</pre>

The main goal of this change set was to use more of android's best practices (I,II,III).  The second goal was to improve performance (IV, V).  Finally I was hoping to improve development experience (I,VI).

The "Advanced JSON format" vs Fit is not part of this changeset sorry for any confusion.
