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** ## Librera depends on: MuPDF - (AGPL License) https://mupdf.com/downloads/archive/ * ebookdroid * djvulibre * hpx * junrar * glide * libmobi * commons-compress * eventbus * greendao * jsoup * juniversalchardet * commons-compress * okhttp3 * okhttp-digest * okio * rtfparserkit * java-mammoth * zip4j Librera is distributed under the GPL ## License See the [LICENSE](LICENSE.txt) file for license rights and limitations (GPL v.3).
