com.android.ddmlib.AdbCommandRejectedException:设备脱机(即使连接了设备) [英] com.android.ddmlib.AdbCommandRejectedException: device offline (Even when device is connected)

问题描述

在将Android Studio更新到2.1.2之后，进行更改时，出现了很多次以下错误.

After update of Android Studio to 2.1.2 I've been getting the following error too many times when i make a change.

com.android.ddmlib.AdbCommandRejectedException:设备离线

com.android.ddmlib.AdbCommandRejectedException: device offline

安装APK时出错

问题是设备从未连接且未离线

如果我拔出并重新插入设备，它将再次开始正常工作.在以前的AS版本中从未发生过这种情况.

If i unplug and re-plug the device it starts working fine again. This never happened in the previous version of AS.

问题:是否需要在AS中更改设置以使其停止发生或者是错误?

Question: Is there a setting to be changed in AS for this to stop happening or it is a bug?

推荐答案

使Studio缓存无效，重新启动设备，PC即可工作.有时端口也有问题，只需在更改PC的USB端口后再尝试.

Invalidate your Studio cache, restart your device and pc will work. Sometimes the problem with port also, just try after changing the usb port of your pc also.
