FragmentActivity

open class FragmentActivity : ComponentActivity, ActivityCompat.OnRequestPermissionsResultCallback, RequestPermissionsRequestCodeValidator
androidx.activity.ComponentActivity
   ↳ androidx.fragment.app.FragmentActivity

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>.
