This code fragment asks for a connection to port 12580 on the device
itself. So you are asking the Android device to connect to a socket on the
same Android device. Is that what you intended?
//While on the Simulator use "10.0.2.2" it works!!!
You don't show code or describe your configuration, so I'm not clear on
what you mean by "works". But generally you don't have a network
connection between the device and your PC. It takes something called
"reverse tethering" via USB. The emulator runs on the same network as its
host, which is why you had no trouble there.
When Googling the terminology myself just now, I came across this
badly-written but potentially useful little article:

There are problems with reverse tethering; tread carefully.
So you have two problems. You're trying to connect the Android device to
itself, and you have no network connection from the device to the PC.
