Nit: Instead of the somewhat-redundant comment, how about just a better constant
name:

  const int kBubblePaddingFromScreenEdge = 20;

[Pritam Nikam, 2014/12/23 06:22:29]

Done.

+  const int kFullscreenPaddingEnd = 20;
+  int bubble_half_width = width() / 2;
+  const int x_pos = base::i18n::IsRTL() ?
+      (screen_bounds.x() + bubble_half_width + kFullscreenPaddingEnd) :
+      (screen_bounds.right() - bubble_half_width - kFullscreenPaddingEnd);
+  SetAnchorRect(gfx::Rect(x_pos, screen_bounds.y(), 0, 0));
+}
+
+void ManagedFullScreenBubbleDelegateView::Close() {
+  GetWidget()->Close();
+}
