Android Jetpack: Sweetening Kotlin development with Android KTX
summary
Android KTX turns existing Android APIs into concise Kotlin idioms by shipping curated sibling artifacts (now Core-KTX 1.0 Alpha 1 and KTX modules for fragment, navigation, work, SQLite), rewriting trivial extensions to delegate to Java utilities (ColorUtils) and defaulting to inline + reified where it avoids allocations. Extensions are inline unless they allocate; some implementations move upstream into core. A KEEP proposal (now submitted as KEEP-110 annotations) targets annotating Java APIs so Kotlin can treat static methods, defaults and names as true extensions.
