adb forward remote port to local machine

Question

This is a query regarding the usage of adb on android.

Is there a way to forward the remote port i.e. port on the android device/emulator to the local machine to which the device is connected?

$ adb forward tcp:port1 tcp:port2 # forwards the local port port1 on the machine to port2 on the device.

Thanks in advance!

Answer 1

Do you truly need to forward the port or are you just looking for a way to communicate using sockets from a program running on the android shell to your host machine? I was able to accomplish the latter by sending my message to the port of interest on "10.0.2.2", which is the loopback adapter of the host machine. See docs here.

This is the updated link

Recently google updated ADB service. And added reverse command that should do the job.

From reverse documentation:

This implements the adb reverse feature, i.e. the ability to reverse socket connections from a device to the host. <forward-command> is one of the forwarding commands that are described above, as in:

1. list-forward
2. forward:<local>;<remote>
3. forward:norebind:<local>;<remote>
4. killforward-all
5. killforward:<local>

Note that in this case, <local> corresponds to the socket on the device and <remote> corresponds to the socket on the host.

The output of reverse:list-forward is the same as host:list-forward except that <serial> will be just host.
