Android UI guidelines http://developer.android.com/design/downloads/index.html provide a back button image download but the button appears to be a bit different from the one used in the action bar. The stencil for the action bar "back/up" is not available in the Android stencils. Does anyone know if there is standard "back/up" button resource or each app is responsible for creating it's own (opens door for less consistency)? Or does the back button comes automatically with action bar?
