Android - Run/install/debug applications over WiFi

I was very tired to Install app through USB so I was wondering it would be cool if I can install apk over wifi and I found the solution:

1. Connect device via USB and make sure debugging is working.
2. adb tcpip 5555
3. adb connect <DEVICE_IP_ADDRESS>:5555
4. Disconnect USB and proceed with wireless debugging.
5. adb -s <DEVICE_IP_ADDRESS>:5555 usb to switch back when done.

No root required!

To find the IP address of the device: run ./adb shell and then netcfg. You'll see it there.
