Problem with viewerjs

Hello, I’m trying to load a pdf in my website. I’m using viewerjs to solve this problem and it works for my laptop browser, but when i try this in an apk, it does not recognize the file and it does not work. I have checked that viewerjs works in chrome but not in native android browser (you can do the test open its website from an android device). Any solution?

Hi Antonio,
did you solve your problems with viewerjs?
Is it usable with Ionic3?
Or is there a better solution?

Thank you
