See how time you could have saved? — Simon, Apr 06 '13 at 20:35
@Elior infect i did never use log even did not know to read it .hopefully next time i will track problem myself — Sikander, Apr 06 '13 at 20:45
is the menu class should appear after the animated intro? i think that you declare in the manifest.xml a Menu class but you didn't refernce that to the java class.. so it doesn't know from where to load the Menu class, please post your manifest.xml file — Elior, Apr 06 '13 at 21:29
@Elior yes that would go to Menu.java , i have added Activity in maunfest.xml .. now only screen loads animation does not work as expected and Does not go to Menu.java — Sikander, Apr 07 '13 at 09:40
in my opinion, you need to create a separate activity for the intro screen, and when the movie's end, close the intro activity with the finish() method, and then load the menu activity.. — Elior, Apr 07 '13 at 10:37
this activity is for intro , and when finishes goes to menu that is separate one .. public void onAnimationEnd(Animation animation) { startActivity(new Intent(MainActivity.this, Menu.class)); MainActivity.this.finish(); } — Sikander, Apr 07 '13 at 10:43

The problem is that you didn't declare the Activity in your Manifest

04-06 20:18:25.996: E/AndroidRuntime(812): android.content.ActivityNotFoundException: Unable to find explicit activity class {com.example.simplegame/android.view.Menu}; have you declared this activity in your AndroidManifest.xml?

UPDATED

add this to your manifest. and replace package name with your package name which is like com.etc.xxx

    <activity
        android:name="*package name*.Menu"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MENU" />
            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </activity>

You did not create the activity in the AndroidManifest.xml.

This link should help you: Best way to add Activity to an Android project in Eclipse?

Remember Google is your friend, make an effort to learn things on your own, it will benefit you in the long run.

         <category android:name="android.intent.category.LAUNCHER" />
       </intent-filter>
   </activity>
   <activity
       android:name= "com.example.simplegame.Menu" <!-- java file-->
       android:label="@string/app_name">
       <intent-filter>
         <action android:name="thePackageOfTheLayoutsXmlFiles.MENU"/> <!-- layout -->
         <category androi:name = "android.intent.category.DEFAULT"/>
      </intent-filter>
   </activity>
 </application>     
 </manifest>

in the manifest file you forgot to refernce the layout to the java file.. also, when you want to add a new activity to your app, you need to create a new xml file for the layout.. and new java class, this class should extends the Activity and then add to this class the onCreate() method..
