description: >
  Manipulates Android devices via ADB with emphasis on Wear OS. Provides scripts
  for screenshots, screen recording, tile management, WearableService
  inspection, package operations, and device configuration. Use when working
  with adb, Android devices, Wear OS watches, tiles, wearable data layer,
  dumpsys, or device debugging. Triggers: adb, android device, wear os,
  wearable, tile, screenshot, screen recording, dumpsys, logcat.
compatibility: >
  Requires adb. Some scripts require magick (ImageMagick), aapt, or scrcpy.
  Designed for filesystem-based agents with bash access.

Android ADB

Important: Use Scripts First

ALWAYS prefer the scripts in scripts/ over raw adb commands. Scripts are located in the scripts/ subdirectory of this skill's folder. They provide features that raw commands do not, such as:

  • •Automatic circular masking for Wear OS screenshots
  • •Device wake-up before capture
  • •Clipboard integration on macOS
  • •Sensible default filenames and error handling

When to read the script source: If a script doesn't do exactly what you need, or fails due to missing dependencies, read the script source. The scripts encode solutions to edge cases and platform quirks that may not be obvious—use them as reference when building similar functionality.

Quick Start

Target specific devices using the ANDROID_SERIAL environment variable if multiple devices are connected.

Highest-Value Commands

  • •

    Screenshot (auto-masks circular Wear OS displays): scripts/adb-screenshot

  • •

    Wear OS Tile Debugging Workflow: scripts/adb-tile-add com.example/.MyTileService -> output gives INDEX scripts/adb-tile-show INDEX

  • •

    Inspect Wear OS Data Layer: adb exec-out dumpsys activity service WearableService

  • •

    Package Information: scripts/packagename tiles PACKAGE_NAME scripts/packagename services PACKAGE_NAME

  • •

    Device Info: scripts/adb-device-properties

  • •

    Discover Activities: scripts/adb-activities (find launcher, TV, settings activities)

Script Index

See references/command-index.md for detailed usage.

Device Basics

  • •scripts/adb-devices: List connected devices.
  • •scripts/adb-device-properties: Show key device properties (model, manufacturer, etc.).
  • •scripts/adb-api-level: Get the device API level (SDK version).
  • •scripts/adb-keyevent-wakeup / sleep: Wake up or put device to sleep.
  • •scripts/adb-log: Write a message to the system log.
  • •scripts/adb-logcat-tag: Stream logcat output filtered by a specific tag.
  • •scripts/adb-version-sft: Extract the Health Tracking GmsModule version.

Media Capture

  • •scripts/adb-screenshot: Take a screenshot. Always use this instead of raw adb shell screencap. Features: auto-detects square Wear OS displays and applies circular mask, wakes device before capture, copies to macOS clipboard, generates timestamped filenames by default.
  • •scripts/adb-screenrecord: Record the screen to a file.
  • •scripts/adb-screenmirror: Mirror the device screen using scrcpy.
  • •scripts/adb-screenrecord-raw: Record the screen using raw frames and ffmpeg.

Tile Management (Wear OS)

  • •scripts/adb-tile-add: Add a tile component for debugging.
  • •scripts/adb-tile-show: Show an added tile.
  • •scripts/adb-tile-remove: Remove a tile.
  • •scripts/adb-tiles: List currently added tiles.
  • •scripts/adb-watchface-add: Set the current watch face.

Activity Discovery

  • •scripts/adb-activities: List activities tagged by category (Launcher, Home, TV/Leanback, Settings). Use --launcher-only, --tv-only, --settings-only to filter. Add --all to include system apps.
  • •scripts/adb-uihierarchy: Dump the UI hierarchy to an XML file.
  • •scripts/adb-currentfocus: Display the package name that currently has focus.
  • •scripts/adb-intent-view: Start an activity with a VIEW intent.

Package Operations

  • •scripts/packagename: Comprehensive package tool (uninstall, launch, stop, clear-cache).
  • •scripts/adb-logcat-package: Show logcat filtered for a specific package.
  • •scripts/apk-tiles: List tiles declared in an APK file.
  • •scripts/adb-packages: List installed packages.
  • •scripts/apk-cat-manifest: Display the AndroidManifest.xml from an APK.

System & Dumpsys

  • •scripts/adb-battery-stats: Display battery-related information and settings.
  • •scripts/adb-jobscheduler: Display dumpsys information for the Android JobScheduler.

Display & Demo Mode

  • •scripts/adb-demo-on / off: Toggle Android demo mode (clean status bar).
  • •scripts/adb-fontscale-default / large: Change font size.
  • •scripts/adb-theme: Get or set system theme customization (e.g., set to 'lemongrass'). Requires Wear OS 6+ (API 36+).
  • •scripts/adb-settings-theme: Open system theme settings (requires root/debuggable build).
  • •scripts/adb-touches-on / off: Show/hide taps on screen.

Safety Notes

  • •Debug Broadcasts: Tile management relies on Wear OS debug broadcasts (com.google.android.wearable.app.DEBUG_SURFACE) which may not work on production builds without developer options or specific system images.
  • •USB Debugging: Requires adb authorization.
  • •Destructive Actions: Scripts like adb-tile-remove or packagename uninstall modify device state.
