title: Using Google APIs in Android app with more than one developer / machine
body: <p>I'm writing an Android app with three other developers (for a school project) that makes use of various Google APIs. I set up my SHA1 key in the Developer Console  with the correct package name and I can access the APIs just fine from the app when it's launched through my Android Studio.</p>
  
  <p>Now, my teammates are trying to get their local copies to work that they just pulled from our repo and the APIs aren't working (403 and SIGN_UP_REQUIRED errors).</p>
  
  <p>What's the right way to set up their app so that they can run and test locally? And will I run into similar issues with the release-apk of the app?</p>
