We had high hopes for nested fragments, especially to support UI interactions like those in the Gmail app: http://stackoverflow.com/q/12253965/2561578

However, in our v1 the only fragments that share an activity are our main feed & story view. All other's have their own activity. It made data flow a lot easier, our manifest file a lot cleaner when filtering for intents, etc.

Interested to hear any tips if you have them!
