Since Preference.setIcon was only added in API 11, to add icons to preference in older Android versions you could clone the IconPreferenceScreen and then import to you project. You will need to make a few changes to load custom attributes.
After that you can just use the new IconPreferenceScreen in place of a Preference, and add an icon.
