title: Firebase Crashlytics Build Secret for Fastlane
body: <p>I'm attempting to use Fastlane to automate an Android build, including Crashlytics.</p>
  
  <p>My Fastfile includes:</p>
  
  <pre><code>  lane :deploy do
      gradle(task: "clean assembleRelease")
      crashlytics(api_token: "my-token")
      upload_to_play_store(track: "internal")
    end
  </code></pre>
  
  <p>When I invoke <code>fastlane deploy</code>, it stops at the Crashlytics step and prompts: </p>
  
  <pre><code>    [06:57:27]: -------------------------
      [06:57:27]: --- Step: crashlytics ---
      [06:57:27]: -------------------------
      [06:57:27]: To not be asked about this value, you         can specify it using 'build_secret'
      [06:57:27]: Crashlytics Build Secret: 
  </code></pre>
  
  <p>I'm trying to figure out where to get the build secret from the Firebase Crashlytics console. I don't see it there.</p>
  
  <p>Where do I find the build secret for Firebase Crashlytics?</p>
