支付宝沙箱集成无法唤起客户端

支付宝沙箱集成

我当时是无法唤起支付宝客户端支付界面，显示服务端订单错误 ALIN10146

这里我是将官方demo复制然后进行更改的，这是需要留下的类

这是主页面代码

/**

     //这个需要换成自己的ID
    public static final String APPID = "2021000118612472";
    //换成对应的私钥

我天真的以为这样就完了，结果onCreate没有添加这句话

//打开沙箱环境
EnvUtils.setEnv(EnvUtils.EnvEnum.SANDBOX);

加上之后终于成功了，记录一下，引以为戒
