Probably you added the reference to the Java project in the "Java Build Path" but it's the wrong place. 您可能在“Java Build Path”中添加了对Java项目的引用，但这是错误的地方。

From the Android guide: 来自Android指南：

To add a reference to a library project, follow these steps: 要添加对库项目的引用，请按照下列步骤操作：

In the Package Explorer, right-click the dependent project and select Properties. 在包资源管理器中，右键单击依赖项目，然后选择“属性”。
In the Properties window, select the "Android" properties group at left and locate the Library properties at right. 在“属性”窗口中，选择左侧的“Android”属性组，然后在右侧找到“库”属性。
Click Add to open the Project Selection dialog. 单击“添加”以打开“项目选择”对话框
From the list of available library projects, select a project and click OK. 从可用库项目列表中，选择一个项目，然后单击“确定”。
When the dialog closes, click Apply in the Properties window. 关闭对话框后，单击“属性”窗口中的“应用”。
Click OK to close the Properties window 单击“确定”关闭“属性”窗口

This resolved my problem. 这解决了我的问题。

In my case helped, not to have in the referenced projects checked Is Library 在我的情况下帮助，没有在引用的项目中检查Is Library

(Project Properties > Android) （项目属性> Android）

未选中“Is Library”的示例图像

I am also having issues with this error and have noted that if I run eclipse as root then the error disappears. 我也遇到了这个错误的问题，并注意到如果我以root身份运行eclipse，那么错误就会消失。 This makes me think it is a permissions issue 这让我觉得这是一个权限问题

So to help: 所以帮助：

On the com Facebook android project right click > android tool > build and export 在Facebook Facebook项目右键单击> android工具>构建和导出

Then simply build the project into the bin folder of the Facebook project. 然后只需将项目构建到Facebook项目的bin文件夹中。
