Answer 2

Recent versions of exoplayer is little different from the above mentioned code.here I have posted a simple code that uses a cloudfront signed HLS m3u8 as media source.

---------- Gradle -----------

def exoplayer_version = "2.17.1"
implementation "com.google.android.exoplayer:exoplayer-hls:$exoplayer_version"
implementation "com.google.android.exoplayer:exoplayer-core:$exoplayer_version"
implementation "com.google.android.exoplayer:exoplayer-ui:$exoplayer_version"

----------- XML [define a ui.PlayerView] -----------

[....]
    <com.google.android.exoplayer2.ui.PlayerView
         android:id="@+id/ep_video_view"
         android:layout_width="match_parent"
         android:layout_height="wrap_content"
         app:layout_constraintBottom_toBottomOf="parent"
         app:layout_constraintEnd_toEndOf="parent"
         app:layout_constraintStart_toStartOf="parent"
         app:layout_constraintTop_toTopOf="parent" />
[....]

------------ Fragment ------------

    private var exoPlayer: ExoPlayer? = null

[...] 

        val sourceURL= "https://a.cloudfront.net/b.m3u8?Policy=eyJT..._&Signature=eZ6....__&Key-Pair-Id=KRSDW..."
// extract Policy, Signature and KeyPairIds
        val uri: Uri = Uri.parse(sourceURL)
        val policyString: String? = uri.getQueryParameter("Policy")
        val signatureString: String? = uri.getQueryParameter("Signature")
        val keyPairIdString: String? = uri.getQueryParameter("Key-Pair-Id")

// Create a cookie list to send

        var cookieValue = ""
        cookieValue += "CloudFront-Policy=$policyString;"
        cookieValue += "CloudFront-Signature=$signatureString;"
        cookieValue += "CloudFront-Key-Pair-Id=$keyPairIdString;"

// httpDataSourceFactory

        val httpDataSourceFactory: HttpDataSource.Factory =
            DefaultHttpDataSource.Factory()
                .setDefaultRequestProperties(mapOf("Cookie" to cookieValue))
                .setAllowCrossProtocolRedirects(true)

        val dataSourceFactory = DefaultDataSource.Factory(requireContext(), 
                                httpDataSourceFactory)

        val hlsMediaSource: HlsMediaSource = 
             HlsMediaSource.Factory(dataSourceFactory)
            .createMediaSource(MediaItem.fromUri(sourceURL))

        exoPlayer = ExoPlayer.Builder(requireContext()).build()

        exoPlayer.also { exoPlayer ->
            binding.epVideoView.player = exoPlayer
            exoPlayer?.addMediaSource(hlsMediaSource)
            exoPlayer?.prepare()
            exoPlayer?.playWhenReady = true
        }

[...]

Incase if you get any 403 from exoplayer, try changing the userAgent in httpDataSourceFactory
