title: Firebase authentication network error on Android using Ionic app
body: <p>I have Ionic2 app running well on windows chrome. I am using Firebase.
  When running on Android emulator I am getting a network error: </p>
  
  <pre><code>A network error (such as timeout, interrupted connection or unreachable host) has occurred.
  </code></pre>
  
  <p>I tried few suggestions with no success:  </p>
  
  <ul>
  <li>I changed the button from submit type to button type  </li>
  <li>I checked the whitelist  </li>
  <li>I removed the usage of a form.  </li>
  </ul>
  
  <p>Nothing worked.</p>
  
  <p>Is there anything I should configure in Firebase before running the web app on Android?</p>
