How to read this page

A scenario is one test case: prepare the environment, run the steps, then compare the expected result (written before the run) with the observed result (copied from the run, with screenshots).

S02 · S
Run on a simulator or emulator — a virtual device on a computer.
Validated
Run, and the result matched what was expected.

Why it matters

Emulator detection needs a strong indicator (goldfish/ranchu hardware, qemu files or a generic fingerprint), so real phones are not flagged.

Environment

App
Example app (Expo SDK 57, React Native 0.86)
Device
Pixel 9 Pro emulator (sdk_gphone16k_arm64), API 37
Build
Debug, installed with adb
Library
0.2.0

Setup

Prepare the environment.Then run the steps.

  1. 01Install the example app on the emulator.
  2. 02Leave all options at their defaults.

Steps

What to run.What to read.

  1. 01Open the app.
  2. 02Read the status badge and the signal list.

Re-confirmed on library 0.3.0 (2026-10-06), which adds bootloader_unlocked: the Pixel_9_Pro emulator (Google Play image, Android 17, sdk_gphone16k_arm64) running the example app's release build from the v0.3.0 tag reported clean with only emulator, on four cold starts. This image reports no verified boot state at all (ro.boot.verifiedbootstate, flash.locked and vbmeta.device_state are empty), so bootloader_unlocked cannot fire on it. Run times varied from 20 ms to 3 s because the emulator was running on software graphics (SwiftShader).
