/// NDK libraries are by default accessible and therefore don't require the
/// `<uses-native-library>` tag.

/// Non-NDK native shared libraries that are provided by silicon vendors or device
/// manufacturers are not accessible by default if the app is targeting Android 12
/// or higher. The libraries are accessible only when they are explicitly requested
///  using the `<uses-native-library>` tag.

/// ## Installation
/// If this element is present and its android:required attribute is set to true,
