ext {
buildToolsVersion = "31.0.0"
minSdkVersion = 21
compileSdkVersion = 31
targetSdkVersion = 31
kotlinVersion = "1.5.31" //use this line -----------
if (System.properties['os.arch'] == "aarch64") {
// For M1 Users we need to use the NDK 24 which added support for aarch64
ndkVersion = "24.0.8215888"
} else {
// Otherwise we default to the side-by-side NDK version from AGP.
