Android video not valid for streaming

问题:

i'm trying following code playing video.

public class VidplayerActivity extends Activity {

    private MediaController mc;
    String LINK = "http://***/test.3gp"; // 5 mb 

    @Override
    public void onCreate(Bundle savedInstanceState) {
        try {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.main);
            VideoView vd = (VideoView) findViewById(R.id.delta);

            Uri uri = Uri.parse(LINK);

            mc = new MediaController(this);
            vd.setMediaController(mc);

            vd.setVideoURI(uri);
            vd.start();
        }
        catch(Exception e) {
            System.out.println(e.getStackTrace());
        }
    }

}

it shows "Sorry,this video is not valid for streaming to this device" in android 1.5 and 1.6. And the video details is below

Please read this document : Android Supported Media Formats. Just being encoded using H 263 it is not enough for be in a valid format for streaming in Android.

The resolutions has to be : 176 x 144 px or 480 x 360 px and also at the bottom of the documentation it is stated:

For video content that is streamed over HTTP or RTSP, there are additional requirements:

For 3GPP and MPEG-4 containers, the moov atom must precede any mdat atoms.

For 3GPP, MPEG-4, and WebM containers, audio and video samples corresponding to the same time offset may be no more than 500 KB apart. To minimize this audio/video drift, consider interleaving audio and video in smaller chunk sizes.

try this ::

   mVideoView = (VideoView) findViewById(R.id.surface_view);

        if (path == "") {
            // Tell the user to provide a media file URL/path.
            Toast.makeText(
                    VideoViewDemo.this,
                    "Please edit VideoViewDemo Activity, and set path"
                            + " variable to your media file URL/path",
                    Toast.LENGTH_LONG).show();

        } else {


            mVideoView.setVideoPath(path);
            mVideoView.setMediaController(new MediaController(this));
            mVideoView.requestFocus();

videoview.xml

<VideoView 
    android:id="@+id/surface_view" 
    android:layout_width="320px"
    android:layout_height="240px"
