Greetings! I've installed KOReader (koreader-android-arm-v2020.08.1.apk) on my updated Mars reader, and have only a few issues that I'd like to resolve. I'm not totally inept with code, so if solving these issues means getting the appropriate KOReader source, building and testing, I'd consider this route.
I'm using KOReader as a reader of a Calibre library on an SD card with directory structure defined by the plugboard script:
{author_sort[0]}/{author_sort:sublist(0,1,&)}/{series}/{series_index:0>4.1f|| - }{title}
e.g. /storage/sdcard_name/Books/R/Rowling, J.K./Harry Potter/01.0 - Harry Potter and the Sorcerer's Stone.epub
I've found two issues with KOReader, one in navigation and one in rendering:
- I have not gotten KOReader to use the Calibre metadata file on the SD card for searching. I've tried to edit a few .lua files to no avail, and much of the documentation floating around the MobileRead fora seems a bit out of date, or perhaps directed at the Kobo platform and not Android. How do I get KOReader on Android to use metadata.calibre?
- Certain rendering within an epub seems flaky. Not all covers are expanded to fill the screen, though they render correctly on other readers. Also, some small images (e.g. a "triple asterisk" .jpg used as a transition marker) render with a full width gray background instead of a transparent background.
Have other users noticed these issues? In any case, how can I fix them (or otherwise contribute)? I REALLY LIKE the way KOReader works generally, and love the way it renders epub text.
