推荐答案
试着改变ADB连接超时。我认为它的默认值，为5000毫秒，我改变了我的给10000ms摆脱这一问题的。如果你是在Eclipse中，你可以经过窗口做到这一点 - > preferences，然后它在DDMS Android的下
Try changing the ADB connection timeout. I think it defaults that to 5000ms and I changed mine to 10000ms to get rid of that problem. If you are in Eclipse, you can do this by going through Window -> Preferences and then it is in DDMS under Android.
