Replace FragmentPagerAdapter with FragmentStateAdapter in
BrowseTabsAdapter.kt. Refactored getPageTitle as a function that
returns tab name. Tab text update moved to BrowseFragment.
This requires replacement of setupWithViewPager with
TabMediator.attach in BrowseFragment.
Also requires replacing widget declaration
androidx.viewpager.widget.ViewPager with
androidx.viewpager2.widget.ViewPager2 in fragment_browwse.xml.
With Oreo and later, Bluetooth control buttons may kill FFA if it is
not the foreground application. Once this happens to resume playback,
one needs to restart playback from the phone, rather than the
play/pause action of Bluetooth headset.
For example:
