# limrun-android-emulator This skill drives an app on a Limrun cloud Android emulator: installs the APK, taps, types, takes screenshots and reads logs. Handy right after a build when you want to see the app run. - skill · `type=skill` · Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, OpenCode · 38700 installs · ★ 2 - Author: limrun-inc - License: MIT · policy=mirror · the beginning of the file is at the end of this page - Source: https://github.com/limrun-inc/skills/tree/HEAD/skills/limrun-android-emulator/SKILL.md - Updated: 2026-10-23 - HTML: https://affpapa.org/en/nevibecode/skills/limrun-android-emulator ## What it does The skill installs an APK on a Limrun cloud emulator and lets the agent drive the running app: tap, type, read the UI element tree, take screenshots and record video. App logs, one-shot shell commands and file transfer work without a tunnel. Full logcat and interactive tools need adb over the CLI's tunnel. Under the hood it is a set of `lim android` commands: `create`, `install-app`, `sync`, `launch-app`, `terminate-app`, `app-log`, `adb-shell`, `push-file`, `pull-file`. Building is out of scope — that is limrun-gradle's job. Install the CLI with `npm install --global lim`, then authenticate via `lim login` or the `LIM_API_KEY` variable. One thing to know: most commands default to the last created instance and resolve the current one from the git repo of your working directory. Run a command from another folder, or outside any git repo, and it may report no recent instance even though one is running. So grab the ID from `lim android list` and pass `--id` to every `lim android` call. When an agent drives this, add `--no-open` always, and `--no-connect` unless adb is needed right away. ## Install ### Claude Code (native platform) 1. **Skills CLI (Vercel)** ```bash npx skills add limrun-inc/skills --skill limrun-android-emulator -a claude-code ``` 2. **Manually: put the files in place** - File: `~/.claude/skills/limrun-android-emulator/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/limrun-android-emulator/ ### Codex 1. **Skills CLI (Vercel)** ```bash npx skills add limrun-inc/skills --skill limrun-android-emulator -a codex ``` 2. **Manually: put the files in place** - File: `.agents/skills/limrun-android-emulator/SKILL.md` — For all projects use ~/.agents/skills/ ### Cursor 1. **Skills CLI (Vercel)** ```bash npx skills add limrun-inc/skills --skill limrun-android-emulator -a cursor ``` 2. **Manually: put the files in place** - File: `.cursor/skills/limrun-android-emulator/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/ ### GitHub Copilot 1. **GitHub CLI** ```bash gh skill install limrun-inc/skills limrun-android-emulator ``` 2. **Manually: put the files in place** - File: `.github/skills/limrun-android-emulator/SKILL.md` ### Gemini CLI 1. **Skills CLI (Vercel)** ```bash npx skills add limrun-inc/skills --skill limrun-android-emulator -a gemini-cli ``` 2. **Platform CLI** ```bash gemini skills install https://github.com/limrun-inc/skills --path skills/limrun-android-emulator ``` ### Windsurf (Devin Desktop) **Manually: put the files in place** - File: `.devin/skills/limrun-android-emulator/SKILL.md` — The legacy .windsurf/skills/ path still works ### OpenCode **Skills CLI (Vercel)** ```bash npx skills add limrun-inc/skills --skill limrun-android-emulator -a opencode ``` ### Claude.ai **Claude.ai** - Zip the folder and upload it in Settings → Capabilities → Skills Where a file is given instead of a command, copy the files from the source to that path: https://github.com/limrun-inc/skills/tree/HEAD/skills/limrun-android-emulator/SKILL.md ## When to use it - install a built APK on a cloud emulator and launch the app - capture a screenshot or record a video of the running app - read app logs and the crash stack trace after a failure - tap an element and inspect the UI element tree - move a file to the emulator and back without a local SDK ## Example prompts - build the APK and show me a screenshot of the app on the emulator - launch com.example.app and check logcat for errors - record a video of the app going through the login screen ## Source text · SKILL.md · MIT Below is the content of a third-party file.

BEGIN THIRD-PARTY FILE 60cb6961bd106259 ````text --- name: limrun-android-emulator description: "Drive an app running on a Limrun cloud Android emulator: install an APK, launch and terminate apps with crash reports, tap, type, read the UI element tree, screenshot, record video, inject microphone audio, shape network bandwidth, read app logs, run shell commands, transfer files, tunnel the app's network destinations through your machine with HTTP inspection and HAR capture, reach a private network through a private tunnel, send all traffic through the user's proxy, trust a custom CA certificate, and use adb over the CLI's tunnel for full logcat and interactive tools. Use after a build (from limrun-gradle or any builder) when the user wants to see, test, or interact with their app on an emulator, or says 'show me a screenshot', 'tap', 'run it on the emulator', 'check logcat', 'record a video', 'inspect network traffic', 'route all traffic through my proxy', or 'reach my local server from the emulator'. To build the APK or AAB first, use limrun-gradle." user-invocable: true effort: high --- # Limrun Android Emulator Interact with an app running on a Limrun cloud Android emulator, from any environment (Linux, Windows, macOS, VM, container). This skill is build-agnostic: it assumes the APK was already built, usually by **limrun-gradle**. Keep build concerns in that skill; this one is about driving the running emulator. Never use a local emulator, a local Android SDK, or Android Studio. ## Auth and CLI Install if needed: `npm install --global lim`. Auth is `lim login` or `LIM_API_KEY` (it may already be set in the user's environment even when `.env` and the shell do not show it; check before asking for it). The CLI is the source of truth: the commands in this skill are verified, but if a flag errors or you need one not shown here, check `lim android --help` instead of guessing. ## Installing an app You can build with Limrun's remote Gradle service and have the APK installed on a fresh emulator automatically, or install a pre-built local APK or a URL. One default to know first: `lim android create` opens an ADB tunnel (`--connect`) and a browser tab with the live stream (`--open`) unless told otherwise. As an agent, pass `--no-open` always, and `--no-connect` unless you need adb right away. ### Build and install Upload the APK built by **limrun-gradle** as a named asset, then create an emulator with it pre-installed: ```bash lim gradle build . --upload myapp.apk ```` END THIRD-PARTY FILE 60cb6961bd106259 The third-party file has ended.
