com.android.ddmlib.AdbCommandRejectedException:设备离线(即使设备已连接) [英] com.android.ddmlib.AdbCommandRejectedException: device offline (Even when device is connected)

问题描述

将 Android Studio 更新到 2.1.2 后，我在进行更改时多次收到以下错误.

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过且未离线

如果我拔下并重新插入设备，它会再次开始正常工作.这在以前版本的 AS 中从未发生过.

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

问题:是否有需要在 AS 中更改设置以阻止这种情况发生，或者这是一个错误?

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

推荐答案

使您的 Studio 缓存无效，重新启动您的设备，PC 将工作.有时候端口也有问题，你也换个电脑的usb端口试试.

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.
