我想添加对安卓源代码的Node.js支持

node -v
npm -v

#include <node.h>

namespace demo {
  using v8::FunctionCallbackInfo;
  using v8::Isolate;
  using v8::Local;
  using v8::NewStringType;
  using v8::Object;
  using v8::String;
  using v8::Value;

  void Method(const FunctionCallbackInfo<Value>& args) {
    Isolate* isolate = args.GetIsolate();
    args.GetReturnValue().Set(String::NewFromUtf8(isolate, "world", NewStringType::kNormal).ToLocalChecked());
  }

  void Initialize(Local<Object> exports) {
    NODE_SET_METHOD(exports, "hello", Method);
  }

  NODE_MODULE(NODE_GYP_MODULE_NAME, Initialize)
}

npm install -g node-gyp

mkdir build
cd build
node-gyp configure

{
  "targets": [
    {
      "target_name": "addon",
      "sources": [ "hello.cc" ],
      "include_dirs": [
        "<!(node -e \"require('nan')\")",
        "/path/to/android-ndk/sysroot/usr/include"
      ],
      "libraries": [
        "-L/path/to/android-ndk/platforms/android-21/arch-arm64/usr/lib",
        "-llog"
      ],
      "cflags": [
        "-std=c++11"
      ],
      "cflags_cc": [
        "-std=c++11"
      ]
    }
  ]
}

node-gyp build

static {
    System.loadLibrary("addon");
}

const addon = require('./build/Release/addon.node');
console.log(addon.hello()); // 输出: world
