[android-developers] Newbie having trouble launching new activity, application stops unexpectedly

New to programming in Android and having trouble launching
a video to play activity. I am pulling what remains of my hair out
so any help or advice would be greatly appreciated as I have tried
all sorts and scanned the net for days bu have not come up
with the answer and I bet it's a simple answer.

Basically I have a touch screen that is mapped by a file
to give touch areas that select a video to play. All this
mapping and touch code works.

When I touch an activated area I get the following message:-

==============================================
Sorry
The application video_4 (process org.example.
video_4) has stopped unexpectedly. Please try
again.

Force close.
==============================================

When I looked in my book it says if this happens its because
I have not defined my activity in the manifest file. This I
think I have done.

Here is my manifest file:-

====================
video_4 manifest.xml
====================
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="org.example.video_4"
android:versionCode="1"
android:versionName="1.0">
<application android:icon="@drawable/icon" android:label="@string/
app_name">
<activity android:name=".video_4"
android:label="@string/app_name"
android:theme="@android:style/Theme.NoTitleBar.Fullscreen">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category
android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>

===========> here is where I think the video activity is defined

<Activity android:name=".Videos"
android:label="@string/video_play"
android:theme="@android:style/Theme.NoTitleBar.Fullscreen">
</Activity>

</application>
<uses-sdk android:minSdkVersion="4" />
</manifest>

================================
Here is my touch code this works
================================
@Override
public boolean onTouchEvent( MotionEvent event ){
int xpos,ypos;

if( event.getAction() != MotionEvent.ACTION_DOWN ){
return super.onTouchEvent( event );
}
xpos = (int)event.getX() / 20;
ypos = (int)event.getY() / 20;
if( xpos < 0 || xpos > 39 || ypos < 0 || ypos > 23 || !ready ){
return true;
}
if( videos_to_play[ ( ypos * 40 ) + xpos ] < 8 ){
video_to_play = videos_to_play[ ( ypos * 40 ) + xpos ];
Intent a = new Intent( this , Videos.class );
startActivity( a ); <====== line that causes the error on
running
}
return true;
}

==========
videos.xml
==========
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<VideoView
android:id="@+id/vidview"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_gravity="center"
/>
</FrameLayout>

===========
videos.java
===========
package org.example.video_4;

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

public class Videos extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView( R.layout.videos );
VideoView video = (VideoView) findViewById( R.id.vidview);
video.setVideoPath(/*"/LocalDisk/AdBook/v4.mp4"*/"/sdcard/AdBook/
v4.mp4");
video.start();
}
}
