With single header file json.hpp
Source Code:

#include <stdlib.h>
#include <stdio.h>
#include <iostream>
#include "json.hpp"
using namespace std;
using json = nlohmann::json;

int main()
{
    json j;
    j["pi"] = 3.141;
    j["hello"] = "world";
    std::cout << j << std::endl;
    return 0;
}

Android.mk:

LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := test
LOCAL_C_INCLUDES := $(NDK_MODULE_PATH)/include
LOCAL_SRC_FILES := test.cpp
include $(BUILD_EXECUTABLE)

Application.mk:

APP_ABI := armeabi-v7a
APP_PLATFORM := android-21

APP_CPPFLAGS += -frtti -fexceptions -std=c++11

The assertion seems to be outside of the library.

That is a compiler crash (ICE) and there is nothing we can do to prevent that. Looks like maybe Microsoft already fixed it:
