title: Firebase Analytics events don't show up (Android)
body: <p>I have an issue with Firebase Analytics. It basically boils down to the fact that nothing is registered; I have no data in my analytics page in the console.</p>
  
  <p>I noticed today that when I want to send a push notification and I set a filter for the version number of my app, it shows "No versions available for this app". However, my iOS version of the app IS showing a version number in the dropdown list.</p>
  
  <p>Does anyone have an idea what the issue is?</p>
  
  <p>Some other issues I'm still experiencing:</p>
  
  <ul>
  <li>"Firebase API initialization failure." IncompatibleClassChangeError ContextCompat.getNoBackupFilesDir() -> InvocationTargetException</li>
  <li>Failed to load module descriptor class: Didn't find class "com.google.android.gms.dynamite.descriptors.com.google.firebase.auth.ModuleDescriptor"</li>
  </ul>
  
  <p>Many thanks in advance.</p>
