android-emulator-skill

name: android-emulator-skillversion: 1.0.0description: Production-ready scripts for Android app testing, building, and automation. Provides semantic UI navigation, build automation, log monitoring, and emulator lifecycle management. Optimized for AI agents with minimal token output.

Android Emulator Skill

Build, test, and automate Android applications using accessibility-driven navigation and structured data instead of pixel coordinates.

Quick Start

# 1. Check environment (use .sh on macOS/Linux, .ps1 on Windows)
bash scripts/emu_health_check.sh
# or on Windows: .\scripts\emu_health_check.ps1

# 2. Launch app
python scripts/app_launcher.py --launch com.example.app

# 3. Map screen to see elements
python scripts/screen_mapper.py

# 4. Tap button
python scripts/navigator.py --find-text "Login" --tap

# 5. Enter text
python scripts/navigator.py --find-type EditText --enter-text "user@example.com"

All scripts support --help for detailed options and --json for machine-readable output.

Production Scripts

Build & Development

1. build_and_test.py - Build Android projects, run tests, parse results

   • Wrapper around Gradle
   • Support for assemble, install, and connectedCheck
   • Parse build errors and test results
   • Options: --task, --clean, --json

2. log_monitor.py - Real-time log monitoring with intelligent filtering

   • Wrapper around adb logcat
   • Filter by tag, priority, or PID
   • Deduplicate repeated messages
   • Options: --package, --tag, --priority, --duration, --json

Navigation & Interaction

3. screen_mapper.py - Analyze current screen and list interactive elements

   • Dump UI hierarchy using uiautomator
   • Parse XML to identify buttons, text fields, etc.
   • Options: --verbose, --json

4. navigator.py - Find and interact with elements semantically

   • Find by text (fuzzy matching), resource-id, or class name
   • Interactive tapping and text entry
   • Options: --find-text, --find-id, --tap, --enter-text, --json

5. gesture.py - Perform swipes, scrolls, and other gestures

   • Swipe up/down/left/right
   • Scroll lists
   • Options: --swipe, --scroll, --duration, --json

6. keyboard.py - Key events and hardware buttons

   • Input key events (Home, Back, Enter, Tab)
   • Type text via ADB
   • Options: --key, --text, --json

7. app_launcher.py - App lifecycle management

   • Launch apps (adb shell am start)
   • Terminate apps (adb shell am force-stop)
   • Install/Uninstall APKs
   • List installed packages
   • Options: --launch, --terminate, --install, --uninstall, --list, --json

Emulator Lifecycle Management

8. emulator_manage.py - Manage Android Virtual Devices (AVDs)

   • List available AVDs
   • Boot emulators
   • Shutdown emulators
   • Options: --list, --boot, --shutdown, --json

9. emu_health_check - Verify environment is properly configured

   • Use emu_health_check.sh on macOS/Linux and emu_health_check.ps1 on Windows
   • Check ADB, Emulator, Java, Gradle, ANDROID_HOME
   • List connected devices

Common Patterns

Auto-Device Detection: Scripts target the single connected device/emulator if only one is present, or require -s <serial> if multiple are connected.

Output Formats: Default is concise human-readable output. Use --json for machine-readable output.

Requirements

• Android SDK Platform-Tools (adb, fastboot)
• Android Emulator
• Java / OpenJDK
• Python 3

Key Design Principles

Semantic Navigation: Find elements by text, resource-id, or content-description.

Token Efficiency: Concise default output with optional verbose and JSON modes.

Zero Configuration: Works with standard Android SDK installation.
