Running android emulator as server - android

I want to receive the AT command from android emulator and send the reply back from TCP client program which is written in C.
I am running Android ICS emulator on ubuntu-10.4 system as server by giving command "emulator -shell-serial tcp::4444,server" and in another terminal I am running TCP client written in C trying to connect to the same port.
I am able to see the emulator GUI coming up but I am not receiving any AT command in client.

I got the answer, in the emulator command i need to pass -radio instead -shell-serial. now I am able to receive all the AT commands in my client program

React Native 0.61.5/0.63.3 Expo 38/39 Android Cannot connect to development server

Yes I've tried the wifi (setting the ip and port) and the adb reverse tcp method and the clear text setting in AndroidManifest.xml
Its really odd because I can adb shell onto the device and curl to the development server which works and shows up in the metro terminal, however when I start the app on the device it doesn't even try to connect.
Happened on both React Native 0.61.5/0.63.3 Expo 38/39 using Android 10 and Mac Big Sur

How to get UDP data from PC to android emulator?

I'm trying to get udp packets into android emulator sent from PC.
Server is sending udp to my PC, port number 4000, and I want to see the udp packet in the android emulator.
So i tried port redirection like:
redir add udp:4000:4000
But i can’t see the packet in the android emulator. What should i change if I want to receive the Udp packet into the android emulator?
I found this open bug:
https://issuetracker.google.com/issues/80149140
and their suggested workaround works for me!
The easiest way of doing this is to run the emulator with the additional parameters:
-feature -Wifi
So launching my emulator is something like this:
cd "C:\Program Files (x86)\Android\android-sdk\emulator"
./emulator.exe -avd tablet_m-dpi_10_1in_-_api_28 -feature -Wifi
And pay close attention that its -Wifi (lowercase f and with a hyphen). You can get a list of your devices by using the command:
./emulator.exe -list-avds
And you still need to do the telnet bit after the emulator is running:
telnet localhost 5554
auth <your+code+here>
redir add udp:8000:8000

Unable to connect backend server with android emulator

Hi i am developing and android application which communicates with the backed server. I Tested my application inside my Working environment its working fine... I am able to connect to the server and i got the response...
But when i went for testing in my clients environment, i was unable to connect to the back end server.. I used their LAN to access web server...
The problem i am having is Unknown Host name..
Insted of giving the host name i gave the ip address to the host and my application got the response successfully from the server, but if i change the ip address to the DNS i was unable to connect..
I Tried several options
Tried to set the host ip address in Eclipse -> Window -> Preference -> Android -> Launch. but it didnt work.
I Tried to launch the emulator from the command line using the following command
emulator -avd MYAVD -dns-server X.X.X.X
this one also didn't work.
Since my time is limited to deploy i need help.
