This library extends AsyncTask api.


  • You can handle task's priority in task queue (from fifo queue to priority queue).
  • You can handle running thread's priority for task.
  • You can set a timer for task.

Satellite is a simple (for those who are familiar with RxJava) Android library, which allows to properly connect background tasks with visual parts of an application.

Caesar is a tiny Java library that allows to create an asynchronous proxy-version of some synchronous bean. It means that you can still think in terms of your service/bean/object and use its methods instead of writing concurrency code.

An utility library for Android to run actions in background. It handles orientation changes and delegates results to the visible Activity.

AsyncManager hopes to keep management of background threads as simple as possible, by keeping the creation and termination of background tasks to just one API call respectively. Callback, which will be processed on the UI thread, can be overridden to process the result returned from the background operation.

Coordinator is a Java library that is used to coordinate various asynchronous actions. Usually we found cases that you need to check if other thread is completed to execute an action, coordinator solves this problem without using flags.

Extremely light way to execute code in the background on Android. Alternative to AsyncTask.

Small Android library for use the Interactor (use case) and Executor for running code on a ThreadPool Thread or UI Thread. Normally this library is used for implement the Clean Architecture.

JDeferred is a Java Deferred/Promise library similar to JQuery's Deferred Object.

android-asyncservice manages threading and caching transparently in your Android app.

It's an alternative to AsyncTasks, Loaders, or more advanced libs like RxJava, Robospice, Groundy, … but AsyncService focuses on keeping your code short and simple!

What is Android Promise

A library for modular asynchronous calls.

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.


  • 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)

Android library to easily queue background and UI tasks.

So what does it exactly do?

If you are working on Android you probably have ended up using AsyncTasks to do background tasks and then have a response on the UI Thread. Well, author confesses: "I HATE ASYNCTASKS".

Asynchronous operations in Android are very hard to get right due to the Activity lifecycle. AsyncTasks don't handle any of it making them difficult to use. Loaders handle many things for you, but have a clunky api and fall down anytime you want to do anything more complex than loading data immediately when the Activity or Fragment is shown.

This library builds upon rxjava to handle all these things for you with an easy-to-use api.

android-multithread allows to add a listener to the AsyncTask.

Sexy way to execute async/background tasks on Android

Jul 5, 2014

A Job Queue specifically written for Android to easily schedule jobs (tasks) that run in the background, improving UX and application stability.

Jul 5, 2014

This is a small library to help with running long running tasks without blocking the thread they're started on. Callbacks are made on completion. The role it fills is similar to AsyncTask, except more flexible, and nicer to use.

Standard Java concurrency tools like Futures, Executors, Callables, etc are used.
