[ANDROID] Where is this app getting the UUID?

[BlueMustache]

Hey Guys,
I am reverse engineering the api for a really chintzy phone company in America.
It's called Tracfone. They charge your through the nose for their services, and on top of that, their customer service sucks.
They are kind enough to provide an app that will show you your balance of "minutes" and texts, but when you use the app or website which is the only way.
It shows the balance to you free of charge, except they sneak in sending a text message to your phone, stating your balance, so they steal a text message.
I have reverse engineered the app, into letting me find the XML of my phone's balance. The problem is, I want this to work for other people too, which requires in
MMTracfoneUtils.java at line 278 for a UUID. I found my uuid, but I want to know how it is generated, or where it can be found. I have tried everything, packet capturing, decompiling, and still I don't know how it gets that string. All I know is that it stores it in the default application preferences.
I also know that it HAS to be a calculate number, somehow relating to the MEID DEC, since that's what they use for the website. And no, thta's not it. My uuid doesn't match it.
I hope ya'll can help me out.

Thanks!

P.S. With the Galaxy 6S coming to Tracfone, I don't want people getting screwed on their minutes.
