title: Recommended .gitignore for react-native
body: <p>I'm trying out react native and <code>eject</code>ed into a full build environment. Sadly, the eject-script did not create a sensible <code>.gitignore</code> file.</p>
  
  <p>Not knowing a lot about app-development, I wonder what directories I could <code>.gitignore</code> here?</p>
  
  <p>I'm guessing:</p>
  
  <ul>
  <li><code>android/build</code></li>
  <li><code>android/app/build</code></li>
  <li><code>android/.gradle/</code></li>
  </ul>
  
  <p>Are these alright, or are there any more directories I should <code>.gitignore</code>?</p>
