	// _logger.LogDebug("Setting MaxBreadcrumbs: {0}", options.MaxBreadcrumbs);
	// androidManifest.SetMaxBreadcrumbs(options.MaxBreadcrumbs);
	// _logger.LogDebug("Setting MaxCacheItems: {0}", options.MaxCacheItems);
	// androidManifest.SetMaxCacheItems(options.MaxCacheItems);
	// _logger.LogDebug("Setting SendDefaultPii: {0}", options.SendDefaultPii);
	// // androidManifest.SetSendDefaultPii(options.SendDefaultPii);
