title: Get user information in Crashlytics
body: <p>I am using Crashlytics in my application and I wanted to get user id and email along with each crash. I did something like this:</p>
  
  <pre><code>Crashlytics.setUserEmail(tokenModel.getEmail());
  Crashlytics.setUserIdentifier(String.valueOf(tokenModel.getPk()));
  </code></pre>
  
  <p>I am doing this in my login screen, after the user has provided his email and successfully registered with the app, so as to get user id. The problem is, I am not getting these data in the crash reports.</p>
  
  <p>What is the lifecycle and working of Crashlytics in above context? Do I need to set these fields every time the app opens?</p>
