title: Differentiate crash reporting between debug and production builds
body: <p>I'm setting up Firebase Crashlytics for my Android app, and I would like the crash reports for the debug version to be separate from all other versions.</p>
  
  <p>There are several copies of the auto-generated values.xml file (that is generated when the google-services plugin processes toe <code>google-services.json</code> file) located in the different retrospective buildType folders. One of the strings contained in the files is:
      <code>&lt;string name="google_crash_reporting_api_key" translatable="false"&gt;{API-KEY}&lt;/string&gt;</code></p>
  
  <p>The API key is the same for each buildType, so I'm thinking if I can just create a new API key for the debug version, it'll solve the problem but how to do this? Or is there another way (that doesn't involve changing the applicationId as I can't do this)?</p>
  
  <p>I've searched the android docs, looked up other articles and looked through other SO answers but no luck.</p>
  
  <p>Any help welcomed, thank you.</p>
