Native crash at startup on Pixel 9a / Pixel 10a (Tensor G4/G5): emulator hardware checks

[lele872]

Environment

• Library: rasp-android 0.7.1 (latest)
• Devices affected: Pixel 9a (Tensor G4) and Pixel 10a (Tensor G5)
• Works fine on: Pixel 8 (Tensor G3, hw "zuma"), Pixel 7, Pixel 6
• OS: GrapheneOS (also reported by users on stock-like hardened setups), build 2026081300
• Symptom: app crashes at install or immediately at first launch, before any UI

Description

We use SecureApp.init() in onCreate and a SecureAppChecker with all three check groups enabled (emulator/debugger/root). On the newer Tensor SoCs the app dies at startup. On Tensor G3 and older everything works. This looks very similar to issue #5 (crashes on certain hardware, emulator_checks_DeviceChecks_*), where the cause was hardware not recognized by the emulator checks.

Workaround we applied

We now skip only checkEmulator on SoCs we haven't tested (allowlist on Build.SOC_MODEL/HARDWARE), keeping root/debugger checks active — this stops the crash on 9a/10a. Sharing in case it helps other users.

Ask

Could the emulator hardware checks be made resilient (fail-safe returning "unknown" instead of crashing) when the SoC is not in the known list? Happy to provide a crash logcat from an affected device if useful.

Thanks for the library!
