title: Unresolved class 'MyFirebaseMessagingService'
body: <p>I'm following the tutorial on <a href="https://firebase.google.com/docs/cloud-messaging/android/client#manifest" rel="nofollow noreferrer">Setting up a Firebase Cloud Messaging client app on Android</a> which involves adding a <code>&lt;service&gt;</code> component to <code>AndroidManifest.xml</code>. </p>
  
  <pre><code>&lt;service android:name=".java.MyFirebaseMessagingService"&gt;
      &lt;intent-filter&gt;
          &lt;action android:name="com.google.firebase.MESSAGING_EVENT" /&gt;
      &lt;/intent-filter&gt;
  &lt;/service&gt;
  </code></pre>
  
  <p>However, I'm getting <code>Unresolved class MyFirebaseMessagingService</code>. Where exactly do I import that class from?</p>
  
  <p>NOTE: I'm writing in Kotlin</p>
