How to play a video from url using videoview smoot

Question

I have an activity which has a VideoView . It's playing video from url. What I am doing is for playing smoothly, I have put a ProgressDialog on the start of the activity. And dismisses it inside onPreparedListener so that it would play well and smoothly. But still It's not helping. The video is playing like playing for 10-20 sec and stops for 5-10sec and it keeps going. I have seen an application on Google play Workout Trainer in which if user will start to see the video its showing a horizontal progress bar which buffered the video and then play it smoothly whether it is a slow connection or WI-FI. It requires only to complete that progressbar before starting the video. I want to know how to implement the same thing in my application?

What I am doing is below:

    public class StartExerciseActivity extends Activity {


    protected void onCreate(Bundle savedInstanceState) {
            // TODO Auto-generated method stub
            super.onCreate(savedInstanceState);
            requestWindowFeature(Window.FEATURE_NO_TITLE);
            setContentView(R.layout.show_exercise);
            tileTextView = (TextView) findViewById(R.id.titleText);
            timerTextView = (TextView) findViewById(R.id.timertxt);
            timerRemainTextView = (TextView) findViewById(R.id.timeremaintxt);
            videoView = (VideoView) findViewById(R.id.video_view);
            stopButton = (Button) findViewById(R.id.stopbut);
            pauseButton = (Button) findViewById(R.id.pausesbut);



    progressDialog = ProgressDialog.show(StartExerciseActivity.this, "",
                    "Buffering video...", true);
            getWindow().setFormat(PixelFormat.TRANSLUCENT);

            tileTextView.setText(Constant.NEWS_TITLE);
            timerTextView.setText(Constant.VIDEO_TIME);
            video_url = Constant.VIDEO_NAME;




            try {

                Uri video = Uri.parse(video_url);

                // videoView.setMediaController(mediaController);
                videoView.setVideoURI(video);

                videoView.setOnPreparedListener(new OnPreparedListener() {
                    public void onPrepared(MediaPlayer mp) {
                        progressDialog.dismiss();
                        videoView.start();
                        updateSeekProgress();


                        RelativeLayout.LayoutParams videoviewlp = new RelativeLayout.LayoutParams(400, 400);
                        videoviewlp.addRule(RelativeLayout.CENTER_HORIZONTAL, RelativeLayout.TRUE);
                        videoviewlp.addRule(RelativeLayout.CENTER_VERTICAL, RelativeLayout.TRUE);
                        videoView.setLayoutParams(videoviewlp);
                        videoView.invalidate();


    //                  DisplayMetrics metrics = new DisplayMetrics(); getWindowManager().getDefaultDisplay().getMetrics(metrics);
    //                   android.widget.LinearLayout.LayoutParams params = (android.widget.LinearLayout.LayoutParams) videoView.getLayoutParams();
    //                   params.width =  metrics.widthPixels;
    //                   params.height = metrics.heightPixels;
    //                   params.leftMargin = 0;
    //                   videoView.setLayoutParams(params);
                    }
                });

            } catch (Exception e) {
                progressDialog.dismiss();
                System.out.println("Video Play Error :" + e.getMessage());
            }
 pauseButton.setOnClickListener(new View.OnClickListener() {


                public void onClick(View arg0) {
                    if (count == 0) {
                        videoView.pause();
                        count = 1;
                        pauseButton.setBackgroundResource(R.drawable.playbut);


                    } else if (count == 1) {
                        videoView.start();

                        pauseButton.setBackgroundResource(R.drawable.pausebut);
                        count = 0;
                    }
                }
            });

            stopButton.setOnClickListener(new View.OnClickListener() {


                public void onClick(View arg0) {
                    videoView.stopPlayback();
                    pauseButton.setBackgroundResource(R.drawable.playbut);
                }
            });

        }

Please help. Thanks.

//put in oncreate
