Java Commercetools Sphereio SphereClient为空

我正在尝试运行一个简单的示例来获取android中的产品详细信息，我使用java示例作为指南。

我得到一个错误：

io.sphere.client.SphereClientException: null: null

我的身材。格雷德尔：

是否有任何android示例可供我测试运行，以实现与Sphere的基本连接

commercetools平台有一个SDK，可用于所有JVM语言（“SPHERE JVM SDK”），但需要Java 8语言功能，因此无法在Android上使用，因为Android不是JVM

您正在尝试的“旧”SDK（不幸的是，它仍然在Java Hello World示例中使用）在技术上与Android兼容，但我不建议使用它，因为它不再维护（）

因此，到目前为止，Android客户端是使用Android内置HTTP客户端等直接针对HTTP API构建的。
实际答案：你可以在谷歌玻璃演示应用程序（GitHub，麻省理工学院许可证）中找到一个正常工作的Android示例： .

一个警告：SphereAPI的可用OAuth授权范围目前还不足以构建一个完全本地的应用程序，包括直接针对commercetools（SPHERE）API进行签出。你必须考虑要么不做结账（即WebVIEW），要么（最好）运行一个最小的服务器端API SIMM，它为公共应用程序白内容，做OAuthand知道秘密。

---

对于上面的Google Glass演示代码这样的原型/概念验证，这并不是一个问题。

与此同时，我们致力于更好地支持移动设备。 例如，我们为Android创建了Hello World，您可以将其用作移动应用程序的起点：

---

在不久的将来，我们将继续扩展对移动平台的支持。

您好，您能附上堆栈跟踪吗？thanks@sebbulonstacktrace补充道，客户端id和secret都是正确的，我可以肯定的是，有谷歌眼镜的样本并不奇怪，但仍然没有关注基本的android。正如您所说：SphereAPI目前还不足以构建一个完全本地的应用程序。大多数商店目前都把重点放在移动设备上。开发人员仍在努力以本地方式在移动设备上实现Sphere。Sphere未来的开发重点是什么？这有点不一致，这是正确的。但commerceools已将其列入路线图。您已经在反馈门户（）中创建了一个建议，可以在那里跟踪进度（此处不属于主题）。欢迎提供指向潜在解决方案的链接，但请务必提供，以便您的其他用户了解它是什么以及为什么存在。始终引用重要链接中最相关的部分，以防无法访问目标站点或永久脱机。考虑到仅仅是一个指向外部站点的链接是一个可能的原因。
