ComponentActivity

Kotlin |Java

open class ComponentActivity : ComponentActivity, ContextAware, LifecycleOwner, ViewModelStoreOwner, HasDefaultViewModelProviderFactory, SavedStateRegistryOwner, OnBackPressedDispatcherOwner, ActivityResultRegistryOwner, ActivityResultCaller

androidx.activity.ComponentActivity

Known Direct Subclasses

FragmentActivity

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

Known Indirect Subclasses

AppCompatActivity

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

Base class for activities that enables composition of higher level components.

Rather than all functionality being built directly into this class, only the minimal set of lower level building blocks are included. Higher level components can then be used as needed without enforcing a deep Activity class hierarchy or strong coupling between components.
