WHY NO REVIEW YET
TopGit writes full reviews for the most-starred, most-requested repositories. This page is a snapshot until then — see the READ ME tab for the original README in full.
The development and support of Librera is frozen for an unpredictable time, there is a big war in my country
Ukraine.

Librera Reader
Librera Reader is an e-book reader for Android devices;
it supports the following formats: PDF, EPUB, EPUB3, MOBI, DjVu, FB2, TXT, RTF, AZW, AZW3, HTML, CBZ, CBR, DOC, DOCX,
and OPDS Catalogs
You also need the Android NDK in version 20+
Please ensure to download it using android studio and add the NDK to your PATH.
Create a keystore
Even if you do not plan to upload a version yourself you need a keystore with a certificate to build.
The keystore needs to be in PKCS12 format.
You can create a keystore in your actual directory using the following call
(replace ALIAS by your alias, it is just a name):
Now edit or create the file ~/.gradle/gradle.properties and set following values
(replacing PASSWD by the password you typed while creating the keystore, ALIAS as before and using the path to your
keystore):
To build with firebase support (all version but the ones for Fdroid) you need to get an
authentication file for firebase services offered by google. Therefore please follow
https://firebase.google.com/docs/android/setup to create your own project. You need to
register for the packages com.foobnix.pdf.info and com.foobnix.pdf.reader.a1. This way
you will get a google-services.json file that you have to place in the app folder of
the repository.
For this project only Analytics is used, so a spakling plan is all you need.
Librera Build on MuPdf

./link_to_mupdf_x.x.x.sh (Change the paths to mupdf and jniLibs folders)
cd ..
./gradlew assembleLibrera
Building for F-Droid for Android
If you wish to build for F-Droid (e.g. not using google services, Internet) you can run the build with
cd Builder
./link_to_mupdf_x.x.x.sh
cd ..
./gradlew assembleFdroid
F-Droid build does also not need a google-services.json
