Unity Remote (Android)

I formatted my computer yesterday. When I test my project in Unity to Android 4.0, it stopped making the remote connection by USB.


I followed all the steps:

I installed the latest SDK and have configured Unity and Tablet.
Restarted the computer.
I started the Application (Tablet with USB debugging).
I started and I tested Unity Project.

Please can someone tell me what may be happening is this problem?

I had this problem the other day
MAke sure you have the correct SDK installed, I had to download a package in the SDK manager because I was on a laptop, the SDK wasI had was for desktop
Perhaps thats the issue, check out to see if you have all your platforms and packages installed

Im on a mac, if you are on a windows machine I cannot help any further lol
