I don't see a lot of documentation, but here's an old blog post introducing the system: http://google-opensource.blogspot.com/2009/10/talkback-open-source-screenreader-for.html

Briefly tried enabling it on my Nexus 1 (Android 2.3.6). It seems highly dependent on keyboard navigation, which we're currently really bad at on Android for some reason.

Tapping into the search field reads out "edit box web view", and.... that's about it. Ugh!

On the other hand, the system Browser app seems to have the same fate. "Browser. Web view." and ...... nothing more even as I navigate through the document and links using the thumbwheel.

There may be little or nothing we can do; it doesn't seem comparable to iOS's VoiceOver which can actually read text from the web views (though we have some issues with selection and interaction there too)

Slightly more advanced in Android 4.0 with the "explore by touch" feature, but it still reads nothing out of the web views, including in the stock Browser application.

New app should be friendlier to this system, though we'd still have to do some research.

Thanks for the note. We'll keep it in mind as we design the new Wikipedia App. Resolving as this was cut against a deprecated code base.
