There are some annotations that indicate the state of the API. While we are familiar with Alpha, Beta and Stable release, the routines library takes a different approach to define its API stability. Visit here to learn more about Structured Concurrency. In the second blog post I am going to write about this.

Luckily in Android, we don’t need to write our own custom CoroutineScope because Android Jetpack already provides us all the CoroutineScope we need. Using GlobalScope may lead to a memory leak. But in structured concurrency, you are highly discouraged to use GlobalScope. In the above example, I have used GlobalScope for simplicity. And make sure you do not have Deferred object outside of coroutine. If you want to add routnes in your project add the following gradle dependencies: dependencies block then you are writing coroutines with Structured Concurrency. It contains a number of high-level coroutine-enabled primitives. routines is a rich library for coroutines, developed by JetBrains. But Kotlin standard library provides only minimal low-level APIs by which other libraries can utilize Coroutine feature. Coroutines are more like a task that can be executed in any thread.Ĭoroutine is a Kotlin language feature. So a developer can fire and forget a long number of coroutine without any headache. Coroutines are way cheaper than actual Java Thread. Kotlin coroutine is a lightweight thread. Moreover, like a future or promise, it may complete with some result or exception.” It may suspend its execution in one thread and resume in another one.

“A coroutine is an instance of suspendable computation, conceptually similar to a thread, in the sense that it takes a block of code to run and has a similar life-cycle, it is created and started, but it is not bound to any particular thread. Now with a coroutine, we can write asynchronous and non-blocking code as if it was synchronous and blocking code. Before coroutine, we had to write so much boilerplate code to run asynchronous business logic.

By the introduction of Kotlin, now we can be more focused on business logic. Android development with java was full with so much boilerplate code.
