Calling on onDestroy() method in my Expandable list Activity
<p>My AndroidApp containing 5 classes in that 4 activities are normal activities and one activity is ExpandableListActivity ,for the 4 activities am using onDestroy() method and am using below code  </p>

<pre><code>@Override
protected void onDestroy() {
    // TODO Auto-generated method stub
    super.onDestroy();
    unbindDrawables(findViewById("AM using layout id"));  
System.gc();
}

      private void unbindDrawables(View view) {
    if (view.getBackground() != null) {
    view.getBackground().setCallback(null);
    }
    if (view instanceof ViewGroup) {
        for (int i = 0; i &lt; ((ViewGroup) view).getChildCount(); i++) {
        unbindDrawables(((ViewGroup) view).getChildAt(i));
        }
    ((ViewGroup) view).removeAllViews();
    }
   }
</code></pre>

<p>now i want to apply same code for expandablelistactivity class but the problem is am not using any layout ( setContentView(R.layout.ans);) am using below code</p>

<pre><code>public class Mainactivity extends ExpandableListActivity  {

 public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

   // setContentView(R.layout.layout); but am not writing this line

  setListAdapter("adapter am calling");
    }
</code></pre>

<p>and my doubt is how can i implement onDestroy() method as same as above in this class..</p>

<p>please provide any code for that..thanking you</p>
