如何使用动态功能模块中的ExoPlayer投射扩展来投射视频

Question

尝试将HLS视频从我的应用程序投射到chromecast时，

我有崩溃。我使用ExoPlayer强制扩展。

我正在使用exoplayer版本2.11.1和播放服务演员框架版本18.0.0。从动态模块调用该代码（在模块的apply plugin: 'com.android.dynamic-feature'中找到build.gradle）。这是我的实现：

当我们创建片段时：

private fun initCast() {
    mediaRouteButton = view?.findViewById(R.id.media_route_button)

    CastButtonFactory.setUpMediaRouteButton(activity?.applicationContext, mediaRouteButton)
    val castContext = CastContext.getSharedInstance()

    castContext?.addCastStateListener { state ->
        if (isAdded) {
            if (state == CastState.NO_DEVICES_AVAILABLE) {
                isCastAvailable = false
            } else {
                isCastAvailable = true
                mediaRouteButton?.visibility = videoTitle.visibility
            }
        }
    }
}

当用户单击“投射”按钮时：

private fun prepareCast(title: String) {
    CastContext.getSharedInstance()?.let {
        castPlayer = CastPlayer(it)
    }

    val movieMetadata = MediaMetadata(MediaMetadata.MEDIA_TYPE_MOVIE)
    movieMetadata.putString(MediaMetadata.KEY_TITLE, title)
    videoThumbnail?.let {
        movieMetadata.addImage(WebImage(Uri.parse(it)))
    }
    val mediaInfo = MediaInfo.Builder(videoUrl)
        .setStreamType(MediaInfo.STREAM_TYPE_BUFFERED)
        .setContentType(MimeTypes.VIDEO_UNKNOWN)
        .setMetadata(movieMetadata).build()

    val mediaItems = arrayOf(MediaQueueItem.Builder(mediaInfo).build())

    castPlayer?.setSessionAvailabilityListener(object : SessionAvailabilityListener {
        override fun onCastSessionAvailable() {
            castPlayer?.loadItems(mediaItems, 0, playerViewModel.getVideoPosition(), Player.REPEAT_MODE_OFF)
            playerViewModel.pauseVideo()
        }

        override fun onCastSessionUnavailable() {
            castPlayer?.currentPosition?.let {
                playerViewModel.setVideoPosition(it)
                playerViewModel.playVideo()
            }
        }
    })
}

[当用户单击我的应用程序中的投射按钮，然后在他们要在对话框中投射的设备上单击时，该应用程序会系统崩溃。这是Stacktrace：

应用程序崩溃仅在Pixel 3和Pixel 3a上出现，但在Samsung S9上没有出现。

有人可以告诉我我想念什么吗？

[经过一周的调查后，打开了两个Github问题（在Glide和ExoPlayer上），我仍然找不到任何解决方案。因此，我最终将[[将Play Services Cast框架版本降级]从18.0.0降为17.0.0。至少我的应用程序stopped crashing，它的运行方式符合我想要的方式。 我希望找到更好的解决方案。
