Create Firebase Messaging Service

Let's add the code to process data messages. To do this, you'll need to create a FirebaseMessagingService. Follow the TODOs in the code to complete this exercise. Once you're done, you should be able to send a Squawk to a Single Device from the Squawker server. Remember that you'll need your server key, which you can get from the Firebase Console as shown in this video.

If you need it, here's an example of getting data from a RemoteMessage object:

java Map<String, String> data = remoteMessage.getData(); String author = data.get("author");

Part of this exercise involves interacting with content providers and creating a notification. These are two topics we've covered previously. If you're not familiar with these concepts you can learn more about notifications here and interacting with content providers here.
