Provide builds for other Android platforms

[vRallev]

Using your library with Android is pretty easy. Add the maven artifact as dependency and insert the precompiled ARM library. Using the native library is necessary, the computation is about 20 times faster on my Nexus 5, because of the slow garbage collector in the pure Java implementation.

I tried to build the library, but I failed. Could you also provide a precompiled version for x86 and MIPS platforms?

I think it would be nice if there was a second artifact – maybe named "scrypt-android" – that included all the usual .so for the different Android platforms and had a dependency to the already existing "scrypt" artifact.
