What is Android Promise
A library for modular asynchronous calls.
android-multithread allows to add a listener to the AsyncTask. http://snowdream.github.io/android-multithread
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.
