我在使用Android SDK基于Eclipse，构建工具19.0.2，在Windows 7 PC上开始一个新的Andr​​oid应用程序。在我的工作中的一些问题，我开始收到错误找不到API库;未执行API检查。这个错误是不是在code显示，而是显示一个红色的X在项目文件夹，并在问题窗口中的行一个错误。有关于这个主题的previous问题，但是这并没有为我工作。我已经尝试调整目标和最低的SDK版本在清单中，重新安装了SDK多次。此问题也发生在我的工作空间中的唯一项目，并给出了同样的错误。在此先感谢您的帮助。

I'm starting a new Android App using the Android SDK on Eclipse, build tools 19.0.2, on a Windows 7 PC. At some point during my work, I started receiving the error "Can't find API database; API check was not performed". This error is not shown in the code but instead shows a red X in the project folder and a line one error in the Problems window. There is a previous question on this topic but that did not work for me. I have already tried adjusting the target and minimum SDK versions in the manifest and re-installed the SDK multiple times. This problem also occurs with the only other project in my work space and shows the same error. Thanks in advance for any help.
