For LL-HLS, the non-primary playlists originally keep reloading even after the primary playlist has been changed to another one. The reason being this is to check if the hinted(#EXT-X-PRELOAD-HINT) resource has been published or removed. If removed, the loading of it should be canceled, per the suggestion in the HLS spec: "A Client SHOULD cancel a request for a hinted resource if it is not present in a subsequent Playlist update, such as in an EXT-X-PRELOAD-HINT tag or as part of another tag such as EXT-X-PART. The client SHOULD ignore the results of such requests." However, keeping the non-primary playlists reloading is not optimal. As a solution, we trigger the playlist reloading only when there is a preload chunk loading instead of every time after we have processed the playlist. Compared to the original implementation, this will save the requests of reloading non-primary playlist after we have taken action upon the preload chunk being published or removed.

ExoPlayer HLS module
Provides support for HTTP Live Streaming (HLS) content in ExoPlayer.
Getting the module
The easiest way to get the module is to add it as a gradle dependency:
implementation 'androidx.media3:media3-exoplayer-hls:1.X.X'
where 1.X.X is the version, which must match the version of the other media
modules being used.
Alternatively, you can clone this GitHub project and depend on the module locally. Instructions for doing this can be found in the top level README.
Using the module
Adding a dependency to this module is all that's required to enable playback of
HLS media items added to ExoPlayer in its default configuration. Internally,
DefaultMediaSourceFactory will automatically detect the presence of the module
and convert an HLS MediaItem into an HlsMediaSource for playback.
Similarly, a DownloadManager in its default configuration will use
DefaultDownloaderFactory, which will automatically detect the presence of
the module and build HlsDownloader instances to download HLS content.
For advanced playback use cases, applications can build HlsMediaSource
instances and pass them directly to the player. For advanced download use cases,
HlsDownloader can be used directly.
