Can't I use static and abstaract together?

public abstract class AbstractDataInterface : Fragment, DataInterface
{

    public abstract void SetHandler(int dest, Handler handler);
    public abstract Handler GetHandler(int dest);
    public abstract int SendMessage(Handler handler, int dest, int cmd, Object o);
}

public class RD_TT_AIS_Fragment : AbstractDataInterface
{
    public override Handler GetHandler(int dest)
    {
        return AbstractDataInterface._Handler[dest];
    }

    public class MyHandler : Handler
    {
        public override void HandleMessage(Message msg)
        {
            base.HandleMessage(msg);

            _Handler = GetHandler(AbstractDataInterface.IDX_PROCS_DISP_DATA);
            _Message = _Handler.ObtainMessage();
            _Handler.SendEmptyMessageDelayed(0, 3000);

            Console.WriteLine("+++++++++++++++++++++++++++++++ Menu - A : " + A.Checked);
            Console.WriteLine("+++++++++++++++++++++++++++++++ Menu - B : " + B.SelectedItem);
            Console.WriteLine("+++++++++++++++++++++++++++++++ Menu - C : " + C.Progress);
            //handler.SendEmptyMessageDelayed(0, 200);

        }
    }
}
