---

Activity used to run @Composable previews from Android Studio.

The supported @Composable functions either have no parameters, or have only parameters with default values and/or one parameter annotated with @PreviewParameter.

The @Composable fully qualified name must be passed to this Activity through intent parameters, using composable as the key. When deploying Compose Previews with @PreviewParameter annotated parameters, the provider should be specified as an intent parameter as well, using the key parameterProviderClassName. Optionally, parameterProviderIndex can also be set to display a specific provider value instead of all of them.
