The new dispatcher views API lets you limit parallelism without creating additional thread pools and provides a unified way to create dispatchers for unbound parallelism.Support for the new Kotlin/Native memory manager makes multithreaded coroutines for Kotlin/Native available out of the box.A new API and multiplatform support for kotlinx-coroutines-test introduce a common solution for writing portable tests with suspending functions.Setup - Include dependencies in build.Following the release of Kotlin 1.6.0, the 1.6.0 version of the routines library is out. Kotlin’s concept of suspending function provides a safer and less error-prone abstraction for asynchronous operations than futures and promises. Kotlin, as a language, provides only minimal low-level APIs in its standard library to enable various other libraries to utilize coroutines. It contains a number of high-level coroutine-enabled primitives that this guide covers, including launch, async and others. routines is a rich library for coroutines developed by JetBrains. Small objects will be distributed in single threaded environment, which is not blocking main thread.Ability to wait patiently- tasks executes sequentially and coroutines can wait for the result.Index for current state- you can manage, suspend and resume the current execution.State machine object that means data is available for each state.

Coroutines are like light-weight threads.People love RxJava but is it really worth it? Of course its a great library but using bazooka to kill an ant it’s not. Good for handling streams but how about sequential code?.Forces us to have callback at some time to handle results.Callback hell- Call backs are hard to handle exceptions, read & understand, and debug the code.Each type has it’s pros and cons, If we consider generic problem between all of them are, Java-Thread, Thread Pools, AsyncTasks, Loaders, Executors, Handlers, Future, Service to handle in background and RxJava. Till date there are so many ways to handle the thread in Android.
