view story

http://stackoverflow.com – I searched a lot and I couldn't find any useful post. When I open my application (application use sherlock fragment ) shows black screen,application name with blue line in header and after 2 seconds appears splash screen. What should I do for passing this.. So when I press application button it show directly splash screen. here is my style that I use <style name="Theme.MyTheme" parent="@style/Theme.Sherlock"> <item name="android:actionBarItemBackground">@drawable/trans</item> <item name="android:buttonStyle">@style/ButtonMyTheme</item> (HowTos)
