TextInputLayout Issues with setError

README.md

This is a gist that was built for my post on TextInputLayouts here: http://w3bshark.com/blog/input-layouts

It is an example of how making back-to-back calls to the setError() functionality for the same text input layout will cause the text input layout to only display the error that was set originally instead of the final error that was set.
