The instruction tells me to change to "AppTheme" in the androidmanifest.xml do you know where exactly?

thats going to be on the bottom left hand side of your screen, double click that, then once you have that pulled up, look in the manifest.xml on the bottom where it shows applictaions, permissions, ect ect then androidmanifest.xml

I'm 99% sure you'll also want to click on the application section on the bottom the look in that area. Sorry Its been a while.

It's all good, I managed to get it to work after following the instructions! Thanks!
