Question

我在我的应用中使用Google Play结算库。内部测试发布类型中的应用发布。但是，当我单击产品按钮时，launchBillingFlow（）无法显示Google Play购买屏幕。单击后，代码直接跟随该块的“ //执行某些操作并返回菜单操作”部分。我的应用程序配置行：首先在清单中有一个“ com.android.vending.BILLING”。其次;我的gradle文件具有当前版本的计费库； “实施'com.android.billingclient：billing：2.0.3'”。但是我不知道为什么仍然无法显示购买屏幕。我的代码如下；

    }
}

为什么在解析调用querySkuDetailsAsync的结果时开始购买？您应该在按钮的onClick事件或由用户的操作触发的事件中包含一个按钮和launchBillingFlow。

在querySkuDetailsAsync的回调中，您可以解析结果并获取一些SKU元数据来呈现您的付费专区。

launchBillingFlow（）无法显示Google Play购买屏幕
