Kotlin is a statically-typed programming language that works seamlessly with Android by compiling to the Java bytecode that runs on the Android runtime. It is fully interoperable with Java, allowing developers to use both languages within the same project. Kotlin simplifies Android development with features like null safety, extension functions, and concise syntax, which reduces boilerplate code and minimizes runtime errors. Google officially supports Kotlin for Android development, and it's integrated into Android Studio, making it easy to write, debug, and deploy Android apps using Kotlin.
