Module Example not working (GumTest)

[Arjit0762]

I’m currently exploring how to add camera zoom in/out functionality to livekit

As a starting point, I tried running the GumTestApp example on my Android device, but it is throwing the following error(as attached in video)

Please help me figure out how to make it work so that I could add some functionality here

What I’m trying to do

Run GumTestApp example successfully on Android.
Add pinch-to-zoom / manual zoom controls to the camera track.
Contribute this feature back to the library.

Steps to Reproduce

Clone the repo.
Run GumTestApp on a physical Android device.
Click on Start..
