Cutting-Edge-to-Edge in Android 15
summary
Android 15 forces edge-to-edge so apps must handle window insets; this session shows concrete fixes in Jetpack Compose: use WindowInsetsPadding and consumeWindowInsets to avoid double padding, convert insets to PaddingValues for LazyColumn, add a gradient when content scrolls under the status bar, and handle landscape/gesture vs button navigation. Demonstrations include a Maven Central library to simulate window insets in previews, an alpha Google tool compose preview screenshot testing for JVM screenshots, and a GitHub test helper with window inset assertions that runs 256 configuration permutations.
