FragmentActivity

open class FragmentActivity : ComponentActivity, ActivityCompat.OnRequestPermissionsResultCallback, ActivityCompat.RequestPermissionsRequestCodeValidator(source)

Base class for activities that want to use the support-based Fragments.

Known limitations:

  • When using the <fragment> tag, this implementation can not use the parent view's ID as the new fragment's ID. You must explicitly specify an ID (or tag) in the <fragment>.
