Hello,
If you want to test on your own Android physical device, you need to enable developer options and turn on USB debugging. This is related to the specific method of opening USB debugging and the specific mobile phone device vendor, please search for your mobile phone model how to turn on USB debugging.
Then, you could refer to the following documentations to debug your Xamarin project on your devices.
Best Regards,
Alec Liu.
