nit: unused

[Jaekyun Seok (inactive), 2014/12/02 03:13:13]

DCHECK requires this.

+#include "content/public/browser/android/ui_resource_provider.h"
+
+namespace ui {
+
+scoped_ptr<UIResourceAndroid> UIResourceAndroid::CreateFromJavaBitmap(
+    content::UIResourceProvider* provider,
+    jobject bitmap_object) {
+  if (!bitmap_object)

Why do we need to handle this? Should it be DCHECK()? Or should it at least
return null?

This method isn't used at all. I will remove it.
