// Orchestrates Android development tasks including project creation, deployment, SDK management, and environment diagnostics using the `android` command-line tool.
Use when the user asks to address PR review comments — from human reviewers or automated bots (Gemini, Coderabbit, Copilot, SonarCloud, etc.) — to triage and respond to feedback on a pull request
Use to find stuck coroutines, leaked jobs, and suspended awaits with no resumer — the concurrency bugs that don't crash but cause hangs, missing UI updates, or memory creep. Ephemerally add `kotlinx-coroutines-debug`, install `DebugProbes` in `Application.onCreate`, run the suspect flow, dump active coroutines with stack traces, fix, then remove the dependency and the install/dump calls. Reach for this when `Log.d` shows a `launch` ran but `collect` never received, or a screen leaves and something keeps running.
Use to flush out intermittent crashes and ANRs ("it crashes sometimes," "fails on slow devices," "happens after rotation a few times") by scripting the trigger sequence with `adb shell input` and running it in a shell loop against a cleared logcat, stopping on first match for `FATAL EXCEPTION` or `ANR in`. Inject deterministic stress (rotation, slow network, low memory) to surface latent races. The empirical answer to "is this still a bug, and under what conditions?"
Use to extract concrete numbers and slice-level evidence from a `.perfetto-trace` captured by `android-perfetto-capture`. Run SQL queries against the trace via the `trace_processor` binary, then hand the (small) result file to a Sonnet sub-agent for verdict — never read raw trace data inline. This is where "the app feels slow" becomes "frame 42 missed budget by 8.3 ms because `MainActivity.onResume` ran 18 ms on `main` while the IO dispatcher was idle." The analysis half of the perfetto loop.
Use to capture Perfetto system traces from a connected Android device — the input for any timing, threading, jank, or "is this on the main thread?" investigation. Writes a self-contained `.perfetto-trace` file to `/tmp` that downstream skills (`android-perfetto-analyze`, `android-trace-sections`) read with the `trace_processor` SQL backend. Pick the strategy that matches the question (one-shot, repeated, on-the-fly), drive the suspect flow during the recording window, and verify the trace contains the expected slices before declaring capture done.
Use when you need empirical proof a code path actually executed — branch entries, callback fires, coroutine continuations, suspect early returns. Insert temporary `Log.d` calls with a unique sentinel tag, redeploy, drive the app, read filtered logcat, then remove every probe before declaring done. The default investigation skill when the question is "did this run, in what order, with what values?"

This skill provides instructions for using the android CLI tool. The tool includes various commands for creating projects, running applications, interacting with devices, and managing the CLI environment.
This skill assumes the android CLI is already installed and on PATH. If android --version fails, install the CLI first (consult its official documentation for the install method appropriate to your platform), then re-run the failing command.
To manage the installation of Android SDKs and tools, use the sdk command. For example:
android sdk install <package>[@<version>]...: Install specific packages. Multiple packages can be specified, separated by spaces. <version> defaults to latest. For example: android sdk install platforms/android-30@2 platforms/android-34android sdk update [<pkg-name>]: Update a specific package or all packages to the latest version.android sdk remove <pkg-name>: Remove a package from the local SDK.android sdk list --all: List installed and available SDK packages.Create projects from templates using the create command.
For example: android create empty-activity --name="My App" --output=./my-app
For inspecting on-screen UI and driving taps, swipes, and text input from element coordinates, use the verify-android-layout skill — it covers the JSON shape returned by android layout, --diff for iteration loops, and the full adb shell input workflow. Use verify-android-screen when a screenshot is required (WebView, animation, visual fidelity).

The docs command searches authoritative, high-quality Android developer documentation in the Android Knowledge Base.
By providing a few keywords, this tool will return high quality articles that contain examples or guidance on how to use Android APIs or libraries.
Use this tool to obtain additional information on how to achieve Android-specific tasks or to know more about Android APIs, surfaces, libraries, or devices.
Always use this tool to get the most up-to-date information about Android concepts. Typical good use cases are:
Use the run command to run Android apps.
Manage Android Virtual Devices (AVDs) using the android emulator command
Two skills cover Android UI verification — pick based on what you need to check:
verify-android-layout — default for almost everything. Uses android layout to get a structured JSON tree of the on-screen UI (text, resource ids, bounds, state, interactions). Cheaper and more precise than a screenshot. Use --diff in iteration loops to get only what changed.verify-android-screen — fallback for WebView content, animations, visual fidelity (colors, fonts, image content), or finding elements by appearance via android screen capture --annotate.Reach for verify-android-layout first; only escalate to verify-android-screen when JSON can't answer the question.
When a change isn't behaving and final UI verification can't tell you why, reach for an investigation skill. The shape is always probe → run → observe → remove — every probe gets cleaned up before the task is done.
android-probe-logging — default. Insert temporary Log.d with a unique sentinel tag to confirm a code path runs, see the actual values, and check execution order.android-reproduce-as-test — default for any non-trivial bug. Write a failing test that captures the bug, fix until green, leave the test as a regression guard.android-strictmode-probe — silent main-thread I/O, leaked closeables, activity leaks. Catches things that don't crash but cause jank or memory creep.android-snapshot-diff — capture state at A, act, capture at B, diff. The empirical answer to "did anything actually change?"android-regression-diff-scan — instead of git bisect, hand the full git diff <good> <bad> to a sub-agent. Faster than waiting on slow mobile builds.android-crash-repro-loop — script the trigger sequence and run it 50× to flush out intermittent crashes; inject stress (rotation, slow network, low memory) for races.android-trace-sections — wrap suspect code in Trace.beginSection / endSection (or the trace { } lambda) so the slices appear in a Perfetto trace. The source-side half of the perf loop.android-perfetto-capture — capture a .perfetto-trace from the device (one-shot host script, on-device long-running, or in-app SDK). The capture half of the perf loop.android-perfetto-analyze — run trace_processor SQL queries against a .perfetto-trace. Recipes for slice-by-thread, frame budget, main-thread breakdown, GC, binder, recompositions. The analysis half of the perf loop.android-runtime-flag-probe — flip framework debug flags via adb shell setprop (debug.layout, log.tag.X VERBOSE, hwui.profile) without code changes.android-coroutine-trace — DebugProbes snapshot of every active coroutine. Use when Log.d shows launch fired but collect never received.Manage antigravity agent skills for Android using the android skills command.
