首先 搭建环境的工作我不多说, 网上可以搜到一大堆;

然后 需要用到的请求还得读一读官方文档

unity代码部分经过简单的封装

unity 调androidSDK 首先需要 \_GetCurrentAndroidJavaObject() 得到AndroidJavaObj jo;

jo.Call<T>(apiName, args) 中 T代表返回类型, apiName 是SDK中的函数名， args则是对应函数的

unity c\#部分代码:

using UnityEngine;
    using System.Collections;
    using UnityEngine.UI;
    using System.Collections.Generic;
    using System;
    
    public class test : MonoBehaviour {
    
        private Text txt;
        string headimgurl;
    
        // Use this for initialization
        void Start () {
            GameObject btnObj = GameObject.Find("Canvas/Button");   //获取按钮脚本组件
             Button btn = (Button)btnObj.GetComponent<Button>();
            GameObject btnObj1 = GameObject.Find("Canvas/Button1");   //获取按钮脚本组件
            Button btn1 = (Button)btnObj1.GetComponent<Button>();
            GameObject btnObj2 = GameObject.Find("Canvas/Button2");   //获取按钮脚本组件
            Button btn2 = (Button)btnObj2.GetComponent<Button>();
            GameObject btnObj3 = GameObject.Find("Canvas/Button3");   //获取按钮脚本组件
            Button btn3 = (Button)btnObj3.GetComponent<Button>();
            GameObject btnObj4 = GameObject.Find("Canvas/Button4");   //获取按钮脚本组件
            Button btn4 = (Button)btnObj4.GetComponent<Button>();
            GameObject btnObj5 = GameObject.Find("Canvas/Button5");   //获取按钮脚本组件
            Button btn5 = (Button)btnObj5.GetComponent<Button>();
            GameObject btnObj6 = GameObject.Find("Canvas/Button6");   //获取按钮脚本组件
            Button btn6 = (Button)btnObj6.GetComponent<Button>();
            GameObject textObj = GameObject.Find("Canvas/Text");   //获取按钮脚本组件
            txt = (Text)textObj.GetComponent<Text>();
            //添加点击侦听
            btn.onClick.AddListener(onClick);
            btn1.onClick.AddListener(onClick1);
            btn2.onClick.AddListener(onClick2);

AndoridSDK调用unity c\#

UnityPlayer.UnitySendMessage("Canvas","json\_AcToken",a\_t\_r); Canvas是场景中的游戏对象, json\_AcToken表示游戏对象中某个脚本的函数名 ， a\_t\_r及之后的则是参数

值得一提的是 授权后需要的http请求, 还有json的解析, 既可以写在unity中也可以写在SDK中,

这里我图方便, 刚好unity中有json类, SDK中有http类, 所以我一个写在unity中 一个写在SDK中

当然这都不是正确的作法, 出于安全考虑 app\_secret,access\_token等信息不应该暴露在客户端中, 所以对应的http请求应该在服务器上进行。
