I assumed that the webview controller would automatically fit the html contents horizontally and would allow only vertical scrolling. But that doesn’t seem to be the way. You can ofcourse set the below values to make it horizontally fit: (available from 2.1)
webview.getSettings().setLayoutAlgorithm(LayoutAlgorithm.SINGLE_COLUMN); should be an easier option, but it’s not working on 2.1. There was a bug raised (link) was fixed in 2.2 only.
