java.lang.ClassCastException: android.app.Application cannot be cast to greendroid.app.GDApplication

I'm getting a class cast exception namely

java.lang.ClassCastException: android.app.Application cannot be cast to greendroid.app.GDApplication

when I'm trying to use the green droid library in my project.Here is the concerned code. I've been trying to figure out what is going wrong but still no luck. Any sort of help will be much appreciated. Thank you.

public class MainMenu extends GDActivity{
   private QuickActionWidget mBar;
@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setActionBarContentView(R.layout.mainmenu);
       mBar = new QuickActionBar(this);
       mBar.addQuickAction(new QuickAction(this, R.drawable.food, "food"));

Button foodButton=(Button)findViewById(R.id.food);




foodButton.setOnClickListener(new View.OnClickListener() {

@Override
public void onClick(View v) {
    // TODO Auto-generated method stub
     mBar.show(v);

}
 });


}

  }

Here is my mainmenu.xml

   <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"

        android:layout_height="wrap_content"

        android:id="@+id/menu"
        android:background="@drawable/menu"></Button>

        android:id="@+id/food"
        android:layout_toRightOf="@id/menu"
        android:background="@drawable/food"></Button>   

</RelativeLayout>
</LinearLayout>

This my LogCat.

I can only guess. Does you android app extends GDApplication ?

For example (in AndroidManifest.xml):

<application
        android:icon="@drawable/ic_gdcatalog"
        android:label="@string/app_name"
        android:theme="@style/Theme.GDCatalog"
        android:name=".CatalogApplication">
...
...

You should in your class do this:

public class CatalogApplication extends GDApplication {

    @Override
    public Class<?> getHomeActivityClass() {
        return CatalogActivity.class;
    }

    @Override
    public Intent getMainApplicationIntent() {
        return new Intent(Intent.ACTION_VIEW, Uri.parse(getString(R.string.app_url)));
    }

}

You can also download GDCatalog sample Application and run it in Eclipse.
