Do I have to change something in order for butterknife work with kotlin ? I am getting this err : Caused by: kotlin.UninitializedPropertyAccessException: lateinit property introIndicator0 has not been initialized
@BindView( R.id.imageview_welcome_intro_indicator_0) lateinit var introIndicator0: ImageView

Did you forget to call
ButterKnife#bind
?

I have it inside the BaseActivity

Perhaps you are attempting to use the variable before the base activity has had the chance to initialize it then
Also, did you change
annotationProcessor
in Gradle to

There lies the problem then. Kotlin has it’s own annotation processor that should be applied instead of Android’s

kapt
and apply the kapt plugin.
apply plugin: kotlin-kapt
