在去这里：在我的项目上单击右键>属性>安卓以下错误发生

When going here: right-click on my project > Properties > Android the below error happens.

当我转到属性>安卓上的项目或任一库（忽略BibleTriviaPro）这个错误发生。

This error happens when I go to Properties > Android on the project or either of the libraries (ignore BibleTriviaPro).

此错误似乎已不知从哪里冒出。我想不出什么我已经改变了，现在突然今晚的这个错误出现。我该如何解决这个问题？

This error seems to have came out of nowhere. I cannot think of anything I have changed and now all of a sudden tonight this error comes up. How can I fix this?

推荐答案

我有同样的错误今天早上奇怪，因为一切都很好，昨晚。

I was having the same error this morning strange as everything was fine last night.
