DuoPlus CloudPhone Agent

Control and automate DuoPlus cloud phones using ADB broadcast commands.

For more information, visit DuoPlus Official Website.

Connecting Devices

Wireless Connection

adb connect <IP>:<PORT>
adb devices -l

All subsequent commands use -s <DEVICE_ID> to target a specific device.

Common Workflows

Launching an App

scripts/send_command.sh <DEVICE_ID> '{"action_name":"OPEN_APP","params":{"package_name":"com.tencent.mm"}}'

Analyzing the UI

Dump and pull the UI hierarchy to find element coordinates and attributes:

adb -s <DEVICE_ID> shell uiautomator dump /sdcard/view.xml && adb -s <DEVICE_ID> pull /sdcard/view.xml ./view.xml

Then grep for text or resource IDs to find bounds="[x1,y1][x2,y2]".

Interacting with Elements

All interactions are sent via the helper script as JSON commands:

• Tap coordinate: scripts/send_command.sh <DEVICE_ID> '{"action_name":"CLICK_COORDINATE","params":{"x":500,"y":500}}'
• Tap element by text: scripts/send_command.sh <DEVICE_ID> '{"action_name":"CLICK_ELEMENT","params":{"text":"Login"}}'
  • Optional params: resource_id, class_name, content_desc, element_order (0-based index)
• Long press: scripts/send_command.sh <DEVICE_ID> '{"action_name":"LONG_COORDINATE","params":{"x":500,"y":500,"duration":1000}}'
• Double tap: scripts/send_command.sh <DEVICE_ID> '{"action_name":"DOUBLE_TAP_COORDINATE","params":{"x":500,"y":500}}'
• Type text: scripts/send_command.sh <DEVICE_ID> '{"action_name":"INPUT_CONTENT","params":{"content":"Hello","clear_first":true}}'
  • Must tap the input field first to focus it
• Keyboard key: scripts/send_command.sh <DEVICE_ID> '{"action_name":"KEYBOARD_OPERATION","params":{"key":"enter"}}'
  • Supported keys: enter, delete, tab, escape, space
• Swipe: scripts/send_command.sh <DEVICE_ID> '{"action_name":"SLIDE_PAGE","params":{"direction":"up","start_x":487,"start_y":753,"end_x":512,"end_y":289}}'
  • direction: up/down/left/right (required). Coordinates are optional.
• Home: scripts/send_command.sh <DEVICE_ID> '{"action_name":"GO_TO_HOME","params":{}}'
• Back: scripts/send_command.sh <DEVICE_ID> '{"action_name":"PAGE_BACK","params":{}}'
• Wait: scripts/send_command.sh <DEVICE_ID> '{"action_name":"WAIT_TIME","params":{"wait_time":3000}}'
• Wait for element: scripts/send_command.sh <DEVICE_ID> '{"action_name":"WAIT_FOR_SELECTOR","params":{"text":"Loading complete","timeout":10000}}'
• End task (only when stuck): scripts/send_command.sh <DEVICE_ID> '{"action_name":"END_TASK","params":{"success":false,"message":"reason"}}'

All action commands are fire-and-forget — they do NOT return results. Take a screenshot after each action to verify.

Visual Verification

Take a screenshot, compress with cwebp, and pull to local for analysis:

# Take screenshot on device
adb -s <DEVICE_ID> shell screencap -p /sdcard/screen.png

# Pull to local
adb -s <DEVICE_ID> pull /sdcard/screen.png ./screen.png

# Compress to WebP for smaller file size (optional, recommended for vision model)
cwebp -q 60 -resize 540 0 ./screen.png -o ./screen.webp

If cwebp is not available, use the PNG directly.

How Commands Work (Internal)

Commands are sent as Base64-encoded JSON via ADB broadcast. The helper script scripts/send_command.sh handles this automatically:

# Usage: scripts/send_command.sh <DEVICE_ID> <ACTION_JSON>
scripts/send_command.sh 192.168.1.100:5555 '{"action_name":"CLICK_ELEMENT","params":{"text":"Login"}}'

The script builds the full payload (task_type, task_id, md5, etc.), Base64-encodes it, and sends via:

adb -s <DEVICE_ID> shell am broadcast -a com.duoplus.service.PROCESS_DATA --es message "<BASE64>"

Typical Workflow

1. Analyze UI    → uiautomator dump to find elements, or screenshot for visual analysis
2. Execute action → send_command.sh with the appropriate action JSON
3. Wait 1-3s     → Let the action take effect
4. Verify        → Screenshot + cwebp compress, or uiautomator dump again
5. Repeat 2-4 until all requested steps are completed

Tips

• Coordinates: The coordinate system is 0-1000 relative (top-left=0,0, bottom-right=1000,1000), NOT pixels.
• Element matching: Use CLICK_ELEMENT (by text) when possible; fall back to CLICK_COORDINATE when text matching fails.
• Input: Must tap the input field first (CLICK_COORDINATE or CLICK_ELEMENT) to focus, then INPUT_CONTENT.
• Submit: After typing, use KEYBOARD_OPERATION(key="enter") to submit.
• Wait: Use sleep 1-3 between commands to allow the UI to update. Do NOT use shell sleep on the device.
• Swipe coordinates: Must use irregular integers, avoid round numbers (500, 800). Vary coordinates between consecutive swipes.
