Not to call onDestroy on onBackPressed

Question

I don't want my acivity to get destroyed when Back button is pressed. My app is compatible from 1.6 SDK's. Referring to http://android-developers.blogspot.com/2009/12/back-and-other-hard-keys-three-stories.html and Override back button to act like home button, I opted the following code :

    @Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
                // For versions lower than 2.0     
    if (Utility.buildDet.getDeviceBuildAPI() <= Utility.buildDet.getBuildApi() 
            && keyCode == KeyEvent.KEYCODE_BACK && event.getRepeatCount() == 0)
        onBackPressed();
    return super.onKeyDown(keyCode, event);
}

      // In any version, this function will be called
public void onBackPressed() {
    // This will be called either automatically for you on 2.0    
    // or later, or by the code above on earlier versions of the platform.
    Log.i(TAG, "##### BACK KEY IS PRESSED");
    this.moveTaskToBack(true);  // on false, it shows moveTaskToBack: 11
    return;
}

When I press Back button, I these logs

: ##### BACK KEY IS PRESSED
 INFO/ActivityManager(51): moveTaskToBack: 10
: !!!!!!! Into onPause
: !!!!!!! Into onStop
: !!!!!!! Into DESTROY

I have not overridden moveTasToBack(). Anu clu what do I do to not get destroyed when back button is pressed. Maybe I want to just ignore the button or hide the activity.

Any clue, why it is not working as expected.

Thanks

public boolean onKeyDown(int keyCode, KeyEvent event)  
{

     if (keyCode == KeyEvent.KEYCODE_BACK && event.getRepeatCount() == 0)
     {

        this.moveTaskToBack(true);
           return true;
      }

    return super.onKeyDown(keyCode, event);
}
