Futuroid - Android library for asynchronous tasks

Futuroid is an Android library that allows running asynchronous tasks and attaching callbacks thanks to a convenient syntax. It offers an alternative to the Android AsyncTask class.

Features

  • Future-based API (similar to Guava's ListenableFutures, Scala/Akka Futures, Javascript promises...)
  • Allows registering callbacks to be run on the Android UI/main thread
  • Provides a default ExecutorService (fixed thread pool with 5 threads) that can be replaced by a custom one
  • Each task can be run on the default ExecutorService or on a custom one
  • Allows task chaining (monad-style)

Sample code

Image download asynchronous service:

    public class DownloadService {
        
        /**
         * Downloads an image asynchronously.
         */
        public Future<Bitmap> downloadImage(String url) {
            return Async.submit(new Callable<Bitmap>() {
                @Override
                public Bitmap call() {
                    Bitmap bitmap;
                    
                    // HTTP request goes here...
                    
                    return bitmap;
                }
            });
        }
    }

Client code:

    // download an image from a URL
    imageService.downloadImage(url).addCallback(new FutureCallback<Bitmap>() {
        @Override
        public void onSuccess(Bitmap bitmap) {
            // display the image
            imageView.setImageBitmap(bitmap);
        }

        @Override
        public void onFailure(Throwable t) {
            Log.e(TAG, "Unable to download image", t);
        }
    });
