Isn’t the error pretty meaningful?
You try to access property ndkVersion on extension android, but it does not exist.

My general recommendation is to use Kotlin DSL instead of Groovy DSL,
becaues then you get statically typed type-safe build scripts immediately,
along with amazingly better IDE support.

Thank you very much for your help. I am at the beginning in this field. how should i switch to kotlin dsl?
