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 "[email protected]"
All scripts support --help for detailed options and --json for machine-readable output.
Production Scripts
Build & Development
- 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
- 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
- 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
- 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
- gesture.py - Perform swipes, scrolls, and other gestures
- Swipe up/down/left/right
- Scroll lists
- Options:
--swipe,--scroll,--duration,--json
- keyboard.py - Key events and hardware buttons
- Input key events (Home, Back, Enter, Tab)
- Type text via ADB
- Options:
--key,--text,--json
- 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
- emulator_manage.py - Manage Android Virtual Devices (AVDs)
- List available AVDs
- Boot emulators
- Shutdown emulators
- Options:
--list,--boot,--shutdown,--json
- emu_health_check - Verify environment is properly configured
- Use
emu_health_check.shon macOS/Linux andemu_health_check.ps1on 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.

> Suggests using Microsoft Testing Platform (MTP) hot reload to iterate fixes on failing tests without rebuilding. Use when user says "hot reload tests", "iterate on test fix", "run tests without rebuilding", "speed up test loop", "fix test faster", or needs to set up MTP hot reload to rapidly iterate on test failures. Covers setup (NuGet package, environment variable, launchSettings.json) and the iterative workflow for fixing tests. normally with dotnet test (use run-tests), applying test filters, producing TRX reports, CI/CD pipeline configuration, or Visual Studio Test Explorer hot reload (which is a different feature).
