一、接入的准备工作
官方文档链接地址：开始使用一键登录和注册
按照步骤进行接入即可
二、项目参考（Unity项目）
注意：代码版本如果不适用新的Google API 请自行参考最新版本接口
SDKGoogleSignInActivity 主要用于登录的代码。UnityPlayer.UnitySendMessage的参数按照自己项目填写，com.xxxxx.my也是填写自己项目的路径。

}JsonToString 用于处理数据，将json数据转成string方便传输
java
package com.xxxxx.my;
import org.json.JSONObject;
public class JsonToString {
private JSONObject jsonObj;
public JsonToString()
{
jsonObj = new JSONObject();
};
public JsonToString AddJSONObject(String key, Object val) {
try {
jsonObj.put(key, val);
}catch(Exception e) {}
return this;
}
public String GetString()
{
String str = jsonObj.toString();
return str;
}
}
