Android WebView renders blank/white, view doesn't update on css changes or HTML changes, animations are choppy

Question

When ever I make a css class change, the changes don\'t always appear. This appears to happen when I have a touch event that adds something like a down class name to a butto

Answer 1

Please also see my answer at WebView fails to render until touched Android 4.2.2 , The idea is to export @Olivier's function to JavaScript so you can trigger invalidates from JS in sensible parts ... My god, yet another more hack !! :)
