"No Android Device Found" on Build and Run

I have spent a solid six hours trying to build & run a very simple application onto an android tablet, connected by USB.

However the “No android device found!” message always assaults me before Unity can complete the operation.

I have enabled USB debugging, installed JDK, installed the correct SDK, and installed a device driver but with no luck. The error message tells me there will be a USB icon in the status bar of the device if the connection is up, and it is.

I am completely stumped. I’m using Unity 5, a Mac and an LG tablet.

I have enabled USB debugging, It’s worked on my project. Thanks btw.,“I have enabled USB debugging,” It’s worked on my project. Thanks btw :slight_smile:
