ADB

Prerequisites
• Android device with USB debugging enabled (Settings → Developer options → USB debugging)
• USB cable and free USB port on your PC
• Android SDK Platform-Tools unzipped (e.g. C:\adb\platform-tools)
• Python 3 installed globally

Start ADB & confirm device
• Open PowerShell or CMD
• Change into your Platform-Tools folder:
cd C:\adb\platform-tools
• Run:
adb.exe start-server
adb.exe devices
• Verify your device serial appears under “List of devices attached.”

Install Python packages
• In any console window, run:
pip install --upgrade pip
pip install pure-python-adb numpy pillow

Prepare script & image
• Place your draw.py script in a folder, e.g.  (downloaded from https://gist.github.com/paciops/40c22ebd2d14aa330220a6d12731fcfa)
C:\path\to\draw.py
• Put your image file in a known location, e.g.
C:\path\to\your\image.jpg

Run the drawing script
• In PowerShell/CMD, execute:
python C:\path\to\draw.py C:\path\to\your\image.jpg
• Watch for console logs (“Connected to…”, “Total swipes…”) and the image being drawn on your device.

Troubleshooting
• No device listed: check cable, USB port and re-authorize USB debugging on the phone
• Permission denied on device.shell(...): revoke and re-allow USB debugging
• Swipes off-screen or invisible: print out mapped coordinates in your script and adjust screen_start_x, screen_start_y or scale
• ADB server errors:
adb.exe kill-server
adb.exe start-server
