The first Activity doesn't launch nevertheless Bundle?
.
class FirstActivity : Activity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
}
}
Caused by: java.lang.IllegalArgumentException: Parameter specified as non-null is null: method kotlin.jvm.internal.Intrinsics.checkParameterIsNotNull, parameter bundle
This error should occur when override fun onCreate(savedInstanceState: Bundle)
However, I fixed override fun onCreate(savedInstanceState: Bundle?)
That's error occurred at Application class, not Activity.
Need to change Bundle into "Bundle?" both Activity and Application class.
override fun onActivityCreated(activity: Activity, bundle: Bundle?) {
}
override fun onActivitySaveInstanceState(activity: Activity, bundle: Bundle?) {}
I had same error when i exchange .java to .kt automatically. But the real wrong point wasn't in Activity. In my case, the wrong place was ActivityLifecycleCallbacks where some parameters missing '?' in exchanging.
Wrong:
override fun onActivityCreated(activity: Activity, savedInstanceState: Bundle)
override fun onActivitySaveInstanceState(activity: Activity, outState: Bundle)
Correct:
override fun onActivityCreated(activity: Activity, savedInstanceState: Bundle?)
override fun onActivitySaveInstanceState(activity: Activity, outState: Bundle?)
