If you are just starting out building applications from Unity, we suggest starting out with the Android process. The workflow for getting your project export from Unity to playing on your device is short and straight forward:
- On your Android device, navigate to Settings | About phone or Settings | About Device | Software Info.
- Scroll down to Build number and tap the item seven times. A popup will appear, confirming that you are now a developer.
- Now navigate to Settings | Developer options | Debugging and enable USB debugging.
