android GCM

[Kartik Sudarshan]

Hi Junta
I am a newbie to android programming in linux(Ubuntu) but I want to start developing.
I wanted to try the android Google Cloud Messaging (GCM).
I went through its details on what all is required in the android developement page
The following are my doubts.
1.What is this  "3rd-party application server" that they are mentioning about
2.How do I generate and implement this application server
3.How do I link it to the GCM server

Thanks in Advance

1) 3rd-party application server, in this case, would be a server you run/control. Like Facebook has their Android app, and they have their own servers.

This server is called "3rd-party" only because Google's own servers are in play, them being the "2nd-party".

The whole point of GCM is that your server doesn't have to have a connection open with all installations of your app just to send data to it occasionally. Imagine that happening with 10 different servers and 10 different apps for 10 corresponding services!

The thing with GCM is that Android has only one, highly optimized, connection to just one service/server: Google's. All the 10 different servers talk to GCM; GCM talks to Android, and Android talks to the corresponding app.

Each of those "10 different servers" is called a "3rd-party application server" in GCM's parlance.

2) Implementing one is very simple. You can do it any framework/language/platform of your choice, be it PHP, Rails, Python or even shell. The old/original way involves just HTTP requests. The new way, well-suited to high-volume publishing, involves XMPP connections. I think both are supported, but even if not, XMPP client libraries are mature and plenty. Look into the official docs.

3) Linking: I don't understand what exactly you mean here. If you mean sending data from 3rd-party server to Google's server, look above.

Just asking as you brought it up. Can we get data from GCM servers through our insti internet? Can android notifications (using GCM) be received while we are connect to insti internet?

Thanks in advance.

GCM uses ports 5222 & 5228. Neither is accepted by netmon.

Thank you

when I meant linking I meant how do I connect to the GCM server.
Correct me if I am wrong,the following is a setup idea if I want to use GCM :

Assume that I am running a group and I have made an app which just acts as a receiver for broadcast messages so :
1. I use a server ,say Ubuntu server, and I install Lampp/Xampp
2.I will write a php code /shell program that will take my message as input.Using HTTP I will send it to gcm server (lets say I am not in insti ).
3.The message will go to the android devices from the GCM server.

That's right.
