DropboxUnlinkedException安卓

Question

我在dropbox网站上学习这个教程。

用于android dropbox的图层

我已经获得了应用程序的密钥和秘密，并将它们放在我的代码中，并在清单中的正确位置。此外，舱单也有互联网许可。

所以布景没问题。该应用程序的目的是上传一个文本文件到我的dropbox帐户。它似乎开始正确地进行身份验证，但是putFile()方法正在抛出一个DropboxUnlinkedException。当应用程序运行时，您必须允许访问您在电话上的帐户，当我单击“允许”应用程序完成正确的身份验证时。我认为，除了执行putfile()方法之外，一切都很好。

我试过在应用程序开始时清除键，但仍然没有运气。

我做了一些日志，但不知道现在该做什么，有什么想法吗？

谢谢马特。

Answer 1

我已经解决了这个问题。

由于你还没有在这里贴出答案，我想这个问题对你仍然是开放的。

遵循以下步骤：(我只会提到我所遵循的额外步骤)

1. 去项目的财产。
2. 转到Java构建路径
3. 订购和出口
4. 选择json_simple-1.1.jar (将出现右复选标记)
5. 现在选择json_simple-1.1.jar和dropbox-android-sdk jar，然后按下右边的向上按钮，将它们移动UP。
6. 清洁，建立你的项目。

它已经完成了:)
