Step #2: Create the Stub Helpcast Activity

Now, we need to add an activity that will use the VideoView widget to

display our video clip.

First, add the following layout as Patchy/res/layout/helpcast.xml:

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:orientation="vertical"

android:layout_width="fill_parent"

android:layout_height="fill_parent"

>

<VideoView

android:id="@+id/video"

android:layout_width="fill_parent"

android:layout_height="fill_parent"

/>

</LinearLayout>

Then, create Patchy/src/apt/tutorial/two/HelpCast.java with the following

code:

package apt.tutorial.two;

import android.app.Activity;

import android.graphics.PixelFormat;

import android.os.Bundle;

import android.os.Environment;

import android.view.View;

import android.widget.MediaController;

import android.widget.VideoView;

import java.io.File;

public class HelpCast extends Activity {

private VideoView video;

private MediaController ctlr;

@Override

public void onCreate(Bundle icicle) {

super.onCreate(icicle);

getWindow().setFormat(PixelFormat.TRANSLUCENT);

setContentView(R.layout.helpcast);

File clip=new File(Environment.getExternalStorageDirectory(),

"helpcast.mp4");

if (clip.exists()) {

video=(VideoView)findViewById(R.id.video);
