By changing this interface from default scope to public it would allow for the creation of alternate paging implementations to reuse the same adapter to its full extent. At present this only prevents notifying the view of adapter changes.

As a workaround, I am currently using the following class

    package android.support.v4.view;

    public final class PagerAdapterPublicCompat {
        private PagerAdapterPublicCompat() {}

        public interface DataSetObserver extends PagerAdapter.DataSetObserver {}

        public static void setDataSetObserver(PagerAdapter adapter, DataSetObserver observer) {
            adapter.setDataSetObserver(observer);
        }
    }
