1.前言

发布app到海外市场,内购不免要使用Google支付,然后发现集成Google支付有些流程和注意事项比起国内的支付宝、微信要复杂一些,在此记录一下.

2.准备工作

(1)请求的是国外的服务器,所有FQ工具是必须的.

(2)Google支付还要求手机安装Google三件套,如果没有安装,如下:

(3)准备开发者账号
Google开发者管理中心

(4)创建应用和提交测试版本(一般为Beta测试版),创建完后,要为应用添加商品,在添加测试人员账号,点击生成的链接即可,记录密匙

(5)初始化Helper的时候需要上面的密钥,根据同事反馈,密钥错误会报 response:-1003

3.Google支付大致流程

4.代码

//修改IabHelper的queryPurchases(Inventory,String)源码
