Question

Here it goes.

There are two emulator instances say A and B on same machine that is connected to internet.
Now I need to transfer a file between A and B. How do I do that ?

I writing a ftp might make sense .. but am not sure of how the ports and ips would be.
are there any thing that Android supports for easy file transfer ? (Should work between emulators)

It would be great to know all the ways to do it..
Thanks

How to communicate between two Android emulators is explained in 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 redirections 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, 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:

1. Set up the server on B, listening to 10.0.2.15:
2. On B’s
   console, set up a redirection from A:localhost: to
   B:10.0.2.15:
3. 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

Hope it helps!
