Chatting Application Using Google Cloud Messaging

Abstract— Chatting Application Using Google Cloud Messaging. Google Cloud Messaging < Final Year Projects 2016 > GCM is a free service that enables users to send messages between servers and client apps. This includes downstream messages from servers to client apps, and upstream messages from client apps to servers. For example, a lightweight downstream message could inform a client app that there is new data to be fetched from the server, as in the case of a “new email” notification. For use cases such as instant messaging, a GCM message can transfer up to 4kb of payload to the client app. The GCM service handles all aspects of queuing of messages and delivery to and from the target client app. A GCM implementation includes a Google connection server, an app server in your environment that interacts with the connection server via HTTP or XMPP protocol, and a client app. Google GCM Connection Servers take messages from your app server and send them to a client app.
