Doesn't save thumbnails of recently viewed like like Shelf does. You open the app and get a blank screen. From there, after you click the icon, you likely need to be well-organized with your items in a folder. On the other hand, if you go to the stacked 3-horiz bar icon, you get easy access to Google Drive, and other locations.

What is Secure PDF Viewer?
Simple Android PDF viewer based on pdf.js and content providers. The app doesn't require any permissions.
The PDF stream is fed into the sandboxed WebView without giving it access to content or files. Content-Security-Policy is used to enforce that the JavaScript and styling properties within the WebView are entirely static content from the apk assets. It reuses the hardened Chromium rendering stack while only exposing a tiny subset of the attack surface compared to actual web content. The PDF rendering code itself is memory safe with dynamic code evaluation disabled, and even if an attacker did gain code execution by exploiting the underlying web rendering engine, they're within the Chromium renderer sandbox with no access to the network (unlike a browser), files, or other content.








Comments and Reviews
For just looking at pdf's, this works surprisingly well. Like, I generally prefer it to apps that do more. Think of it as the minimalist option for when you're just trying to read something that isn't an ebook.

Works perfectly well, plus, it’s THE most lightweight pdf viewer. Kudos to the Graphene OS team for bringing it to non-Pixel devices!
