title: android: Writing to firebase database success from application flavor but failed with the other
body: <p>I have an application with 2 flavors full &amp; demo ... i had connected the demo version to a firebase database and works well.
  To add the second flavor I did the following:</p>
  
  <ol>
  <li><p>I added the flavor to the project and saved its SHA1.</p></li>
  <li><p>I downloaded the JSON file and but it in the app directory.</p></li>
  <li><p>Rebuilt the android project.</p></li>
  <li><p>OAuth 2.0 client key was automatically generated in the Credentials. </p></li>
  </ol>
  
  <p>Now the first flavor can read and write to the database but the second dose not.
  Is there any additional steps to do?</p>
