Why does studio autofill generates a nullable bundle for onRestoreInstanceState?

override fun onRestoreInstanceState(savedInstanceState: Bundle?) {
        super.onRestoreInstanceState(savedInstanceState)
    }

It'll do this until they label it

@NotNull

in the code. If you're using support libs 27+ I believe they updated it so you'll have not null Bundle

Got it, fwiw, i'm on androidx1.0.0 so yeah it still is the case

Oh really? And you're extending

AppCompatActivity

?

Yup, cmd+b still takes to java version of it

AndroidX is not full Kotlin at all, it is Java, with Kotlin extensions if you use ktx. Do you use SDK 28+?

Was on 28.0.0 before migrating to AndroidX

@Sam

28.0.0

is not an Android SDK version

Oh do you meant target version?

compileSdk

that is 28
