我是 Android 的初学者。我做了几个小项目来学习android。但是当我再次尝试做一个早期的项目时，模拟器显示应用程序失败。我尝试了bluestacks，但还是一样。当我尝试运行之前已经安装在模拟器中的一些应用程序时，我发现，以前运行的这些应用程序现在都没有运行。我尝试调试其中一个以前可以运行的应用程序，但没有对代码进行任何更改，得到的 logcat 输出如下（抱歉粘贴了整个内容，但我实际上无法弄清楚实际问题）：

我尝试用谷歌搜索CPU may be pegged错误，但没有得到实际答案。相反，他们都在谈论一些使用音频的高级应用程序中的相同错误，但我尝试调试的程序是一个简单的 Hello World 应用程序。在某个地方有人告诉关闭并重新打开eclipse和模拟器，重新启动系统，我尝试了一切，仍然没有运气。在过去的几天里，我一直坚持这一点。在 logcat 中搜索所有可能性，但没有得到任何答案。如果有人知道可能是什么问题，请提供帮助。
如果这有用，这是调试器屏幕的屏幕截图。
