C2DM(PUSH NOTIFICATIONS ) ON ANDROID..............

this topic , may helpful to the beginners :

>There are many different ways of accomplishing the same thing (polling, constant server connections, SMS messages). But as of right now, C2DM is the best option for  keeping your Android application data up to date.


>Do not send large amounts of data in the pushes. These should be “tickles” from the server telling your Android app to go get fresh data from the server. 


>This will only work with devices running Android 2.2 and later.
>You need to have a device or emulator that is registered with a Google account. It won’t work if the emulator is “unregistered”.  Just assign a Google account to it and you’ll be fine.
>You will need some server side scripting to actually push messages to the device.
