[New Feature] Add wired (USB) support for Android devices
Describe the new feature you'd like I propose adding a method to share audio from an Android phone to the computer, effectively using the phone as a microphone, through a USB connection with the Android Debug Bridge (ADB).
Describe the reason why you want to add the feature This feature would provide a superior user experience compared to a wireless connection, offering lower latency and higher audio quality. Additionally, a wired USB connection allows the phone to be charged by the computer simultaneously.
Describe how to implement the feature if you can As I am not a developer, I cannot provide a specific implementation plan. However, a similar feature exists in a software called "WO Mic," which uses the Android Debug Bridge to turn a phone into a microphone. This might serve as a helpful reference.
You can forward a port over ADB to achieve this.
adb reverse tcp:65530 tcp:65530
Then, set the IP on the phone to 127.0.0.1.

@1upbyte Thank you for your suggestion.
Unfortunately, this solution didn't work for me. The client application shows the following error:
Not enough data available, required 4 bytes but only 0 available.
After some research, it seems the issue is that adb reverse only forwards TCP connections, not UDP. However, it appears this application requires both TCP and UDP protocols to function correctly.
Weird. I have it working. I got the same error as you when I didn't start the server on the PC. Also try with --bind=127.0.0.1 on the server.
@1upbyte Thanks a lot, your suggestion worked to get the client connected!
Now, however, there's no audio output on the phone, even though the connection is active.
Here are the two corresponding log files:
