Stop guessing why your Android UI is overlapping. Learn how to use the Layout Inspector's 3D mode and live attribute tracking to find and fix hidden layout bugs.
Use derivedStateOf to memoize filtered lists and UI flags in Jetpack Compose so recomposition only happens when the projected result actually changes, not on every source update.
Learn how to use Jetpack Compose's rememberSaveable to keep UI state like text field content or custom data objects alive across screen rotations and process death, with a worked example and verification steps.
Learn how to hoist UI state out of Jetpack Compose composables to make them pure, reusable, and easy to test, with a concrete counter‑button example and verification steps.

Learn how to use the Android Studio Layout Inspector to debug overlapping UI elements and analyze view hierarchies in real-time for XML and Jetpack Compose.
Stop guessing why your Android UI is clipping or lagging. Learn how to use the Layout Inspector's 3D mode and Component Tree to debug nested hierarchies and overdraw in real-time.
Learn how hoisting state with remember and mutableStateOf keeps composables stateless, limits recomposition scope, and improves UI performance.
