Answer 1

WebView is desired to show web content, not (PDF or any other format) document. this site you are opening is in fact a web app which can render PDF file as web content, so you are obtaining an iframe

you can find pleny of PDF-rendering libraries for Android, e.g. probably most common AndroidPdfViewer, but in THIS article you can find more alternatives
