第一应用版本选择一个版本

点击管理，创建版本

拖入一个Apk（可以打开一个新Unity项目，打包时这个Apk包要设置它的签名Player Settings=>Publishing Settings）让后填写其他内容，保存

商品详情，根据上面的要求将图片加入其中

选择游戏类型，保存

定价和分发范围，选择自己的应用付费或免费，向下填一些选择问题

在上传APK后要记得勾选上着三个按钮

上传完APK，在发布之前，游戏内的物品一定要设置

点击“应用内商品”

点击创建受管理的商品

点击添加价格

设置完后就可以发布了，点击应用版本=>点击项目上有修改版本=>点击右下角的查看=>发布发布完成后，在版本管理=>应用版本 点击管理测试人员有一个加入测试的网址 打开连接加入一下

到这Google后台基本设置好了

Unity设置

打开Unity点击Window=>Services 或Ctrl+0

Google后台密钥在 开发工具=> 服务与API

如果输入进去说格式不对或者无效先看看是不是有空格，还是不行的话

点击ALL Import

选择商品：

点击编辑脚本：

将代码全部替换

出现支付页面证明sdk接入成功

注意：如果有报错-1002，就是测试机的问题，在设置里面把Google商店和谷歌的所有产品的 允许应用弹出窗口 的权限打开，在测试就会出来支付窗口了

注意：如果内购无法购买并且报错没有初始化，但是初始化逻辑能走通，可能是测试机的google账号的问题，把测试机上的google账号全部移除，在重新登录就好了，就可以了

注意：测试机一定要，一定支持Google四件套
