title: Firebase console: How to specify click_action for notifications
body: <p>I implemented Firebase and testing the Firebase notifications.
  When the app is in the foreground I don't have problems, I implemented a service that extends <em>FirebaseMessagingService</em> and handle the message and data in <em>onMessageReceived</em></p>
  
  <p>I have problems when the app is in background, I would like to send a notification that opens a specific activity and does what I schedule to do, not just opening the App.</p>
  
  <p>I did as described on the Firebase guide, but I'm not able to start the specific activity.</p>
  
  <p>Here the manifest:</p>
  
  <pre><code>&lt;activity android:name=".BasicNotificationActivity"&gt;
              &lt;intent-filter&gt;
                  &lt;action android:name="OPEN_ACTIVITY_1" /&gt;
                  &lt;category android:name="android.intent.category.DEFAULT" /&gt;
              &lt;/intent-filter&gt;
          &lt;/activity&gt;
  </code></pre>
  
  <p>And here the Firebase Console. What do I have to write in those fields to open my "BasicNotificationActivity"?</p>
