For all manually-created images PNG have been kept.
- rename all icon attrs to have a `ic_` prefix
- always use `_24dp` icons, because there is no real difference, since they are vector drawables
- always use the original name found on material.io for icon drawables, as to not create confusion and possibly duplicates. Icon names can still be different from real drawable names, though I have made some of them compliant to this or maybe more meaningul.
- remove duplicate `getIconByAttr()` in ThemeHelper (use `resolveResourceIdFromAttr()`
- use standard icons for `expand_more` and `expand_less` instead of triangles
- use `play_button_outline` instead of custom PNG as play button in VideoDetailFragment (questionable, as there is no shadow anymore)
- added autoplay options inside settings: always, only on wifi, never
- now statusbar will be shown in fullscreen mode
- playlists, channels can be autoplayed too (if enabled)
- changed title of background activity to Play queue
- fixed a crash
Common actions and labels are now in a unique enum: StreamDialogEntry
If an action is not common to every long-press menu (e.g. delete) a custom action has to be provided using e.g. delete.setAction(...)
- add HistoryInfoItem (deriving from StreamInfoItem)
in order to add a special options menu for the list items
- delete HistoryActivity and everything that belongs to its UI (not the
manager tho)
- put everything that is local into local. (subscriptions still missing)
