如何解决真机不识别的问题

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调试等，发现没什么问题。

然后用命令： adb devices

结果发现设备是unauthorized.

网上搜了解决方案：

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。
