Can not Run my Application on Samsung Galaxy S5

First of all I must say that I have been working around this issue for two whole days and I can not solve it. I googled it, I read this article from Donandroid, this thread from SO and many other reviews.

I have installed Samsung Kies3, Android sdk for windows, google_usb_driver on my windows 7 64-bit system. I also check the USB Debugging option in my Galaxy S5 and restart my phone. I also have restarted the ADT

Now when I check the attached devices in adb, I get:

$adb devices
$List of devices attached
4d0005444cc34139    unauthorized

I have tried to run my application on this device, but I have got this in ADT: enter image description here

I have no idea what to do now. I am totally frustrated. Any help would be greatly appreciated guys.

Solution

Ok, solve the problem. I have unplugged/plunged the usb cable for 3 times and suddenly the popup authorization message showed up on my phone. I allowed that and now everything is fine. I can not believe I spent two days in this issue. Hope this thread will help someone.
