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
bash scripts/emu_health_check.sh

# 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

1. 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

2. 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

Emulator Lifecycle Management

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

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

2. emu_health_check.sh - Verify environment is properly configured

   • 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.
