[android] How to test android apps in a real device with Android Studio?

I have a Nexus 4 and own a Thinkpad L430 Windows 8.1

My errors: "Waiting for device. USB device not found"

I went to: Device Manager > View > Drop to "Acer Device" > Right click on Acer Composite ADB Interface > Update it

Afterward, Reboot/Restart your computer. Once it turned on Plug Your USB Device onto the computer.

Go to: Setting > Enable "Developer options" > Check the "USB debugging" option > Check "Allow mock locations" > Check "Verify apps over USB".

Swipe down from the drop down menu of your phone where it Shows the USB Connection Icon. Tap on USB Computer Connection > Select the Check box "Camera (PTP)"

Run your Android Studio App and it should work
