Android - How To Make 2 or More Emulator Communicate Each Other

Each emulator instance provides a control console the you can connect to, to issue commands that are specific to that instance. You can use the redir console command to set up redirections as needed for an emulator instance.

First, determine the console port number for the target emulator instance. For example, the console port number for the first emulator instance launched is 5554. Next, connect to the console of the target emulator instance, specifying its console port number, as follows:

telnet localhost 5554

Once connected, use the redir command to work with redirections. To add a redirection, use:.

redir add <protocol>:<host-port>:<guest-port>

where <protocol> is either tcp or udp, and <host-port> and <guest-port> sets the mapping between your own machine and the emulated system, respectively.

For example, the following command sets up a redirection that will handle all incoming TCP connections to your host (development) machine on 127.0.0.1:5000 and will pass them through to the emulated system's 10.0.2.15:6000.:

redir add tcp:5000:6000

Or UDP
redir add udp:5000:6000


Example:

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

Set up the server on B, listening to 10.0.2.15:<serverPort>
On B's console, set up a redirection from A:localhost:<localPort> to B:10.0.2.15:<serverPort>
On C, have the client connect to 10.0.2.2:<localPort>
