This package contains an updated implementation of the contract fragment pattern put forward by @JakeWharton that uses the parent fragment or the activity to check for a contract implementation. See the original idea on jakes github

This package also contains a base Fragment and DialogFragment implementation with bug fixes for child fragment animations and immersive dialog fragments. Learn more about these bugs here and here

If new fragment related ui issues pop up, I'll be sure to address them in these base classes.
