所以我一直在为一个项目开发这个应用程序，我的模拟器一直工作正常，直到今天早些时候，已经有 6 个小时左右的时间试图解决这个问题，但没有办法解决它。我已经删除了eclipse并重新安装了它，重新安装了android sdk，adt。一切，当我尝试运行我的 android 应用程序时，我一直收到相同的消息。

on top of that everytime I open the AVD on eclipse it wont let me create a virtual device, I have to go straight to the adt folder and open the AVD.exe.
最重要的是，每次我在 Eclipse 上打开 AVD 时，它都不会让我创建虚拟设备，我必须直接转到 adt 文件夹并打开 AVD.exe。
any way to fix this? is it the new android adt version 22.6? because it all happend after my eclipse did some updates. I also tried reverting the updates and it didnt work.
有任何解决这个问题的方法吗？是新的 android adt 版本 22.6 吗？因为这一切都发生在我的日食做了一些更新之后。我也尝试恢复更新，但没有奏效。

ADT version 22.6.3 java compiler 1.7 I had same problem. But I solved it. In my case
use same device for future launcheswas checked. which try to run on previous emulator. So
Go To Run Configuration->Target->uncheck use same device for future launchesif you want check Always prompt to pick deviceso that you get choice.
ADT 版本 22.6.3 java 编译器 1.7 我有同样的问题。但是我解决了。在我的情况下
use same device for future launches被检查。尝试在以前的模拟器上运行。所以，Run Configuration->Target->uncheck use same device for future launches如果你愿意check Always prompt to pick device，就去吧，这样你就有了选择。
here is console where both problem and solution is here
这是控制台，问题和解决方案都在这里

goto Run as-> run configure->target at the end find a tag "use the same device for future launches" remove the tick of check box. Again run application
goto Run as-> run configure->target 最后找到一个标签“使用相同的设备进行未来启动”删除复选框的勾号。再次运行应用程序
