Unresolved reference: BR (Android Studio)

Question

My top level build.gradle:

buildscript {
    ext.kotlin_version = \'1.2.41\'
    ext.lifecycle_version = \"1.1.1\"
    repositories {
        google()
               


        

Answer 1

For Android Studio 3.3, Gradle 3.3.0 and Databinding v2, the only line that needs to be added to fix this issue is in your (app's or modules) build.gradle:

apply plugin: "kotlin-kapt"
