KOreader on Android

Hi, if you're the author of https://github.com/koreader/koreader/issues/11319 please move questions there

Also, please do not trust random user patches unless they're github tickets with the tag "user patch available".

The best way to write your own patches is to read the source and understand specific parts of its behaviour to be able to change what you want to change.

In this case there're already a few places where we set a viewport in android devices: https://github.com/koreader/koreader...oid/device.lua

Use them as an inspiration.

And to not use the f-droid build, as patches are disabled there .

The previous version was working perfectly. Anything I can do? I'm wary of uninstalling as I want to retain my settings.

Thanks! Backed up and reinstalled, works now.

I'm suddenly getting "Something went wrong..." when trying to sync progress. WiFi is on. Is server down or do I have problems with my installation?

Stupid question: how do I send KOReader to the background? Must I exit everytime I want to use my phone for other tasks?

The app works in fullscreen but you should be able to swipe from top/bottom edges to display status bar and virtual buttons.

The swipe from top clashes a bit with KOReader default settings of invoking top menu. You can setup that to "tap only" in case you use the swipe gesture a lot to see your device notifications.

Thank you.

Is it possible zoom on pdfs with gestures? I have a Pocketbook Color 3 and it doesn't work as in built-in app, where I can adjust the zoom and move to sections of the pdf viewing the actions at the same time.

[Frenzie]

Not at this point.

Ok, but is there anyone working on it? I have a Pocketbook Inkpad Color 3 and zooming is hellishly slow, a pity because it runs Linux and could be better like on Kobos

Kobo also runs Linux. So that's not why your Inkpad Color 3 is slow.

Yes! It's my reason to install Koreader, but zoom by gestures is not implemented yet
