unresolved reference: override (onCreate) - kotlin

Question

why is there an unresolved reference on override at the onCreate method? (Kotlin)
// unresolved reference: override
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
// MapFragment erstellen und anzeigen
startMapFragment()
mapFragment.getMapAsync(this)
// OnClickListener für SpeicherDetailActivity
btnDetailSpeichern.setOnClickListener {
val detailIntent = Intent(this, SpeicherDetailActivity::class.java)
startActivity(detailIntent)
}
}
I tried to clean and rebuild the Project.
I deleted the onCreate method and let AndroidStudio generate an new one (by pressing CTRL + O).
I copied an onCreate method from another Activitiy,
but nothing of this worked.
Here is the full Activity:
class SpeicherActivity : AppCompatActivity(), OnMapReadyCallback {
// Variablem für MapFragment erstellen
var mapFragment = MapFragment.newInstance()
var fragmentTransaction = fragmentManager.beginTransaction()
var muennerstand : Ort = Ort(20.0, 5.0, "Münnerstadt", "", 0.0f)
var standartMarker = MarkerOptions().position(LatLng(muennerstand.latitute, muennerstand.longitute)).title("standart")
// GPS TEST
val locManager = LocationManager.GPS_PROVIDER.
// unresolved reference: override
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
// MapFragment erstellen und anzeigen
startMapFragment()
mapFragment.getMapAsync(this)
// OnClickListener für SpeicherDetailActivity
btnDetailSpeichern.setOnClickListener {
val detailIntent = Intent(this, SpeicherDetailActivity::class.java)
startActivity(detailIntent)
}
}
// MapFragment erstellen und anzeigen
fun startMapFragment() {
fragmentTransaction.add(R.id.fragmentContainer, mapFragment)
fragmentTransaction.commit()
}
override fun onMapReady(mMap : GoogleMap?) {
mMap?.addMarker(standartMarker)
}
}

Answer 1

There is a syntax error in your code. Remove the full-stop at the end of the "locManager" variable declaration line. That should fix your issue.
// GPS TEST
val locManager = LocationManager.GPS_PROVIDER
