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.

A utility library for Android to schedule one-time or periodic jobs while your app is running. Currently, Android OS supports 3 types of scheduling APIs: Handler, AlarmManager and JobScheduler.

RxTasks is a lightweight wrapper for the GMS Tasks API, more commonly recognized when using asynchronous results from Firebase requests.

Typically the Tasks API would allow you to add listeners that may be scoped to an activity or executor, however this is not needed since scheduling and Disposable's are handled by the user.

Please note that this library uses RxJava2 so calls must respect Completable and Single chains.
