Lincoln's updated building instructions

On an Ubuntu machine, run

• ./install_software.sh
• sudo update-alternatives --config java and choose jdk 8
• ./download_ndk.sh
• ./build_android_libsodium.sh
• cd jni && ./install_swig.sh (runs a sudo make install, fyi)
• ./build_jni.sh

This should output into libs a bunch of .so files. You need to copy them into the monorepo as such, as well as the SodiumJNI file:

• export MONOREPO=~/w/monorepo (edit this path)
• cp -r libs/* $MONOREPO/android/lib/src/main/jniLibs/
• cp src/main/java/org/abstractj/kalium/SodiumJNI.java $MONOREPO/android/lib/src/main/java/org/abstractj/kalium/

What I did to bring this into Wave's codebase was to vendor all the Java files, but pre-compile the native library on my machine, because I didn't want to do an ndk build process for our whole team.

To change the functions exported to the JNI, edit jni/sodium.i.

Below is the original readme.

Robosodium

Robosodium was born as a fork of kalium-jni. With this library you will be able to compile libsodium for Android platforms and automatically create the wrapper for the JNI.

How to

1. First of all download this repository and its submodules:

$ git clone https://github.com/GerardSoleCa/Robosodium
$ git submodule init 
$ git submodule update

2. Start from first clone:

$ ./do_the_job.sh

3. Build JNI for Linux instead of Android:

$ ./do_the_job.sh linux

4. Where to find the compiled libs:

cd libs # Libs for Android using the architecture dirs
cd linux_lib # Lib for Linux. To be used copy to /usr/lib for example. Or just place anywhere you want

5. If something goes wrong or you want to run again some parts of the compilation, just call the following scripts:

do_the_job.sh # Start and run all the scripts
install_software.sh # First update aptitude cache and install necessary packages
build_jni_linux.sh # Build libsodium with jni for linux.
download_ndk.sh # Download the required Android NDK
build_android_libsodium.sh # Compile Libsodium for Android
build_jni.sh # Generate the JNI library (*.so)

Build AAR

On Linux, simply run:

$ ./build_aar

On OS X, ensure that you have SWIG, Android SDK and NDK installed, and your JAVA_HOME, ANDROID_HOME, ANDROID_NDK_HOME set, then run:

$ ./build_aar_osx
