 * Classes with native methods (contain @NativeMethods interfaces) that are used within renderer
 * processes must be annotated with with @MainDex in order for their native methods work.

 * Applies only for Chrome/ChromeModern (not needed for Monochrome+).
 *
 * For Cronet builds, which use a default_min_sdk_version of less than 21, this annotation also
