Dbrant has uploaded a new change for review. (
https://gerrit.wikimedia.org/r/375081 )
Change subject: Update compilation metadata in Local activity, as well as
Remote.
......................................................................
Update compilation metadata in Local activity, as well as Remote.
A couple of things:
- This updates LocalCompilationsFragment to request compilation metadata,
so that any new packs that are discovered will immediately be updated
with correct information.
- Guard agains fragment destruction in Local and Remote callbacks.
- In the Compilation class, let's make the Date be @NonNull, because this
class needs to be serialized by Gson for saving to Prefs (when
persisting cached compilations), and a null Date does not serialize
well; in fact it crashes.
Bug: T174716
