将实时视频从RaspberryPi流式传输到我的Android应用程序,但获得安全性异常

我想将实时视频流式传输到我的Android应用程序.我正在使用动作服务从我的覆盆子pi的相机(小型USB连接相机)流式传输实时视频.我有端口8082的设置,所以我可以从任何浏览器成功输入(exampled IP)" http://74.220.185.125:8082 "并看到我的视频流.但是,当我在使用videoView的应用程序的代码中使用它时,每次都会抛出异常.

主要活动:

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        //Starting video
        piVideo = (VideoView) findViewById(R.id.piVidView);

        try{
            piVideo.setVideoURI(Uri.parse("http://74.220.185.125:8082/"));
        } catch (Exception e){
            Log.e("Error found here->", e.getMessage());
            e.printStackTrace();
        }
        piVideo.requestFocus();
        piVideo.start();

        piVideo.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
            @Override

            public void onPrepared(MediaPlayer mp) {
                piVideo.start();
            }
        });


    }

每一次,我都会得到同样的错误:

我的清单文件中启用了INTERNET:

"uses-permission android:name="android.permission.INTERNET"

我已经尝试过rstp://和http://但两者仍然会被抛出相同的异常.任何人都可以看到我的异常可能来自哪里？
