Answer 1

You need something more interactive, so that you don't need to poll for new messages. Try xmpp. WhatsApp uses the same protocol (well a little other encoded) and even Google Talk. Alternative you could try websockets.

Answer 2

Yes. You can use http protocol for communication.
use JSON or xml or etc.
But, before set or make webserver.
otherwise you can use GCC(Google Cloud Message) for sending message between android device.
