title: Click on notification not launching the app
body: <p>When push notification is received while the app is not running and the user presses on notification, it just disappears and the log says:</p>
  
  <pre><code>2019-10-22 12:42:45.747 23260-23260/de.app.test.staging E/FirebaseMessaging: Notification pending intent canceled
  </code></pre>
  
  <p>Here is the SplashActivity that is supposed to be launched as a Launcher Activity:</p>
  
  <pre><code>    &lt;activity
          android:name="de.app.test.login.SplashActivity"
          android:screenOrientation="portrait"
          android:exported="true"
          android:theme="@style/Theme.AppCompat.Light.NoActionBar.FullScreen"&gt;
          &lt;intent-filter&gt;
              &lt;action android:name="android.intent.action.MAIN" /&gt;
  
              &lt;category android:name="android.intent.category.LAUNCHER" /&gt;
          &lt;/intent-filter&gt;
      &lt;/activity&gt;
  </code></pre>
  
  <p>What can the issue be here?</p>
