Answer 1

See the ” Interconnecting Emulator Instances ” part here
http://developer.android.com/guide/developing/devices/emulator.html

Interconnecting Emulator Instances

To allow one emulator instance to communicate with another, you must set up the necessary network redirection as illustrated below.
Assume that your environment is

A is you development machine

B is your first emulator instance, running on A

C is your second emulator instance, also running on A

and you want to run a server on B, to which C will connect, here is how you could set it up:

1. Set up the server on B, listening to 10.0.2.15:
   1. On B’s console, set up a redirection from A:localhost: to B:10.0.2.15:
2. On C, have the client connect to 10.0.2.2:

For example, if you wanted to run an HTTP server, you can select as 80 and as 8080:

B listens on 10.0.2.15:80

On B’s console, issue redir add tcp:8080:80

C connects to 10.0.2.2:8080
