| <p>Integration points with the Fragment host. </p> |
| <p> Fragments may be hosted by any object; such as an <code><a href="https://developer.android.com/reference/android/app/Activity.html">Activity</a></code>. In order to host fragments, implement <code><a href="/reference/kotlin/androidx/fragment/app/FragmentHostCallback.html">FragmentHostCallback</a></code>, overriding the methods applicable to the host. </p> |
| <p> FragmentManager changes its behavior based on what optional interfaces your FragmentHostCallback implements. This includes the following: </p> |
| <ul> |
| <li><b><code><a href="/reference/kotlin/androidx/activity/result/ActivityResultRegistryOwner.html">ActivityResultRegistryOwner</a></code></b>: Removes the need to override <code><a href="/reference/kotlin/androidx/fragment/app/FragmentHostCallback.html#onStartIntentSenderFromFragment(androidx.fragment.app.Fragment,android.content.IntentSender,int,android.content.Intent,int,int,int,android.os.Bundle)">onStartIntentSenderFromFragment</a></code> or <code><a href="/reference/kotlin/androidx/fragment/app/FragmentHostCallback.html#onRequestPermissionsFromFragment(androidx.fragment.app.Fragment,java.lang.String[],int)">onRequestPermissionsFromFragment</a></code>.</li> |
