Programmatically creating a GridLayout from support library

Question

In android, is it possible to create a GridLayout from the support library entirely programmatically (i.e. without writing corresponding xml)?

I create my GridLayout in a fragment (called PromotionLayoutFragment) like this:

ViewGroup fragmentView = (ViewGroup)getView(); 
GridLayout gridLayout = new GridLayout(fragmentView.getContext());
gridLayout.setColumnCount(2);
gridLayout.setRowCount(15);
// add views to grid ...
fragmentView.addView(gridLayout);

This works fine when i use the GridLayout class present in API level 14, but when I use the GridLayout from the support library (v7-r9), i get:

Turns out that you need to include the GridLayout support library as an Android library project (apklib), instead of a jar. I was using the maven Android SDK deployer, but there is currently an issue open regarding this.
