YoutubePlayer - onError方法没有被调用。

Question

我正在使用YoutubePlayer播放YouTube视频。当互联网不可用时，我想显示一个网络错误对话框。我使用AbstractYouTubePlayerListener回调来侦听网络错误，但是当网络不可用时，不会调用onError方法。我正在为安卓电视开发这个应用程序。

private fun initializePlayer() {
    val customPlayerUi =
        binding.youtubePlayerView.inflateCustomPlayerUi(R.layout.yt_custom_player_ui)
    binding.youtubePlayerView.getYouTubePlayerWhenReady(object : YouTubePlayerCallback {
        override fun onYouTubePlayer(youTubePlayer: YouTubePlayer) {
            this@YoutubeVideoFragment.initializedYouTubePlayer = youTubePlayer
            val customPlayerUiController = YtCustomPlayerController(
                requireContext(),
                customPlayerUi,
                youTubePlayer
            )
            youTubePlayer.addListener(customPlayerUiController)
            if (isEulaAccepted) {
                youTubePlayer.loadVideo(
                    glance.peek.videoPeek.video.youtubeVideo.videoId,
                    videoStartTime.toFloat()
                )
            }
            if (videoItemBinding.nudgeReaction.visibility == View.VISIBLE &&
                videoItemBinding.textPre.text == getString(R.string.skipping_to_next_video)
            ) {
                videoItemBinding.nudgeReaction.setGone()
            }
        }
    })

    binding.youtubePlayerView.addYouTubePlayerListener(object :
        AbstractYouTubePlayerListener() {
        override fun onStateChange(
            youTubePlayer: YouTubePlayer,
            state: PlayerConstants.PlayerState
        ) {
            handleVideoStateChange(state)
        }

        override fun onCurrentSecond(youTubePlayer: YouTubePlayer, second: Float) {
            if (seekRequestedTime == -1 || seekRequestedTime == second.toInt()) {
                // when user starts seeking,running time is getting updated parallely.So,to avoid jerk,will update running time after user seek time is reached
                // else if user is not seeking by default seekRequestedTime will be -1
                updateVideoRunningTime(second)
                seekRequestedTime = -1
            }
        }

        override fun onVideoDuration(youTubePlayer: YouTubePlayer, duration: Float) {
            currentSeekBar.max = duration.toInt()
            updateUIDuration(duration)
        }

        override fun onError(
            youTubePlayer: YouTubePlayer,
            error: PlayerConstants.PlayerError
        ) {
            super.onError(youTubePlayer, error)
            Timber.i("onError: $error")
            setErrorCodes("Youtube error:${error.name}")
        }
    })
}

看起来，onError方法并不能处理此类错误。

这里是定义的错误代码：

    enum class PlayerError {
        UNKNOWN, INVALID_PARAMETER_IN_REQUEST, HTML_5_PLAYER, VIDEO_NOT_FOUND, VIDEO_NOT_PLAYABLE_IN_EMBEDDED_PLAYER
    }

我会先检查网络连接，然后打电话给视频播放器。

试着读一下玩家的状态。如果是缓冲，我就会显示出来。

    enum class PlayerState {
        UNKNOWN, UNSTARTED, ENDED, PLAYING, PAUSED, BUFFERING, VIDEO_CUED
    }
