问题 We have a responsive web app developed using AngularJS 2. We would like to wrap it inside a package to redistribute it as a mobile app. Android is our priority. We have looked at Cordova. Are there other options available for turning a web app into a mobile app? What are the pitfalls involved in turning an AngularJS 2 web app into a mobile app? 回答1: Ionic 2, currently in beta, uses Angular2 to make hybrid mobile apps.
