I have just added your project in my gradle and it throws me this error during the sync:

I think you have not included your own xml layout attributes

Is there a solution for this error ?

@ncherian What I have done.

I have forked this project and added my fork as gralde module in my android project. Then in my main gradle (app module) I have added this inside android:

dataBinding {
    enabled = true
}

Worked with Android Studio pre 3.0. Now i face this error:
Did anyone come up with a solution?

Error:Execution failed for task ':app:compileReleaseJavaWithJavac'.

in date_time_range_picker.xml just changed:

xmlns:app="http://schemas.android.com/apk/res-auto"
to:
xmlns:app="http://schemas.android.com/apk/lib/xxx.yyy.zzz"

xxx.yyy.zzz is your package name
