I tried "xWalkView.setBackgroundColor(Color.BLUE);" with latest crosswalk, it works. BTW, we didn't use android::background in the layout file to set this color. I just raise this as a feature: https://crosswalk-project.org/jira/browse/XWALK-4628.
Here are some hints about background color: 1), Some page has its own background. If open www.intel.com<http://www.intel.com>, you will see the color set by setBackgroundColor a fraction of second. But soon this will be covered by the whole page. If open http://www.baidu.com/, I can see the BLUE even when page loaded. 2), white screen flick If add "XWalkPreferences.setValue(XWalkPreferences.ANIMATABLE_XWALK_VIEW, true);" there will be a white screen flick when you switch from background to front. If add "XWalkPreferences.setValue(XWalkPreferences.ANIMATABLE_XWALK_VIEW, false);" (this is the default setting for latest crosswalk) , no white screen observed.

Date: Thu, 16 Jul 2015 00:28:43 +0000 Hi, which crosswalk are you using? As I know, this is a fixed issue. For canary version, it is fixed since 2015.feb,9. For crosswalk 12, since 2015.feb,23. You can check it here: https://crosswalk-project.org/jira/browse/XWALK-1910.

Dear Crosswalk team, I would like to customize the background color of the XWalkView, however, this seems impossible / non-functional via the setBackgroundColor() API or via XML Please see below for my implementation details... As you can see, I would like to have the background set to Blue, however, it always shows as white. Screenshot is attached. What do I need to do to be able to set the background color of the XWalkView ? My Goal is to absolutely avoid the initial white screen, even for a split second. Once the HTML loads the background color no longer matters.
