Specs

The current minSDK version for the SDK is 24. This corresponds to Android version 7.0 aka Nougat; released in 2016 and official support was stopped in 2019. This provides coverage for most android devices.

The current compileSdk and targetSdk are 36 corresponding to Android version 16; released in March 2025.

The SDK is currently compiled with Kotlin 2.2.21. We encourage implementors to use the same version, but the lowest supported version is 2.0.0. Active support for version 1 of kotlin was ended by JetBrains in 2024. Versions older than 2.0.0 are not supported due to technical constraints with how android dependencies work.
