编辑:

当我将 android.test.purchased 用作 SKU 时，它可以正常工作，并且当我用 更改 sku 时product_id 然后它给我 Error Authentication is required。您需要登录您的 Google 帐户。

最佳答案

请确保您在 Playstore 中用于应用内购买的产品 ID 是“test_product”，您应该在代码中使用相同的 sku。如果您从应用程序中更改 sku，则所有可能的 sku 名称必须作为应用内产品存在于 PlayStore 中。我曾经遇到过这个问题，原因是我的 SKU 项目在 Google Playstore 应用内产品中不存在，我只是将它添加到 Playstore 并解决了。

关于Android 应用内购买 V3 错误 : Authentication is required，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/29814460/
