Question

我正在使用exoplayer播放sd卡中的视频。出现问题。看来exoplayer正在缓冲sd卡中的视频，如果我使用音轨选择器向前移动到未缓冲的部分，则视频会停止缓冲并抛出异常：

这是我的代码

      PlayerView playerView;
SimpleExoPlayer simpleExoPlayer;
@Override
protected void onStart() {
    super.onStart();x
   playerView=(PlayerView)findViewById(R.id.ff);
    simpleExoPlayer= ExoPlayerFactory.newSimpleInstance(this,new DefaultTrackSelector());
    playerView.setPlayer(simpleExoPlayer);

    /*DefaultDataSourceFactory defaultDataSourceFactory=new DefaultDataSourceFactory(this, Util.getUserAgent(this,"ExoPlayer"))
    ExtractorMediaSource   extractorMediaSource=new ExtractorMediaSource(defaultDataSourceFactory)
            .creatMediaSource(Uri.parse());*/

    String playerInfo = Util.getUserAgent(this, "ExoPlayerInfo");
    DefaultDataSourceFactory dataSourceFactory = new DefaultDataSourceFactory(
            this, playerInfo
    );
    MediaSource mediaSource = new ExtractorMediaSource.Factory(dataSourceFactory)
            .setExtractorsFactory(new DefaultExtractorsFactory())
            .createMediaSource(Uri.parse(Environment.getExternalStorageDirectory().toString()+"/gfdf2.mp4"));
    simpleExoPlayer.prepare(mediaSource);
    //simpleExoPlayer.setPlayWhenReady(true);

}

@Override
protected void onStop() {
    super.onStop();
    playerView.setPlayer(null);
    simpleExoPlayer.release();
    simpleExoPlayer=null;


}
      }

这是我的日志

我是exoplayer的新手，所以请回答尽可能简单：）
