VideoView setVideoUri没有内容提供商

Question

我正在开发一个Android应用程序，需要从我的本地服务器播放.mp4视频。

我有这个代码：

    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，我都会收到此错误：

   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
