How to push my data to my android phone

Hi, there I am really a newer for the arduino . Recently, I am going on a small project with my arduino,wifi shield,android phone and temperature sensor.I intended to get warnings when the temperature is too high. Now,I have connected my arduino board which have been made to a server and my wifi shield with temperature sensor.I have created a threshold so that the server(arduino)will push warnings to my android phone. My question is how to push data to my android phone automatically. Thank you for your sincere help.

My question is how to push data to my android phone automatically.

Do you mean that you would like the Arduino to send data to the phone even though the phone is not asking for it?

In my (admittedly limited) experience of web programming the client / browser has to initiate the communication with the server. That means that the Android browser (or whatever program is taking its place) would make a request to the Arduino which would then reply with the appropriate data.
