title: 'Android Control'
description: 'Learn how to control Android devices in DroidRun using the comprehensive tools API.
Tools provide the bridge between your AI agents and Android devices, enabling UI interaction, app management, and state analysis. Use tools directly or through DroidAgent for automated Android testing and control.'
---
```python
from droidrun import DroidAgent, AdbTools
# Load tools for a device
tools = AdbTools(serial="device_serial")
# Create agent with tools
agent = DroidAgent(
goal="Your task",
llm=llm,
tools=tools
)
```
## UI Interaction Tools
**`tap_by_index(index: int) -> str`**
Tap on a UI element by its index from cached elements. Must call `get_state()` first.
**`swipe(start_x: int, start_y: int, end_x: int, end_y: int, duration_ms: int = 300) -> bool`**
Perform swipe gesture. For long press, use same start/end coordinates with longer duration.
**`input_text(text: str) -> str`**
Input text into focused element. Supports special characters and non-ASCII text.
**`press_key(keycode: int) -> str`**
Press Android keys using keycodes. Common: HOME (3), BACK (4), ENTER (66), DELETE (67).
**`back() -> str`**
Convenience method to press the Android back button.
```python
# UI interaction examples
await tools.get_state() # Cache elements first
await tools.tap_by_index(2) # Tap element
await tools.swipe(500, 200, 500, 800, 400) # Swipe down
await tools.input_text("Hello, World!")
await tools.press_key(66) # Enter key
await tools.back()
```
## App Management Tools
**`start_app(package: str, activity: str = "") -> str`**
Start application by package name and optional activity.
**`list_packages(include_system_apps: bool = False) -> List[str]`**
List installed packages. Optionally include system apps.
**`install_app(apk_path: str, reinstall: bool = False, grant_permissions: bool = True) -> str`**
Install APK file with optional reinstall and permission granting.
```python
# App management examples
await tools.start_app("com.android.settings")
packages = await tools.list_packages()
all_packages = await tools.list_packages(include_system_apps=True)
await tools.install_app("/path/to/app.apk", reinstall=True)
```
## State Analysis Tools
**`get_state(serial: Optional[str] = None) -> Dict[str, Any]`**
Get comprehensive device state including accessibility tree and phone state. Caches UI elements.
**`take_screenshot() -> Tuple[str, bytes]`**
Capture device screen and return format and image data. Stores screenshots for GIF creation.
```python
# State analysis examples
state = await tools.get_state()
a11y_tree = state["a11y_tree"]
phone_state = state["phone_state"]
format, image_data = await tools.take_screenshot()
```
