Add minSdkVersion to manifest file, fixes weird layout problem

Using a Samsung Note 10.1 2014 edition (tablet) in landscape mode, this happens: http://i.imgur.com/j1QJWneh.png
After adding minSdkVersion: http://i.imgur.com/7pN5o6kh.png
Keep in mind that it's a 10.1" display, so that logo was HUGE and you could not scroll down or otherwise access the buttons below.

SDK version 4 is the lowest version that still works properly. Using later versions (15+ or so) gives the app a different look (blue-ish buttons and added Action Bar), but no difference otherwise.
