When using Jetpack Compose, by default it extends the ComponentActivity class. But after trying some samples I switched to AppCompatActivity and everything seemed to work fine. So I wonder what the difference between these is. Do any additional features come with ComponentActivity?
AppCompatActivity extends FragmentActivity which extends ComponentActivity.
ComponentActivity has all you need for a Compose-only app.
If you need AppCompat APIs, an AndroidView which works with AppCompat or MaterialComponents theme, or you need Fragments then use AppCompatActivity.
Note: it requires at least the AppCompat 1.3.0 version.
