Build apk using build.phonegap white page

hello. i want to learn framework7, i have make a new project from framework7 app html layout, and i have built the apk with using buil.phonegap. i ran the apk with nox player, why the result is white page?

this is my-app.js file
var app = new Framework7({
// App root element
root: ‘#app’,
// App Name
name: ‘My App’,
// App id
id: ‘com.myapp.test’,
// Enable swipe panel
panel: {
swipe: ‘left’,
// Add default routes
routes: [
path: ‘/about/’,
url: ‘about.html’,
// … other parameters

var mainView = app.views.create(’.view-main’);

Sorry for my bad english, thanks…

url string Default (initial) View’s url. If not specified, then it is equal to document url

you didnt share the full app. but try changing the view creation

var mainView = app.views.create(’.view-main’, {url: '/about/'});
