How do I access a Java static method on a Kotlin subclass?

Question

I\'ve created a Kotlin subclass of a Java class:

class AlarmReceiver : WakefulBroadcastReceiver() {

    companion object {
        const val ACTION_NOTIFY =         


        

Answer 1

In Kotlin, unlike Java, static members are not inherited by subclasses, even though they can be called inside a subclass without the base class name.

Outside a subclass, you have to call the base class static functions using the base class name:

WakefulBroadcastReceiver.completeWakefulIntent(intent)

This behavior seems to lie within the companion objects concept: companion objects of classes in a hierarchy are not included into each other.

_{Interestingly, for interfaces the situation is a bit different: interface static members cannot be referenced in subclasses without the interface name. This behavior is the same to that in Java.}
