What operating system does Kotlin is compatible of?

Short summary: Kotlin 1.3 discontinues the following deprecated binary artifacts : kotlin-runtime : use kotlin-stdlib instead. kotlin-stdlib-jre7/8 : use kotlin-stdlib-jdk7/8 instead. kotlin-jslib in the compiler distribution: use kotlin-stdlib-js instead.

Kotlin is fully compatible with JDK 6 , is supported in the Android Studio and compatible with the Android build system. Apps written in Kotlin are more productive than Java apps.

Backward Compatibility The Android SDK is by default forward compatible but not backward compatible — this means that an app that is built with and supports a minimum SDK version of 3.0 can be installed on any device running Android versions 3.0 and upwards — but not on devices running Android versions below 3.0.
