title: Firebase database dependency crashes app
body: <p>I'm trying to write to my DB with the following "<a href="https://firebase.google.com/docs/database/android/start/" rel="noreferrer">Set up Firebase Realtime Database for Android</a>" example but the app crashes on startup.  </p>
  
  <p>It's seems because the dependency:</p>
  
  <pre><code> compile 'com.google.firebase:firebase-database:9.2.1'
  </code></pre>
  
  <p>The crash log:</p>
  
  <pre><code>FATAL EXCEPTION: main
