新入手了一台三星 S5.

装了驱动啥的。

用真机来跑 case.

结果在发现真机 offline.

再次检查了驱动,usb 调试勾选等,发现没什么问题。

然后用命令: adb devices

结果发现设备是 unauthorized.

上搜了解决方案:

adb kill-server

重插 usb

adb start-server

结果还是如此。

然后找谷歌帮忙,总算找到了一个解决方案:

I had similar situation. Here is what I did:

Try to check and uncheck the USB Debugging option in the device. (if not working, try to unplug/plug the USB)

At some point, the device should show up a messagebox to ask you if you authorize the computer. After you click yes, the device is then authorized and the connection is hooked.
照做,结果就起来了,设备终于 Online 了。
