The plans for widgets have changed somewhat. Instead of 4 or so
variants, there will instead be one unified widget that chooses
different layouts depending on its size. The first one added is the
full widget, which shows more controls as long as theres enough
space.
Modify the minimal wdiget so that it can work on Android 11 and below.
Was not actually that hard, mostly changing layouts around all things
considered. This also splits up the default view and the main widget
views, which makes managing UI state much easier.
Use viewLifecycleOwner for all fragments that rely on databinding. This
should solve some possible memory leaks, as viewLifecycleOwner is tied
to the lifecycle of the fragment views instead of the fragments them
selves.
