Required build libs

mesa-common-dev libxcursor-dev libxrandr-dev libxinerama-dev libglu1-mesa-dev libxi-dev pkg-config libgl-dev

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):

keytool -genkey -v -storetype PKCS12 -keystore keystore.pkcs12 -alias ALIAS -keyalg RSA -keysize 2048 -validity 10000

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):

RELEASE_STORE_FILE=/PATH/TO/YOUR/keystore.pkcs12
RELEASE_STORE_PASSWORD=PASSWD
RELEASE_KEY_PASSWORD=PASSWD
RELEASE_KEY_ALIAS=ALIAS

Create Firebase Authentication file

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

cd Builder
./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
