This is looks like advanced!
I am limited to Kodular only 
Html Error help me.
The error is referent pdf.workoer.js to path/url not existing (you path/url is for pc).
Upload pdf.workoer.js to your app project and into html code set link src=“pdf.workoer.js”
Or you referent to file strore in a server src=“https//…”
If there is a way to only load certain pages of a pdf file that would be great.
Deephost has an extension like that. I forgot where.
And now someone will flag me quickly because I talked about deephost 
But that does not have features. It has horizontal scroll to change page and if you pdf is of not same size as screen it sompress the pages and even shows landscape pages in portrait.

Yes off course.
Actually the problem is that there is no native library to render pdf in Android.Also a few libraries who has been ported from Java/IOS to Android are quite big in size.
Would anyone like to build app with an extension of 9mb in size? (I am talking about Pdfium).
