Android Device Control

CLI for Android device control via ADB. Requires device connected with USB debugging enabled.

Prerequisites

Before using this skill:

1. Android device with USB debugging enabled
2. ADB installed (adb version should work)
3. Device connected via USB or emulator running

Agent Installation (Autonomous Setup)

When this skill is not installed, agents should:

1. Run installer (recommended):

   curl -fsSL https://raw.githubusercontent.com/iurysza/android-use/main/install.sh | bash
   

2. Installed structure:

   • ~/.config/opencode/skill/android-use/SKILL.md
   • ~/.config/opencode/skill/android-use/scripts/android-use
   • ~/.config/opencode/skill/android-use/references/
   • ~/.config/opencode/skill/android-use/assets/
   • ~/.config/opencode/skill/android-use/repo/

3. Verify installation:

   ~/.config/opencode/skill/android-use/scripts/android-use check-device
   

Quick Start

android-use check-device        # List connected devices
android-use get-screen          # Get UI hierarchy (compact JSON)
android-use tap 540 960         # Tap at coordinates
android-use type-text "Hello"   # Type text
android-use key HOME            # Press key
android-use screenshot ./screen.png  # Capture screen

Core Agent Workflow

STEP 1: Check device

android-use check-device

• Lists all connected devices
• Note the serial number if multiple devices
• For "phone" use [PHYSICAL] device
• For "emulator" use [EMULATOR] device

STEP 2: Get screen state

android-use get-screen

• Returns compact JSON with pre-calculated tap coordinates
• Search for: text, contentDesc, resourceId
• Use the center field for coordinates (e.g., "center": [540, 289])
• Cache location: /tmp/.ai-artifacts/skills/android-use/screen.json

STEP 3: Execute action

• Tap: android-use tap <center_x> <center_y>
• Type: android-use tap <field_x> <field_y> then android-use type-text "text"
• Swipe: android-use swipe <x1> <y1> <x2> <y2> [duration_ms]
• Key: android-use key <KEY_NAME> (HOME, BACK, ENTER, etc.)

STEP 4: Verify and repeat

• Run get-screen again to verify state change
• Handle any dialogs that appeared
• Repeat until goal achieved

Reading Screen Data

Compact JSON (default): get-screen outputs pre-calculated tap coordinates and filtered elements (99% smaller than XML):

{
  "elements": [
    {
      "text": "Settings",
      "resourceId": "com.android.settings:id/title",
      "contentDesc": "",
      "clickable": true,
      "scrollable": false,
      "focused": false,
      "bounds": [42, 234, 1038, 345],
      "center": [540, 289]
    }
  ],
  "clickable": [...],
  "scrollable": [...],
  "withText": [...],
  "withContentDesc": [...]
}

Key attributes:

• text - Visible text
• contentDesc - Accessibility description (icons)
• resourceId - Element identifier
• clickable / scrollable - Interaction states
• center - Pre-calculated tap coordinates [x, y]
• bounds - Original bounds [left, top, right, bottom]

Use pre-calculated center:

• Already calculated: tap 540 289 (no manual math needed)

Full XML (when needed):

• Use get-screen --full for raw XML
• Saves to /tmp/.ai-artifacts/skills/android-use/screen.xml

Cache location (memory-backed):

• /tmp/.ai-artifacts/skills/android-use/screen.json (compact)
• /tmp/.ai-artifacts/skills/android-use/screen.xml (full)

Key Names

HOME, BACK, MENU, POWER, ENTER, TAB, DEL, ESCAPE, VOLUME_UP, VOLUME_DOWN, DPAD_UP, DPAD_DOWN, DPAD_LEFT, DPAD_RIGHT

Multi-Device Support

When multiple devices connected:

1. Run check-device to see all devices with types
2. User says "phone/physical" -> use [PHYSICAL] device
3. User says "emulator" -> use [EMULATOR] device
4. Pass -s <serial> to ALL subsequent commands

android-use check-device
# Multiple devices connected (2):
#   [PHYSICAL] 1A051FDF6007PA - Pixel 6
#   [EMULATOR] emulator-5554 - sdk_gphone64_arm64

android-use -s 1A051FDF6007PA get-screen
android-use -s 1A051FDF6007PA tap 540 960

Common Patterns

Tap a button

android-use get-screen              # Get JSON with pre-calculated centers
# Search JSON for button, find center: [540, 289]
android-use tap 540 289             # Tap at center

Enter text in field

android-use tap 540 184             # Focus field
android-use type-text "search term"
android-use key ENTER               # Submit

Scroll to find content

android-use get-screen              # Check if visible
android-use swipe 540 1500 540 500  # Swipe up (scroll down)
android-use get-screen              # Check again

Handle dialogs

# Look for "OK", "Allow", "Accept" buttons in XML
android-use tap <button-center>
# Or dismiss with back
android-use key BACK

Open app and navigate

android-use launch-app com.android.chrome
android-use get-screen
# Find URL bar, tap it
android-use tap 540 184
android-use type-text "example.com"
android-use key ENTER

JSON Output

Use --json for structured output:

android-use --json check-device

{
  "success": true,
  "exitCode": 0,
  "data": { "devices": [...], "count": 1 },
  "message": "Found 1 device(s)",
  "trace": { ... }
}

Error Handling

• No device: Check USB, verify USB debugging enabled, accept "Allow USB debugging?" prompt
• Element not found: Get fresh screen dump, try scrolling
• Action didn't work: Add minimal delay (300ms max) only if retrying, then verify coordinates, check for popups/dialogs, get fresh screen dump
• Device offline: Reconnect USB, run adb kill-server && adb start-server

Agent Best Practices

1. Always get-screen first - understand current UI state
2. No artificial delays needed - Commands execute synchronously; UI is ready for next command immediately
3. Check your work - get-screen after each action to verify
4. Use screenshots - when JSON doesn't capture enough info
5. Be consistent - use same serial for all commands in session
6. Compact JSON default - 99% smaller, pre-calculated tap coords, cached to /tmp/.ai-artifacts/skills/android-use/
7. Handle dialogs - popups often block interactions
8. Use center coordinates - from JSON output, no manual calculation needed

Compact JSON Filter Logic

The compact JSON includes elements with ANY of:

• Non-empty text (visible labels)
• Non-empty contentDesc (accessibility descriptions)
• clickable = true (interactive elements)
• scrollable = true (scrollable containers)

This filters ~336 raw nodes → ~55 useful elements (4x smaller)
