk for release. In eclipse I could just go File->Export, type in my credentials and be good to go.</p>
  
  <p>In Android Studio I read you have to execute the "gradle assembleRelease" command after setting up the gradle script.</p>
  
  <p>I just can't figure out where to run this command? The Windows console does not recognize it, "where gradle" comes up empty aswell and I can only find a gradle.jar file that does not get executed in the console.</p>
  
  <p>I just want to sign my apk for realease.</p>
