FINAL RESULT: Native Android installation/launch was not verified.
Host Linux x64 has no /dev/kvm hardware acceleration. After resolving stale AVD state and freeing space for the emulator userdata partition, a fresh Android 15/API 35 x86_64 emulator connected through ADB but did not complete boot within 600 seconds. The attempt was terminated; no APK installation or application launch result is claimed. Physical-phone testing is also unavailable. APK integrity, JVM storage tests and controlled phone-interface tests passed separately.
