Could you please explain what your PDF Viewer requires network permission for? The app description does not tell, neither does your Readme here. Thanks in advance!

Issue Summary

Since version 3.5 (which I installed from F-Droid), this app opens the file browser in an unexpected manner. I have seen this happen in the following two scenarios:

1. on rotation of the device, i.e. switching between portrait and landscape mode;
2. upon attempting to open a PDF file from the File Manager installed on my phone.

Moreover, in scenario 1, if I open the same file again, and then go back with the intention to exit from the app, it brings me back to the same file, as if it had been opened twice and stacked on itself.

Version 3.4 works as intended, without this issue.

Steps to Reproduce the Problem

Scenario 1:

1. Make sure your device is set to switch between portrait and landscape mode when rotating it;
2. Open any PDF file in the file browser embedded in this app;
3. While the PDF is showing, rotate your device; Expected result: the PDF file is still shown in the alternate view (portrait or landscape, corresponding to how you're holding your device). Obtained result: the app shows the file browser.

Scenario 2:

1. Start a file manager app in your device;
2. Select a PDF file; if more PDF viewers are installed and you're prompted to select an app to open the PDF file, choose this app. Expected result: the PDF file is shown immediately, without going through the file browser. Obtained result: the app shows the file browser.

It was totally my fault for not checking before the merge, but the change done here prevents the bottom bar from changing colors as Cyanea changes the theme. For now I have reverted that line back.

Hello! A full screen mode/read mode would be a nice feature. For example, you tap once at the PDF and the toolbar on top of the pdf, the navigation bar and the status bar disappears (or appears if the full screen mode is enabled). Or toolbar, navigation bar and status bar disappear automatically after a few seconds.

Its only a wish/suggestion. I dont know how much work it is.

Thanks a lot for your work until now :smiley: :+1:

Awesome app, The last thing I need before I finally can ditch the last google app on my device (google PDF viewer) is printing.

In google PDF viewer I can print over the printers already added to my android system (so I guess this is native) Can we implement this here?

A dark mode would be nice. So that PDF is white text on black background. Maybe inverting does the trick. I know, that there is an invert option in the OS, but this is way too inconveniant.

Hi. Spanish translation is ready to merge. I also fixed some minor issues with values in "untranslatable" entries.

Let me know if everything is ok. Have fun.

Hi! First of all I would want to thank you for developing this great PDF viewer.

I have a suggestion, I think it would be helpful to have a list of the last opened files in the main screen instead of the lorem ipsum sample file. What do you think about it?

Issue Summary

App crashes when opening bigger files

Steps to Reproduce the Problem

Open a PDF of ~1MB of size. Scroll Flip orientation by 90° Crash

Issue Summary

It would be nice if you could implement the table of contents feature in the app, it's easier to navigate through a long document.

Steps to Reproduce the Problem

Issue Summary

If you zoom out at its minumum and scroll to the first page, you'll notice that the page number will be 2 instead of 1. It is similar for the last page, showing N-1 instead of N

Steps to Reproduce the Problem

Zoom out, scroll to either the last or first page

I am going though apps that use old native libraries on F-Droid: https://gitlab.com/fdroid/fdroiddata/-/merge_requests/11496/

Your app uses com.github.barteksc:android-pdf-viewer:3.2.0 using PDFium@32b639d from 2016-01-14, which seems to have ~55 known security issues. https://github.com/JavaCafe01/PdfViewer/blob/v3.7/app/build.gradle#L79

Newer versions do not seem to be available.

Currently there's a fixed limit to the zoom level. https://github.com/JavaCafe01/PdfViewer/blob/d6d909859cbfdaa4180cc2ca387951122128cedb/app/src/main/java/com/gsnathan/pdfviewer/MainActivity.java#L265

It would be great to remove this limit, or add an option to disable it.

Why

I'm trying to view a high resolution (vector) public transport map, and the maximum zoom is nowhere near enough zoom. Most of the text isn't readable even if I squint my eyes, as it's intended for much more zoom.
