title: Do I need to call Crashlytics.start multiple times?
body: <p>I've just added my app on <a href="https://fabric.io/kits/android/crashlytics/summary" rel="nofollow noreferrer">Crashlytics</a>. I put the API key in the AndroidManifest.xml file and I call <code>Crashlytics.start(this)</code> inside of the <code>onCreate()</code> method of my launcher <code>Activity</code>.</p>
  
  <p>I've got +20 Activities and 20 Fragments. </p>
  
  <p>Do I need to put <code>Crashlytics.start(this)</code> in every Activity's <code>onCreate()</code> method in order to make Crashlytics able to track whole my app?</p>
