Before the thumbnail finishes loading for the new video the player is now playing, the old thumbnail was being used, leading to wrong thumbnails set in the media session and the notification.
Before the Target would sometimes be garbage collected before being called with the loaded channel icon, since Picasso holds weak references to targets. This meant that sometimes a new streams notification would not be shown, because the lambda that should have shown it had already been garbage collected.
- Show placeholders until the image is loaded because timeout can be very long and missing profile pictures and video thumbnails make app inconvenient to use
- Adapt profile picture and video thumbnail placeholders to light theme
- Replace profile picture and video thumbnail placeholders with vector graphics
These previews will be only available for images cached in the cache used by Picasso.
The Bitmap of the content is compressed in JPEG 90 and saved inside the application cache folder under the name android_share_sheet_image_preview.jpg.
The current image will be, of course, always overwritten by the next one and cleared when the application cache is cleared.
Removed some non-translatable strings and just hardcoded them in the code, like it's being done for other string separators. This also deduplicates some code by using Localization.
Used some Kotlin feature to reduce code.
