Playing a video in VideoView in Android

I can't figure out why I'm not able to play the video in my VideoView. All I'm getting for a message is:

Cannot Play Video : Sorry, this video cannot be played.

I created an SD card for my emulator as well. Do I need to place my SD card in a particular folder in my SDK? Please comment.

Here's the layout:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 
   android:id="@+id/LinearLayout01"
   android:layout_height="fill_parent"     
   android:paddingLeft="2px"
   android:paddingRight="2px"
   xmlns:android="http://schemas.android.com/apk/res/android"
   android:paddingTop="2px"
   android:paddingBottom="2px"
   android:layout_width="fill_parent"
   android:orientation="vertical">

      <VideoView 
         android:layout_height="fill_parent"
         android:layout_width="fill_parent" 
         android:id="@+id/VideoView" />

</LinearLayout>

Here's the code:

package com.examples.videoviewdemo;

import android.app.Activity;
import android.os.Bundle;
import android.widget.MediaController;
import android.widget.VideoView;

public class VideoViewDemo extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        VideoView videoView = (VideoView)findViewById(R.id.VideoView);
        //MediaController mediaController = new MediaController(this);
        // mediaController.setAnchorView(videoView);
        //videoView.setMediaController(mediaController);

        videoView.setVideoPath("/sdcard/blonde_secretary.3gp");

        videoView.start();  
    }
}

Waiting for the reply...
