Java VideoView setVideoUri无内容提供程序

我正在开发一个Android应用程序，需要从本地服务器播放.mp4视频

我有以下代码：

    mPreview = (VideoView) findViewById(R.id.video_preview);
    mPreview.setVisibility(View.VISIBLE);
    mPreview.setVideoURI(Uri.parse("http://192.168.1.100:7676/getVideoByFileName.php?name=C%3A%2FSpinShot%2FResults%2FSpinShot-201701311359177714.mp4"));
    mPreview.setOnPreparedListener(createOnPreparedListener());

    private MediaPlayer.OnPreparedListener createOnPreparedListener() {
        return new MediaPlayer.OnPreparedListener() {
        @Override
        public void onPrepared(MediaPlayer mp) {
            mp.start();
        }
    };
}            

每次执行时，我都会遇到这样的错误：

   D/MediaPlayer: setDataSource IOException | SecurityException happend : 
                                                                         java.io.FileNotFoundException: No content provider: http://192.168.1.100:7676/getVideoByFileName.php?name=C%3A%2FSpinShot%2FResults%2FSpinShot-201701311359177714.mp4

视频视图中不播放视频。任何帮助都将不胜感激。

我的防火墙会影响他们的连接。关闭后，它就可以正常工作。

您可以发布有关如何设置媒体播放器的全部代码吗？@OBX我编辑了代码片段。您在同一网络上吗？我的意思是，当从Android检索视频时，alos会交叉检查您所在的url上是否存在视频using@VivekMishra我查过了。相同的URL在我的电脑浏览器上播放视频。
