To test, open a virtual phone in your Android Studio Device Manager or, to test on a physical device,
you will need to enable developer options on your phone. To do so, go into settings, About Phone,
locate your Build Number, and tap it 7 times, or until it says "You are now a Developer". Then,
go back to the main Settings screen and scroll once again to the bottom. Select Developer options
and enable USB Debugging.
Then plug your phone into your computer and hit the green play button at the top of
Android Studio. It will load for a moment before prompting you to select which device to install
it on. Select your device from the list, and hit continue.
NOTE
