Google Cloud Messaging for Android (GCM) is a service that allows you to send data
|
|
from your server to your users' Android-powered device. This could be a lightweight
|
|
message telling your app there is new data to be fetched from the
|
|
server (for instance, a movie uploaded by a friend), or it could be a message containing
|
|
up to 4kb of payload data (so apps like instant messaging can consume the message directly).

|
The GCM service handles all aspects of queueing of messages and delivery to the target Android
|
|
application running on the target device.
|
|
GCM is completely free no matter how big your messaging needs are, and there are no quotas.</p>
