GCM Server Helper

GCM Server Helper is intended to ease the server-side integration with Google Cloud Messaging (GCM).

Prerequisites:
- Create a project on you android dev console
- Enable the GCM API from the project console
- Generate a key for server applications

Instructions:
1. Enter your project number
2. Hit the register button
3. Send the assigned GCM registration id by email to you server\'s developer workstation
4. On the server side, send an HTTP POST message to https://android.googleapis.com/gcm/send with the following characteristics:
http headers: Content-Type: application/json, Authorization: key=XXXXXX
http body: {
"registration_ids":["YYYYYY"],
"delay_while_idle":true,
"data" :
{ "whatever_field_you_want":"whatever_data_you_want"
}
}
where XXXXXX=your_server_api_key and YYYYYY=your_gcm_registration_id
5. Your mobile should vibrate and either show you a notification or display the received GCM message in the app if opened.
