Q:

Android WebView: parallel Loading, Layout and Javascript

I have many (5-10) WebViews that are shown simultaneously (e.g. as a "carousel" similar to stock Gallery).  Remote web sites are loaded into these WebViews (not local html files).  The web sites are quite complex - they have lots of javascript, images, may have some flash...
When app starts, all WebViews start loading/layouting their content and running javascript - all this takes quite some time.  On the other hand, app is very responsive when the WebViews are loading - scrolling and other UI stuff is really smooth - CPU is definitely not under pressure. 

So is it possible to make those views load in parallel?  I think my app will benefit greatly from loading WebViews in parallel. 
Also, maybe there is a way to do javascript, load and layout manually by reusing WebView source code?

Answering my own question:

Is impossible - javascript on all webviews (and consequently layouting) is done on the same shared thread. 
Will not work either - it uses lots of non-public API. 

Instead, I used WebChromeClient#shouldInterceptRequest to cache as much resources as possible, which improved loading times quite a bit.
