- 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
- status bar got a fix for situation when a phone vendor did not provide status bar height for landscape orientation
- popup will not be init'd twice
- also fixed some non-reproduceable bugs
- main, background, popup players now connected via one service, one view, one fragment, one activity and one gesture listener
- playback position is synchronized between players. Easy to switch from one to another
- expandable player at the bottom of the screen with cool animation and additional features like long click to open channel of a video, play/pause/close buttons and swipe down to dismiss
- in-player integrated buttons for opening in browser, playing with Kodi, sharing a video
- better background playback that can be activated in settings. Allows to automatically switch to audio-only mode when going to background and then switching to video-mode when returning to the app.
