Android app gets device ID and saves into Variable

Question

My app needs to do the following thing, right when I turn it on it reads the devices ID (the unique ID each device has) and then saves that into a Variable. I can do the saving no problem.

I was hoping any of you know how to do that? I can't seem to find info on how to extract this ID from the device. I need my app to run on a non-root device too

where do I put this? Can I call this from my MainActivity? and get any of those 3 variables. Thank you :) – KP Nany Jun 20 '16 at 22:08
They are fields in the android.os.Build class. You can import that class and then use them directly or equate them to Strings. – usajnf Jun 20 '16 at 22:12

Keep in mind that Device ID's can theoretically be changed if the user flashes a new ROM. There's no ID that I'm aware of (though Google may have recently added one, I'm not sure) that lets you know with 100% certainty that you're always on a specific device.
