问题描述

我只是目前继教程creaing Android应用（http://developer.android.com/training/basics/firstapp/building-ui.html）。我认为，香港专业教育学院遵循所有指令，但不能似乎能够运行按照其说明中提供的示例应用程序。下面是Eclipse提供的的反响：

任何想法？

推荐答案

您使用Eclipse？

Are you using Eclipse?.

你曾经能之前运行的程序？

Were you ever able to run the program before?

如果你可以再重新启动仿真器/电脑（先尝试重新启动你的模拟器）。
我曾经在一个蓝色的月亮，一旦得到这个错误，只有重新启动用于解决它的计算机。

If you could then restart your emulator/computer(try restarting your emulator first). I used to get this error once in a blue moon and only restarting the computer used to solve it.

我还没有想通了为什么它会发生。

I still haven't figured out why it happens.
