Just so you know, you can use your android phone.

Hey, so... if you plugin your android device with a USB2.0/3.0 Once it's plugged in you need to turn your phone on(If it's off)

Then turn on USB-Debugging How-to turn of USB-Debugging: Lollipop: Go to settings > about phone then tap on build number 7 times

Then go to developer, turn on developer options, and then turn on USB debugging

USB Debugging is under Debugging

Then close settings(Optional)

Then go into Android Studio, code your application. Once that's done you need to click RUN, then select your device(If it says something else then just do it, for an example my Huawei P8 Lite displays as a nexus (aNumber))

Have fun!

(This is NOT a question, I'm about to email to treehouse that they should add a tips/answers section where you could ANSWER questions instead of asking them. Ok, I know noone asked. But... here it is)
