ASSET_LOADER_DUMMY_DOMAIN
A dummy domain used by the AssetLoader for local items. Instead of "file:///", Braze will have the HTML reference this domain for local files. InAppMessageHtmlBaseView.setWebViewContent and InAppMessageWebViewClient.assetLoader should both use this value. Do not use your own value since it is used internally by Braze for HTML In-App messages with a zip file.
