The old design of my first app was simple. But there is not a lot of space for map. And the map is most important visual thing for my app. For that reason i need to use map full screen with more smaller and good looking buttons. I decide to to use Sherlock Action Bar. It looks simple and work every android version with same UI. First thing i want is using split action bar. I want to put all of my button into action bar. While i get some space for map, my app provides a good android 4.0 exprience on every single android version. https://play.google.com/store/apps/details?id=com.kozaxinan.locator If you find my blog or apps usefull, please consider donation.
