ListenableResultFuture

AI-generated Key Takeaways

• ListenableResultFuture extends the standard Future to provide a callback mechanism for results.

• Results are delivered to the OnResultListener provided via setOnResultListener, ensuring execution on the UI thread.

• It inherits methods from Future for managing task cancellation and retrieving results (e.g., get(), cancel()).

• This interface facilitates asynchronous operations with UI updates by simplifying result handling on the main thread.

public interface ListenableResultFuture implements Future<T>

A Future that accepts an onResult listener that will be called on the UI thread.
