Here's the activity class

public class VideoViewDemoProj extends Activity {
    private static final String TAG = "VideoViewDemo";

    private VideoView mVideoView;
    private EditText mPath;
    private ImageButton mPlay;
    private ImageButton mPause;

    private String current;

    @Override

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

        mPath = (EditText) findViewById(R.id.path);
    //  mPath.setText("http://logisticinfotech.com/extra/Veer.mp4");
    //  mPath.setText("http://www.youtube.com/watch?v=rkOySwlEtVk&feature=youtube_gdata_player");
        mPath.setText("http://logisticinfotech.com/client/full-volume.mp4");
        mPlay = (ImageButton) findViewById(R.id.play);
        mPause = (ImageButton) findViewById(R.id.pause);
        mReset = (ImageButton) findViewById(R.id.reset);
        mStop = (ImageButton) findViewById(R.id.stop);

        mPlay.setOnClickListener(new OnClickListener() {
