In this chapter, we have seen how we can utilize the Firebase real-time database as a chatting medium. We assembled a straightforward messaging application that can send a reply from a wear device. There is ample space to this project to enhance the elements of the project. We have seen how a chatting application can send and receive messages crosswise over wear and handheld devices. We have conceptualised a chatting application from scratch and we have set Data Layer events for the nodes to communicate with each other. The basic idea of Messaging API is to strengthen our understanding of wearable communication. Also the GoogleApiClient class plays a noteworthy part in Play services.
In the next chapter, we will understand notifications, Firebase functions, and how push notifications can be triggered using Firebase functions.
