UI Screenshot

This skill standardizes the process of capturing, retrieving, and organizing screenshots from Android devices for visual verification and documentation.

Workflow

1. Capture Screenshot

Use screencap on the device to save the framebuffer to a file.

adb shell screencap -p /sdcard/screenshot.png

2. Retrieval

Pull the screenshot file from the device to your local machine.

adb pull /sdcard/screenshot.png <local_destination_path>

Suggestion: Use a descriptive filename locally, e.g., login_screen_v2.png.

3. Cleanup

Delete the temporary file from the device to save space and keep it clean.

adb shell rm /sdcard/screenshot.png

One-Liner (PowerShell)

To capture, pull, and clean up in one go (replace local_filename.png):

adb shell screencap -p /sdcard/s.png; adb pull /sdcard/s.png ./local_filename.png; adb shell rm /sdcard/s.png

Verification Tips

• Ensure the device screen is on and displaying the target UI.
• Use adb shell input keyevent 82 to unlock screen if needed (depends on security settings).
• For automated UI testing screenshots, consider using instrumented tests (Espresso/UiAutomator), but for ad-hoc agent verification, this ADB method is fastest.
