我认为最好使用资产文件夹来存放媒体文件 我希望这段代码可以帮助你。

String videoPath = "your_video_filename.mp4"; // Replace with your video file name
    AssetFileDescriptor assetFileDescriptor;
    try {
        assetFileDescriptor = getAssets().openFd(videoPath);
        videoView.setVideoURI(Uri.parse("asset:///" + videoPath));
        videoView.setMediaController(new MediaController(this));
        videoView.requestFocus();
        videoView.start();
    } catch (IOException e) {
        e.printStackTrace();
    }
}

它使用videoview 替换为exoplayer
