The application programming interface operates in an environment with user interface software interacting with multiple software applications or processes in order to synchronize animations associated with multiple views or windows of a display of a device. The method for synchronizing the animations includes setting attributes of views independently with each view being associated with a process. The method further includes transferring a synchronization call to synchronize animations for the multiple views of the display. In one embodiment the synchronization call includes the identification and the number of processes that are requesting animation. The method further includes transferring a synchronization confirmation message when a synchronization flag is enabled. The method further includes updating the attributes of the views from a first state to a second state independently. The method further includes transferring a start animation call to draw the requested animations when both processes have updated attributes.
