AppCompatActivity

Kotlin |Java

open class AppCompatActivity : FragmentActivity, AppCompatCallback, TaskStackBuilder.SupportParentable, ActionBarDrawerToggle.DelegateProvider

androidx.activity.ComponentActivity
↳	androidx.fragment.app.FragmentActivity
	↳	androidx.appcompat.app.AppCompatActivity

Base class for activities that wish to use some of the newer platform features on older Android devices. Some of these backported features include:

Using the action bar, including action items, navigation modes and more with the setSupportActionBar(Toolbar) API.
Built-in switching between light and dark themes by using the Theme.AppCompat.DayNight theme and AppCompatDelegate#setDefaultNightMode(int) API.
Integration with DrawerLayout by using the getDrawerToggleDelegate() API.

Note that every activity that extends this class has to be themed with Theme.AppCompat or a theme that extends that theme.
