I have a problem running an Android app in the emulator. The emulator will display the app's window, but it will not show any controls. It runs fine on linux.

I'll append the source code and the briefcase messages in a moment, but here are some debug messages from briefcase that stand out to me, in the order in which they appear:

W/dbunny.togates: Unexpected CPU variant for X86 using defaults: x86_64

Here's the full output from briefcase in response to "briefcase run android.". I'm running it on Ubuntu 24.04:

Hello @rjrx23dev. Does it work on Android if you run briefcase run android -ur? The -u flag will ensure changes to your source code are incorporated in to the Android build and the -r flag ensures that the project's dependencies are up-to-date.
