There's no easy way, what you could do is use a library like asmack to create server-client 'chat like' communication but the problem its time consuming to build it and maintain it. Other solution for third party services is Xtify they provide a free Push notification (only advance feature that you pay for) for android 1.6 and above also complete c2dm solution.
