I am trying to delete Group when selected in my Expandable List and having the list refreshed after the delete occurred.

Add the functionality to your Adapter to remove an Item:

    public void removeGroup(int group) {
        //TODO: Remove the according group. Dont forget to remove the children aswell!
        Log.v("Adapter", "Removing group"+group);
        notifyDataSetChanged();
    } 

    public void removeChild(int group, int child) {
        //TODO: Remove the according child
        Log.v("Adapter", "Removing child "+child+" in group "+group);
        notifyDataSetChanged();
    }

Make sure the new methods are accessible to you by changing:

ExpandableListAdapter mAdapter;

to

MyExpandableListAdapter mAdapter;

Call the methods when needed:

 @Override
 public boolean onContextItemSelected(MenuItem item) {
    ExpandableListContextMenuInfo info = (ExpandableListContextMenuInfo) item.getMenuInfo();
    String title = ((TextView) info.targetView).getText().toString();

    int type = ExpandableListView.getPackedPositionType(info.packedPosition);
    if (type == ExpandableListView.PACKED_POSITION_TYPE_CHILD) {
        int groupPos = ExpandableListView.getPackedPositionGroup(info.packedPosition); 
        int childPos = ExpandableListView.getPackedPositionChild(info.packedPosition); 
        mAdapter.removeChild(groupPos, childPos);
        return true;
    } else if (type == ExpandableListView.PACKED_POSITION_TYPE_GROUP) {
        int groupPos = ExpandableListView.getPackedPositionGroup(info.packedPosition); 
        mAdapter.removeGroup(groupPos);
        return true;
    }

    return false;
}

So, hope that helps. Cheers
