Ionic App not running on Android Device

Question

I created my App Completely using my PC browser

when I did an Android Build and deploy on my Device it stays at a blank white screen.

So i decided to host the files in /www to debug.

I get the Error 0 619759 error Uncaught TypeError: Cannot read property '6' of undefined, http://10.12.1.205:8100/build/js/Reflect.js, Line: 894

20029 error Uncaught reflect-metadata shim is required when using class decorators, http://10.12.1.205:8100/build/js/app.bundle.js, Line: 36793
