Can't get Unity remote running

I installed the SDK the JDK, specified their paths in unity.
I went to edit ->editor and selected any Android device.
I installed unity remote5 and checked the Usb debugging option.
Yet when I click play nothing happens on the phone( I know it’s connected to my pc because i can access the files of the phone) I would really appreciate if anyone helped because I am extremely frustrated right now and am banging my head against the wall.
