How to add this library as a dependency in an Android project

Hey @AkritiSondhi, thanks for showing interest in this library.

As is the case with Swift, I am not very at all experienced with Android development. I made the JNI bindings as is, and have only tested them on my phone. I'm already sorry for the bad support, but I will try my best.

I have not put the library on any package manager (just because I do not yet know how the Android build system seems to work). I would recommend using JitPack instead. They provide an example at https://jitpack.io/docs/. Translating this to sss-android should probably give something like:

    allprojects {
        repositories {
            jcenter()
            maven { url "https://jitpack.io" }
        }
   }
   dependencies {
        compile 'com.github.dsprenkels:sss-android:master-SNAPSHOT'
   }

Note that to compile native code you additionally need the CMake, LLDB and NDK tools. On Arch Linux, you will probably run into this problem which can be solved by installing ncurses5-compat-libs from the AUR.

This will maybe not solve everything, but should probably get you started. Please, if you can spare the effort, tell me if it works properly. Then I can write a proper README.md file in the sss-android repo. Thanks in advance!

It may be of help, as a hint or alternative solution, to have a look at what we do with Zenroom which uses this library as entropy generator (seed) for a cryptographically secure RNG. Here are the build instructions also pointing to scripts https://github.com/DECODEproject/zenroom/wiki/Build. Beware that including Zenroom may be overhead (~1MB payload) if only randombytes is really needed.

Closing as a stale issue.
