[Feature request] Ability to open PDFs through URLs about pdfviewer HOT 10 OPEN

I can work on implementing this feature

from pdfviewer.

Conspiracy theory: Google broke things so only their Drive app could have this functionality. 👀

Just did some testing and it appears it already works in Android 6, but something changed in Android 7 that prevents it from working

from pdfviewer.

Actually that functionality work, I implemented it some months ago... Well maybe it doesn't work for everything, can you tell us from which app the link come from ?

To test I use an Android 9 phone and open a link to a PDF from Firefox to PdfViewer and it work perfectly...

Is there only a problem on Android 7 ? :(

Ah. A little more testing done.

I was using Fenix to try and share a link to PDF Viewer, but it doesn't show up in the Share Sheet. That threw me off, since Librera does show up. Could that be added?

Using Firefox for Android's 'Open in App' feature does indeed work, but it downloads the file permanently. I was hoping for it to be cached, and deleted upon closing PDF Viewer. Is that feasible?

(Google Drive's PDF Viewer also has an option to permanently save a cached PDF if you feel like it, though that might amount to feature creep, since it can be downloaded separately anyway. Still would be nice to have. ^_^ )

I was testing Google chrome and it didn't work, perhaps there's no fix since there's no way on android 7+ to get the os to detect that it can open files without download

from pdfviewer.

If it works for Google Drive, there must be a way, mustn't there?

from pdfviewer.

Google Drive is a file explorer app (which the open with feature already works with), Google Drive likely downloads the file and then opens it in the app you choose

from pdfviewer.

Sure. The file cannot be shown without being downloaded, even for desktop browsers. But they store it in a temp directory and then either delete it or it gets cleaned up with a restart.

Google Drive has an inbuilt PDF viewer (see OP) which directly downloads the PDF (temporarily) and shows it. The main app has no role (unless you choose to save the PDF to Drive) and you can use this PDF Viewer activity as a standalone.

Wait, I just discovered that the print button has a Save to PDF option. All I need now is for the PDF to be temporarily cached instead of downloaded for viewing.
