initial activity views

Couple of things:

1) Switch is only available in API level 14 or above. So I set the minimal API level to 14
2) By default ActionBar has black background and white font, and I didn't see a way to set ActionBar attributes statically. So I had it in the java code. I am not sure if it's the right thing to do.
3) I don't know how to set style of switch and spinner to make it look more like the wireframe..
4) We may need to pick / draw a better icon.
