如果我这样运行这个脚本，它就能正常工作。

但是如果我加了一些延迟（比如time.sleep(10)），那么就会出现这个错误。

Answer 1

这个错误发生在等待连接超时的时候。

虽然说明书上说默认是永远等待，但我发现如果把超时时间设置得更长，并且加上设备的ID，似乎就能解决这个问题。

比如可以这样写：MonkeyRunner.waitForConnection(1000,"emulator-5554")

Answer 2

我想这可能是我使用的CyanogenMod系统出了问题。在我给手机安装了新的操作系统后，一切都正常。所以问题不在于脚本，而是我的CyanogenMod系统有点不稳定。
