Summary

• XHarness fails to find attached device supporting armeabi-v7a (32-bit ARM) architecture on Android arm32 jobs.
• Device enumeration succeeds but available devices (e.g., Pixel 9a) only support arm64 or x86/x86_64, not arm32.
• Exit code 81 (DEVICE_NOT_FOUND) indicates architectural mismatch between test configuration (arm32/armeabi-v7a) and available device hardware.
• Occurs on Android arm32 Mono test runs with physical device infrastructure.

Base on the Pixel release notes, starting with Pixel 7, the flagship phones are 64 bit only https://android-developers.googleblog.com/2022/10/64-bit-only-devices.html. As the old Pixel 4a devices are getting replaced in the lab (for Pixel 9a), we're going to lose testing coverage over android-arm (32 bit). cc: @vitek-karas @steveisok

We could see if there are any old Pixels left in the lab and create a dedicated queue for smoke tests on arm32 bit Android until it is EOL or we could see if there is arm64 ubuntu/windows queue and run 32 bit emulators instead.

We could see if there are any old Pixels left in the lab and create a dedicated queue for smoke tests on arm32 bit Android until it is EOL or we could see if there is arm64 ubuntu/windows queue and run 32 bit emulators instead.

My vote is to explore the emulator path. I think it'll be increasingly harder to keep devices (and enough of them) around.
