- mini player's title, image and author information will be updated in many situations but the main idea is that the info will be the same as currently playing stream. If nothing played then you'll see the info about currently opened stream in fragment. When MainPlayer service stops the info updates too
- made ExpandableSurfaceView to replace AspectRatioFrameLayout. The reason for that is to make possible to use aspect ratio mode ZOOM. It's impossible to show a stream inside AspectRatioFrameLayout with ZOOM mode and to fit the video view to a screen space at the same time. Now the new view able to do that and to show vertical videos in a slightly wide space for them
- refactored some methods to make the code more understandable
- made fixes for player view for landscape-to-landscape orientation change
- added Java docs
- adapted swipe tracking inside bottom sheet
- fixed PlayQueue crashes on clearing
- paddings for popup player now as small as possible
- wrote more methods to PlayQueue. Now it supports internal history of played items with ability to play previous() item. Also it has equals() to check whether queues has the same content or not
- backstack in fragment is more powerful now with help of PlayQueue's history and able to work great with playlists' PlayQueue and SinglePlayQueue at the same time
- simplified logic inside fragment. Easy to understand. New PlayQueue will be added in backstack from only one place; less number of setInitialData() calls
- BasePlayer now able to check PlayQueue and compare it with currently playing. And if it is the same queue it tries to not init() it twice. It gives possibility to have a great backstack in fragment since the same queue will not be played from two different instances and will not be added to backstack twice with duplicated history inside
- better support of Player.STATE_IDLE
- worked with layouts of player and made them better and more universal
- service will be stopped when activity finishes by a user decision
- fixed a problem related to ChannelPlayQueue and PlaylistPlayQueue in initial start of fragment
- fixed crash in popup
