            @Override
            public boolean onTouchEvent(final MotionEvent event) {
                //note: all touch events that occur here are outside the dialog, yet their type is just touching-down
                boolean shouldAvoidDismissing = ... ;
                if (shouldAvoidDismissing) 
                    return true;
                return super.onTouchEvent(event);
            }

            @Override
            public void onBackPressed() {
                boolean shouldAvoidDismissing = ... ;
                if (!shouldSwitchToInviteMode)
                    dismiss();
                else
                    ...
            }
        };
