Hello, about a year has passed since this post but I think I found the solution for your problem aquinn
I just put the font type .eot (embedded open type) generated with Fontsquirrel's generator, put those files and CSS inside Construct. Then exported the project for Cordova using new intel xdk project format. And from Intel XDK generated the apk and no problems loading the font
I had tried lots of times with the other types (ttf, woff, woff2, svg) but then I realized that eot was embedded so I tried that one and it worked!
