This looks like an issue loading the JS bundle from the Metro server. I’d check two things:
Is Metro running? Is it on port 8081? This is normally started by npx torchlive-cli run-android. You can also run yarn start in the project directory to run the Metro server without deploying the app.
If it’s still an issue on the physical device, you may need to ensure requests are forwarded correctly by running adb reverse tcp:8081 tcp:8081 like in this FAQ item: FAQ | Easy to use set of tools to create on-device ML demos on Android and iOS. Unlock the vast potential of AI innovations. 1
