Trying to use Firebase MLKit barcode scanner, "Waiting for the barcode detection module to be downloaded, please wait" appears on emulator screen

Question

I am trying to make a barcode scanner using Java and MLKit in Android Studio, but keep getting this message when I run the app in the emulator. I have an inte.net connection and I have tried clearing the emulated device's data. Running the emulation on a Pixel 2 XL API 29.

Can provide code if needed, but there are no errors in my code currently. I followed a tutorial line for line but for some reason cannot get it to work.

Messages in Run:

I/DynamiteModule: Considering local module com.google.android.gms.vision.dynamite:0 and remote module com.google.android.gms.vision.dynamite:2702

thank you in advance.

Hmm... MLKit barcode scanner needs for sure real device with a camera. I'm quite sure it is useless to try to test app with an emulator.
