The successor of vudroid is called ebookdroid.
There are a lot of other programs like offline Wikipedia
(WikiDroyd,Aard Dictionary) that use the plain Android Webkit/WebView
component for display. Every scroll and page turn results in a lot of
page refreshes and flicker. The success of e-ink devices crucially
depends on this.
