spin() does not work

[XtreeIvI]

spin() does not work after I set at least once setInstantProgress(SOME_VALUE). If I do not call setInstantProgress at all spin works as intended. I used ProgressWheel along with "in.srain.cube:ultra-ptr:1.0.11". In pull to refresh (ptr) mentioned I use first linear progress. Right before ptr is going to be refreshed I turned off linear progress and start spin(). It does not work. I have tried to setProgress(0.0F) and setInstantProgress(0.0F) before calling spin(). It also does not help. I have tried to post spin() in Handler. No help as well.
