Create a new Android Studio project with an empty view.

Create a folder in the root project folder called "jni"

EXCLUDING sanity.c and bench.c Drag and drop all the .c and .h files from NTRUMLS-Master /src directory into the jni folder.

Create a file called Android.mk in the jni folder with the following contents

LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)

LOCAL_ARM_MODE := arm


LOCAL_MODULE := libntrumls
LOCAL_CFLAGS := -Werror
LOCAL_SRC_FILES := crypto_hash_sha512.c \
                    crypto_stream.c \
                    convert.c \
                    randombytes.c \
                    fastrandombytes.c \
                    pack.c \
                    pol.c \
                    params.c \
                    pqntrusign.c \
                    shred.c

LOCAL_LDLIBS := -llog

include $(BUILD_SHARED_LIBRARY)

than run ndk-build in the project root folder.
