Kotlin-android: unresolved reference databinding

Question

I have following fragment class written in Java using the new databinding library

import com.example.app.databinding.FragmentDataBdinding;

public class Data         


        

Answer 1

In my case, adding

kapt {
    generateStubs = true
}

Solved the problem for me. I ignored it the first time, I thought it's irrelevant to the problem:

Unresolved reference databinding

But now, data-binding is working just fine.

Answer 2

this work for me in androidStudio ver3.1.3

apply plugin: 'kotlin-kapt'

dataBinding {
    enabled = true
}

Answer 3

Update 2: This is a really old answer, instead refer to lrampazzo's answer.

It works with 1.0-rc4, put

kapt 'com.android.databinding:compiler:1.0-rc4' 

into your dependencies

Thanks Ghedeon, for the link in comments

Update: Here's a really simple hello world example project

Answer 4

I want to share my own expirience. To use data databinding with Kotlin in android studio is enough to add

dataBinding {
    enabled = true
}

After that "sync it" and, it's very important, to "make Project". After that all your object will be active to use.
