Unable to run Angular2 application in Android WebView API 21

Question

I am trying to load an Angular2 application in an Android hybrid app which uses WebView. The SDK version is 21.

I am not able to load the app. It is not able to load boot.js module.

        Errormessage: "undefined is not a function↵ 
Error loading http://example.com/mobile/boot.js"stack:

It seems to be a problem with the compatibility of SystemJS with the WebView that I am using. Has anyone encountered the same issue?

添加SystemJS polyfills对我有用。
