title: Android TextView textAlilgnment
body: <p>I have an old Android project which has used the textAlignment property for years to center text in a TextView.  It has just been brought to my attention that this no longer works, and the text now display as left aligned.</p>
  <p>I can fix this with the <em>gravity</em> property, but is this a known change???  I am concerned there might be other changes that need to be addressed, that I am not aware of.</p>
  <p>FYI - I'm targeting 29.</p>
