Verify and debug native, React Native, Expo, or Flutter apps on an Android Emulator with agent-device. Use when an agent needs to launch an app, inspect its live UI, tap, type, scroll, validate a code change, collect failure evidence, or reproduce a workflow on an Android virtual device.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Android Emulator Require the `agent-device` CLI to be installed separately before driving an emulator: ```bash npm install -g agent-device@latest ``` Treat installation and upgrades as user-owned setup steps. Do not run that command autonomously or substitute a mutable `npx -y agent-device@latest` invocation. For a normal app-driving task, start immediately. Do not probe first with `--help`, `--version`, `devices`, `appstate`, `snapshot`, or `screenshot`. Target Android explicitly when opening an app or package id: ```bash agent-device open <app-or-package-id> --platform android --foreground ``` Follow the initial interactive snapshot and corrective error hints. If the shell reports that `agent-device` is unavailable, stop and ask the user to install it or expose their existing installation on `PATH`. Only when the task is specialized or a command shape is unclear, read the relevant version-matched help topic: ```bash agent-device help validate # engineering validation and build freshness agent-device help debugging # screenshots, logs, traces, video, and failures agent-device help react-native # React Native and Expo runtime guidance …

How to install
mdr add callstack/agent-device/android-emulator@sha256:fb3aae802cc816c1The line at the top of this page pins the label git:20261016.610de02, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
