Hmmm could you make a screenshot of what you see? I think I may've been wrong -
there's still too much padding being applied.

We have two SDK versions we need to verify: 21 (L) and 17 (JB). It might well be
that the needed padding differs for them :/.

Change the padding to 0, 0, 8, 0. Only leave the padding on the right side of
the button.

             return;
         }
         bigView.setOnClickPendingIntent(R.id.origin, mSettingsAction.intent);
