Nexus7 doesn't do dual-pane thing on PreferenceActivity
I have been wondering why my PreferenceActivity doesn't become dual-pane(two-panes) mode, and I found it works fine on a tablet other than Nexus7. I confirmed getConfiguration().screenLayout is LARGE, so I wonder this is bug. Anyway my app is meant to work on tablet, so I finally do this  class PrefActivity extends PreferenceActivity() {     override def onIsMultiPane():Boolean = true }  However, this turns the preference activity into dual-pane on any device.  If anyone knows better solution, let me know...
