title: How I can handle the Data payload in Firebase Cloud Messaging?
body: <p>I have this code to get the notification from Firebase Messaging. How can I handle the data using key / value and show it in a Log or an EditText? </p>

          // There are two types of messages data messages and notification messages. Data messages are handled
          // here in onMessageReceived whether the app is in the foreground or background. Data messages are the type
          // traditionally used with GCM. Notification messages are only received here in onMessageReceived when the app
          // is in the foreground. When the app is in the background an automatically generated notification is displayed.
          // When the user taps on the notification they are returned to the app. Messages containing both notification
          // and data payloads are treated as notification messages. The Firebase console always sends notification
          // messages. For more see: https://firebase.google.com/docs/cloud-messaging/concept-options
