android - 如何使用 exoplayer 播放本地文件？

Question

我想使用 exoPlayer 播放本地文件（在内部或外部存储中）。我尝试了一些代码，但没有发现任何有用的东西。代码：

getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN);
    String filePath = Constant.allMediaList.get(position).toString();
    Uri videoUrl = Uri.parse(filePath);
    Log.d("filePathLocation",filePath);
    simpleExoPlayer = new SimpleExoPlayer.Builder(this).build();
    DataSpec dataSpec = new DataSpec(videoUrl);
    final FileDataSource fileDataSource = new FileDataSource();
    try {
        fileDataSource.open(dataSpec);
    } catch (FileDataSource.FileDataSourceException e) {
        e.printStackTrace();
    }
    DataSource.Factory factory = new DataSource.Factory() {
        @Override
        public DataSource createDataSource() {
            return fileDataSource;
        }
    };
    simpleExoPlayer.prepare(buildMediaSourceNew(videoUrl));
    playerView.setPlayer(simpleExoPlayer);
    simpleExoPlayer.setPlayWhenReady(true);

buildMediaSourceNew()：

    private MediaSource buildMediaSourceNew(Uri uri){
    DataSource.Factory datasourceFactroy = new DefaultDataSourceFactory(this,
            Util.getUserAgent(this,"Your App Name"));
    return new ExtractorMediaSource.Factory(datasourceFactroy).createMediaSource(uri);
}

使用此代码后，有些文件可以播放，有些则不能。例如：
第一个文件位置：

/storage/emulated/0/Download/Short Animated Film.mp4

第二个文件位置：

/storage/emulated/0/browser/#1 Django tutorials _ What is Django_ _ Python Web Framework.mp4

可以播放第一个文件，但发生以下错误的第二个文件。
如果文件名包含“#”或“？” exoplayer 玩不了。
