Question

我正在用Eclipse构建一个Android应用程序，直到我添加了一个特定的KeyEvent代码，一切顺利。一旦我试图模仿我的应用程序，它就崩溃了并且死了。我试图多次清理它，但它没有得到解决。此外，当我尝试编辑源路径时，源会显示一瞬间但消失。以下是未找到的来源：

ActivityThread.performLaunchActivity(ActivityThread$ActivityClientRecord, Intent) line: 2159    
ActivityThread.handleLaunchActivity(ActivityThread$ActivityClientRecord, Intent) line: 2189 
ActivityThread.access$600(ActivityThread, ActivityThread$ActivityClientRecord, Intent) line: 139    
ActivityThread$H.handleMessage(Message) line: 1261  
ActivityThread.main(String[]) line: 4894    
ZygoteInit$MethodAndArgsCaller.run() line: 784  
ZygoteInit.main(String[]) line: 551 
NativeStart.main(String[]) line: not available [native method]

如何让它们变得可以使用？我非常接近我的应用程序准备好了。这是我的应用程序中唯一的挫折。

编辑：这是logcat输出：
