运行时没有命令输出:'am start -n

Question

最近,当我试图在我的设备上运行我的Android应用程序时,我必须在实际启动之前从Eclipse运行它几次.

我试图重新安装JRE,JDK和IDE,我试图切换工作区.我还让Eclipse为Java VM使用更多的RAM.

我的IDE,JRE,JDK,ADT和ADT插件都是最新的.

对此有任何建议非常感谢.

运行时没有命令输出:'am start -n com.example.abstab/com.example.abstab.ActivityMain -a android.intent.action.MAIN -c android.intent.category.LAUNCHER'​​on device HT15CV805781

我大多数时候都会遇到同样的情况，当我重新启动ADB服务器时它就会起作用。大多数时候，ADB 会陷入某种困境（特别是当模拟器重新启动时），我不得不手动重新启动它，如下所示：

adb kill-server
adb start

使用上述命令重新启动ADB后，Eclipse Android运行非常稳定。
