Kotlin Coroutines: Introduction

Kotlin Coroutines is an async task library for Kotlin language. It makes asynchronous code easier to write and read.

Kotlin Coroutines is an async task library for Kotlin language. It was announced during KotlinConf 2017. Coroutines make asynchronous code easier to write and read. 🚀

It aims to prevent blockages caused by running tasks. This applies mostly to networking code where a task takes multiple seconds at least to complete. kotlinx.coroutines 1.0 is the library you need to import to use Coroutines. You can only use it within Kotlin projects, so if you’re developing your apps with Java, you can’t use it. ♻️

Kotlin Coroutines Features 💫

Coroutines has 4️⃣ main features:

• Lightweight: Multiple Coroutines can run on a single thread. Since a coroutine doesn’t block the thread it’s running on, you can run multiple Asynchronous tasks, which helps you save memory.
• Built-In Cancellation Support: You can easily cancel a running coroutine.
• Fewer Memory Leaks: When you cancel the scope of a coroutine, all coroutines under the same scope gets cancelled.
• Jetpack Integration: Lots of Jetpack libraries support the coroutines…
