Update – August 2016
I first wrote this post shortly after textinputlayout was introduced and there was a distinct lack of documentation. My original code example for setting the error was incorrect. Per Victor Tsaran:
There is no such attribute as android:setError. There is a method called setError in the View class that can set the error message dynamically. That method actually works with TalkBack.
I will be updating the code examples soon. For now, do not include the android:seterror line shown below. I’m leaving it right now for archival purposes.

They’ve also begun rolling out new APIs that make it much easier to implement the interaction designs within Android and HTML. However, there are still some gaps. This article looks at the popular Text Input for Android interaction. Please note: the code in this article is not fully documented and the best practice may change as the Google Accessibility team updates their documentation. Consider this a beta pattern and I will gladly update it as we learn better practices.
