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

This is the error message i keep getting when i try to run app on emulator
RuntimeError: abort(Error: could not connect to TCP port 5554: cannot connect to 127.0.0.1:5554: No connection could be made because the target machine actively refused it. (10061)). Build with -s ASSERTIONS=1 for more info.
What are the best ways to tackle this?
I have tried running my android emulator to test what am building but instead it is showing me those error message
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
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
Here is my detail about my problem:
what I want to achieve:
create a pipeline on azure DevOps, containing tasks
create android emulator with internet condition full
run some tests
connect telnet
connect telnet to android console port- send command to android device to change nework condition to low bandwidth as mentioned here (https://developer.android.com/studio/run/emulator-console)
Note: I have hosted MacOS, also telnet+expect and spawn is installed over it
What is the problem:
My android device is running over 5037 port
telnet task output showing me "telnet connected to local host" command I am using to connect to android console port is : telnet localhost 5037 (in a command line task)
escape character is "^]"
**
it is not showing me any authentication required message or OK so I can go ahead with it, also I am trying to send command like expect"^]" returning me nothing

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.
