AppCompatActivity

constructor()(source)

Default constructor for AppCompatActivity. All Activities must have a default constructor for API 27 and lower devices or when using the default android.app.AppComponentFactory.

constructor(@LayoutRes contentLayoutId: Int)(source)

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

This should generally be called from your constructor that takes no parameters, as is required for API 27 and lower or when using the default android.app.AppComponentFactory.
