I have a specific scenario where I make a POST request with a unique ticket in the body to get a resulting page back.
The resulting page is either Content-Type: application/pdfor text/html. The ticket is only valid once, so the page can only be loaded once.
Problem is that Android WebView does not support rendering of pdf (as the equivalent on iOS do).
I've tried the following:
-
Check http response headers with a primary request and then download the file with a second request if it's a pdf and open it in a PDF app (works). But for loading html pages, the second request fails, since the ticket is no longer valid.
-
Download both the pdf and the html page and then open in pdf app/WebView locally. This works, both relative links in the web pages is broken. Is there a nice way to download them as well?
x. Is it possible to interrupt the request in the WebView to read the response headers and trigger a download if it's a pdf otherwise just continue rendering? Can't find a good answer for this.
from Android WebView: Download when content-type is appliaction/pdf and render web page when not
