Android Emulator Web Browser Needs Camera Permissions on macOS Catalina

I am in charge of testing a mobile-compliant website that also needs access to the device camera and microphone. I needed to expand the ability to test different Android devices, so I downloaded the Android SDK and created virtual devices. However, if I set the camera of any virtual device to "Webcam0" (to use my computer's webcam) and go to the url via the built in web browser, the entire emulator crashes immediately. macOS then generates the following report:

Process:               qemu-system-x86_64 [1487]

Termination Reason:    Namespace TCC, Code 0x0

The "Namespace TCC" points to a privacy issue. The new Catalina makes it v hard to access the camera (https://carlashley.com/2018/09/28/tcc-round-up/). I have googled how to work around the issue for Android development and the responses are something like the following:

If your app uses device cameras, include the NSCameraUsageDescription key in your app’s Info.plist file.

If your app uses device microphones, include the NSMicrophoneUsageDescription key in your app’s Info.plist file.

That's great for someone who is actually building a native Android App, but I just want to launch the Android emulator and use its default web browser to test a website.

  1. Is it overkill to use Android Emulator for this purpose? In other words, can I simply go to Dev Tools in Chrome desktop and resize the browser to the target dimensions of whatever Android device I want to test?

And

  1. If it were not overkill / I had to do it via the Emulator, how would I do it? My hunch is to build a custom Chromium apk with the NSCameraUsageDescription settings in Info.plist and put it into the emulator via instructions here: https://developers.google.com/web/t...er-browsers#chromium_content_shell_on_android but that would require pulling down Chromium and making a custom build.

Has anyone else gotten their android emulator web browser to access the webcam of on macOS Catalina? What were the steps?

I was running into a similar issue trying to access the Camera from the Android Emulator. What I ended up having to do was following the steps listed here to run the emulator manually through the command line:

https://developer.android.com/studio/run/emulator-commandline

Only addition is you'll have to run the command with the sudo permissions.
