Method Detail

addListener

public LottieTask<T> addListener(LottieListener<T> listener)

Add a task listener. If the task has completed, the listener will be called synchronously.

Returns:

the task for call chaining.

removeListener

Remove a given task listener. The task will continue to execute so you can re-add a listener if neccesary.

Returns:

the task for call chaining.

addFailureListener

Add a task failure listener. This will only be called in the even that an exception occurs. If an exception has already occurred, the listener will be called immediately.

Returns:

the task for call chaining.

removeFailureListener

public LottieTask<T> removeFailureListener(LottieListener<java.lang.Throwable> listener)

Remove a given task failure listener. The task will continue to execute so you can re-add a listener if neccesary.
