STEP-BY-STEP GUIDE HERE:
ON YOUR ANDROID
1. Goto "Settings" then "About Phone".
2. Tap on "Build Number" until you get a message saying you're a developer.
3. Go back to "Settings" and open the "Developer" tab.
4. Go down to where it says "Android Debugging" and make sure its on (VERY IMPORTANT).
5. Goto Google Play and download "Unity Remote 4" (MAKE SURE ITS 4).
ON YOUR COMPUTER

7. Extract all the files and open Android Studio

11. Continue and click "Accept", then "Finish" and wait for the SDK to install.
IN UNITY 3D
12. Goto "Preferences", then "External Tools" and make sure "Android SDK Location" is set to the folder Android Studio installed.
13. Goto "Edit", then "Project Settings" and click on "Editor".
14. On the right panel of your screen, make sure "Device" is set to "Any Android Device".
15. Once all that's done, open Unity Remote on your Android (DONT PLUG IN YET).
