The issue here, still happening on 2.1.5

[mhelmi]

The problem happened for me when I observe loadingLiveData to start or stop animation if I transaction another fragment and back to the fragment that included the CircleProgressButton it's start to observe loadingLiveData variable again and get the last value and try to revert morph animation while the current state is stop so it's crashes and give the above error.

I solved this problem by check the state before morph, so the btn can't start morph while it's not morph any more.
The working check solution for my case was:

if (btn.getState().equals(State.MORPHING) || btn.getState().equals(State.PROGRESS)) btn.startMorphRevertAnimation();

Sorry, taking so long for the reply. I'll take a look as soon as I can.

[uncledoc]

I have the same issue on android 4.2.2

[chetan3333]

The same issue is happening to me as well

[mhelmi]

it there any update for this issue? @leandroBorgesFerreira
I have faced it when I am using btn in the adapter and try to update adapter to start loading

[leandroBorgesFerreira]

Sorry for the late response... I can't reproduce it in the sample app. I fire the start animation inside the onCreate of an activity and it works just fine =|

Maybe inside a fragment... Let's see.

I' have the same issue in version 2.2.0

[josechagas]

It seem like I could prevent that crash by calling button to dispose in onDestroyView :
override fun onDestroyView() { super.onDestroyView() progressButton.dispose() }
FYI : use in Fragment

This crash happened when I call dispose in onDestroy :
override fun onDestroy() { super.onDestroy() progressButton.dispose() }
