[FIXED] @Override must override or implement a supertype

Issue

I am getting an error for @Override, and it is saying i must override or implement a supertype.

This is my code, and the bit that is giving me the error is protected void onNewIntent(Intent intent).

Thanks

 public class CartListActivity extends ListActivity {

        public class ProductListAdapter extends BaseAdapter {

Solution

Method onNewIntent can only be overridden in an Activity. You're extending it in your Adapter. Can you move the method to the Activity class and try it?
