Also made sure that register/unregister are called in onStart/onStop
instead of onResume/onPause (prevents possible MultiWindow problems
where updates are not received because activity is not fucused).
Need to wrap return result with Optional<>
Mark code path with TODO. Actual fix is pending #2954 merge.
Rx observer: underlying sources that need to return Optional<>
OnlineFeedViewActivity.parseFeed : <anonymous subscriber>
PlaybackController.bindToService : fixed in #2954
should never happen in the code path, e.g.,
return the current FeedItem in ItemFragment UI.
Mark underlying method as @Nullable, and let observer's existing
onError() to handle null case
Rx observer : underlying sources marked as @Nullable
ItemFragment.load : .loadInBackground
MediaplayerActivity.checkFavorite : DBReader.getFeedItem
ItemDescriptionFragment.onViewCreated : DBReader.getFeedItem
ItemlistFragment.loadItems : .loadData
to be on the safe side, for cases that the consuming observers checks null
unnecessarily.
Rx observer : underlying sources marked as NonNull
OnlineFeedViewActivity.startFeedDownload : Downloader.getResult
AllEpisodesFragment.loadItems : AllEpisodesFragment.loadData
PlaybackHistoryFragment.loadItems : DBReader.getPlaybackHistory
QueueFragment.loadItems : DBReader.getQueue
SearchFragment.search : .performSearch
to be on the safe side, for cases that the consuming observers
already assumes the result is not null.
Rx observer : underlying sources marked as NonNull
OnlineFeedViewActivity.listener member : DBReader.getFeedList
