The Cloud How it should work… and was explained.
Google Cloud Messaging
Downstream messaging server=>client
Thinking behind the design Clients don’t have wake up and poll the server for updates They register for notifications and then wait for the to arrive GCM is engineered to minimize the amount of time the cellular radios exchange data This is because Google Cloud Messaging (GCM) comes power
Upstream messaging client=>server
Send an upstream message client => server To initiate an upstream message, the client app sends a request containing the following: The address of the receiving app server, in the format SENDER_ID@gcm.googleapis.com. A message ID that should be unique per sender ID. The message data comprising the key/value pairs of the message's payload.
How it really works… A backend rest service via GCM google cloud messaging (deprecated) Via FCM firebase cloud messaging Added to your studio project and pushed the google systems Plus the receiver/sender on the device.
To the example This is best shown as a live demo of setup Except all my examples use the deprecated GCM, not FCM. https://firebase.google.com/docs/cloud-messaging/server https://firebase.google.com/docs/cloud-messaging/ https://firebase.google.com/docs/android/setup
