TextInputLayout uses TextUtils.writeToParcel() to save the Error message, which writes a least am integer and the String, while it just reads a String when restoring the sate.

Steps to reproduce:
Set "Do not keep activities" to on Developer options, run https://github.com/luciofm/TextInputLayoutBug, enter some text on one of the fields, press home, come back, press home, come back and the app Crashes.
