FragmentActivity

public class FragmentActivity extends ComponentActivity implements ActivityCompat.OnRequestPermissionsResultCallback

         ↳ android.app.Activity
           ↳ androidx.activity.ComponentActivity
             ↳ androidx.fragment.app.FragmentActivity
Known direct subclasses
AppCompatActivity

Base class for activities that wish to use some of the newer platform features on older Android devices.
BaseCarAppActivity

Core logic for CarAppLibrary Activity interaction with a host.
LauncherActivity

This class handles providing the right launcher activity when running native applications and Car App Library applications.
Known indirect subclasses
CarAppActivity

The class representing a car app activity in the main display.

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>.

Summary

Public constructors

Default constructor for FragmentActivity.
@ContentView
FragmentActivity(@LayoutRes int contentLayoutId)

Alternate constructor that can be used to provide a default layout that will be inflated as part of super.onCreate(savedInstanceState).

Public methods
void
dump(
    @NonNull String prefix,
    @Nullable FileDescriptor fd,
