Android has only recently added support for running the Android emulator on M1 Mac hardware; Briefcase has not yet been updated to provide this support. I suspect this should be a matter of updating the SDK Manager components to reflect the M1 hardware target instead of x86.

@freakboy3742 Hi, I would like to start work on this issue, it is possible to test somehow without M1 hardware?

[freakboy3742]

@zili Unfortunately not - pretty much by definition, the M1 emulator will only run on M1 hardware.

ok then someone with M1 hardware can take this issue
