animateProgress problem when receiveing a broadcast

There is a service in my app that contains an Asynctask that sends a broadcast during onProgressUpdate. I want to show the progress in an ArcProgressStackView in a fragment that receives the broadcast. The problem is that the progress bar is updated but it doesn't show the animation during the update between an updated number to another. As a note, If I don't send the broadcast, the progress bar, of course, doesn't show the progress, but the animation is shown from 0 immediately to 100 after analysis finished. I mean it seems that updating the progress bar from a service by a broadcast receiver is affecting on the animation.

Would you please let me know what I am missing?

Comece reproduzindo o fluxo de atualização do progresso entre o AsyncTask onProgressUpdate do serviço, o broadcast e o ArcProgressStackView do fragmento. Rastreie como cada valor recebido chega à visualização de progresso e compare isso com atualizações diretas; considera-se concluído quando uma alteração concreta que preserve a animação entre as atualizações for identificada e documentada.
