Java sample code

At first, call once

System.loadLibrary("gnustl_shared");
System.loadLibrary("gmp");
System.loadLibrary("gmpxx");
System.loadLibrary("mcl_bn256");

and use Bn256.* functions. See JNI for mcl.

BLSsignature() in MainActivity.java is a BLS signature sample.

C++ sample

At first, call once

System.loadLibrary("gnustl_shared");
System.loadLibrary("gmp");
System.loadLibrary("gmpxx");
System.loadLibrary("mcladt");

bn256_sample() in jni/mcl/mcladt.cpp is a pairing sample.
