So you should add this tag into manifest like .. <application android:logo="@drawable/custom_image" Update : You can use ActionBar.setLogo() for runtime. Two versions are there

问题 I'm working on an App utilizing ActionBarSherlock with navigation tabs and multiple fragments. I have three navigation tabs each with one or more child views. I also have three option menu items with one or more child views. Everything works fine when I drill down the views within each Tab or option menu.

问题 I'm using ActionBarSherlock to make my app compatible with older devices. The implementation was easy, but now i need to style the default Holo blue line that you see under the tabs to a red line.
