- follow the UX spec by no more using a Drawer - the Dashboard is now a Fragment that contains the list of Headers - the search results are also put into a Fragment that is replacing the initial one (Dashboard or other) when expanding the SearchView - use a SearchView for query input - when tapping on a Header or a Search Result, re-launch Settings as an Activity so that we are benefiting from the Activity stack for UP affordance and BACK button - manage UP affordance to show it only when needed - move some Actions to the Menu in the ActionBar for allowing space to the Search action and removing some clutter - fix an issue with the Index and WiFiEnabler and their cached Context that was not updated when there was a Configuration change - simplify the SettingsActivity code by extracting some inner classes Change-Id: I50b5f77bb44a7fade1886114dbbc820609a5e63d
