Google appinventor - what to do with barcode?

Question

Trying to create a hello world android app with app inventor, and there's an option to get the barcode. I got it, now, what the heck do I do with it? what's the point?

Thanks!

Answer 1

It's a QR code, which encodes the URL of the app you've just made. That way you can download and install it.

Answer 2

You can open a barcode reader app on an Android device and point the camera at the barcode on your screen. I use "Barcode Scanner" but there are other options too.
