## What it is
SwissArmyKnife is an Android UI debugging library that overlays view information directly on the device screen, such as text size, colors, margins, paddings, view dimensions, and Activity/Fragment names. It supports picking views, measuring distances between views, dragging views, and a screen color picker.

## Use cases
- inspect android view properties on device
- measure distance between two android views
- pick a color from the android screen
- show margins and paddings of views on screen
- identify current activity and fragment names
- drag views to test layouts

## When to choose
- debugging android UI layouts directly on a device or emulator
- you need on-screen view metrics like dp/px sizes, margins, and text attributes
- you want to identify which Activity or Fragment is currently displayed

## When to avoid
- you need automated UI tests rather than manual visual debugging
- your project targets Android versions below 5.0
- you need a desktop-based layout inspector like Android Studio's Layout Inspector
