Push on web and mobile

Hi, someone can explain to me how I could implement a service to push messages on web and mobile (Android) using Java?

. . . and welcome to the Ranch

We didn't notice you until you posted

I think this question would sit better on a different forum, so I shall move it.

Thank you, sorry for my mistake...

Please help me, how can I push messages on web and mobile?

There are a number of ways you can push messages to your device:

-> Polling - The mobile application would periodically poll one of your services and check for messages. However, as numerous people have pointed out, notifications are no good if they’re delayed due to a low polling period but the more frequently you poll, the more the battery is going to die.

-> SMS - Android can intercept SMS messages but you are limited by the size of the SMS payload.

-> Open a persistent connection - This fixes the polling issue listed above but would kill the battery.

Now, the leading push notification framework for Android seems to be Android Cloud to Device Messaging Framework (http://code.google.com/android/c2dm/#push) but it is in beta and you have to apply.

Another option is MQTT (IBM), a real good overview can be found here (http://tokudu.com/2010/how-to-implement-push-notifications-for-android).
