	 * The purpose of this method is to delete the previously prepared user resources.
	 * The content of the `<platforms>/android/.../res` directory is based on user's resources and gradle project template from android-runtime.
	 * During preparation of the `<path to user's App_Resources>/Android` we want to clean all the users files from previous preparation,
	 * but keep the ones that were introduced during `platform add` of the android-runtime.
	 * Currently the Gradle project template contains resources only in values and values-v21 directories.
	 * So the current logic of the method is cleaning al resources from `<platforms>/android/.../res` that are not in `values.*` directories
	 * and that exist in the `<path to user's App_Resources>/Android/.../res` directory
	 * This means that if user has a resource file in values-v29 for example, builds the project and then deletes this resource,
	 * it will be kept in platforms directory. Reference issue: `https://github.com/NativeScript/nativescript-cli/issues/5083`
	 * Same is valid for files in `drawable-<resolution>` directories - in case in user's resources there's drawable-hdpi directory,
	 * which is deleted after the first build of app, it will remain in platforms directory.
