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.
