You asked me if it is supported, and I said yes.
I have tested it and it works fine in 4.4. It may be due to other reasons

If you can pull it down to prove that there is no problem, see if you did a lot of calculations in onRefresh.
If it can be asynchronous, do it asynchronously. Don’t block the UI thread
