create a listener that will listen to an external push server
<p>is there any build-in mechanism in Android, which could create a service or app that actully listens to some server from the out side.. something that will "Wake up" the phone and makes him receaving a message from an outside server (i am asking this coz most of the appz are working the way aroound, when the phone sending requests to an outside server to recieve data)</p>

<p>is it possible any how ?</p>

<p>thanks.</p>
