Eclipse：“设备”视图中的未知设备

Question

在某些时候，尝试在模拟器上运行一个应用程序后我已经提前打开了，在启动时，它显示了这一点：

  

我只启动了一个模拟器，第二个。第一个带有警示标志的地方突然出现了。我甚至不拥有物理Android设备。

好的，我选择了正确的。之后决定检查设备视图，看起来像这样：

  

在任何地方都没有其他任何迹象可以找到（至少在我看来）。但它很烦人。任何人都可以弄清楚它来自哪里以及如何摆脱它？

更新：

现在我甚至无法在正在运行的模拟器上启动应用程序（从控制台登录），以下是错误日志：

另外：LogCat完全忽略正在运行的模拟器5556，但是，当我尝试“停止进程”时，那个带有问号的属于5554的那个，LogCat被所有人填满了各种各样的垃圾。

并且：当我尝试telnet到localhost 5554时，它通知我“无法打开与主机的连接，在端口5554上：连接失败”。我可以telnet到5556（当然，当它正在运行时）。

Answer 1

您是否已启动模拟器，将其关闭，然后启动第二个模拟器？如果是这样，第一个仿真器可能永远不会完全关闭。

您可以在Windows任务管理器中查看是否有多个模拟器实例

Answer 2

有些时候，当我启动环境时，我无法将我的应用程序从eclipse部署到我的Android设备。 然后，我运行此代码并正常工作：

adb kill-server
sudo adb start-server
