Why take this course?

This is the most complete resource online for learning about Kotlin coroutines.

Coroutines are the hot new topic in Kotlin development. They will impact everything you do, and make your applications multithreaded. Efficiency is the main goal, and with this course you will become an expert in designing multi threaded, parallel applications. This is the best resource you will find online to learn about Kotlin coroutines.

This course will take you step by step, through each concept related to coroutines, discuss it in detail, then apply it in a practical project in Kotlin.

We will cover topics such as:

Scope
Context
Suspending functions
Jobs
Dispatchers
async
withContext
Exception handling
Asynchronous flow
Properties
Flow cancellation
Operators
Buffering
Composing flows
Channels
Producer
Pipelines
Fan-in and fan-out
Buffered channels
Ticker channels

We will go through all these topics and explain them in detail. We will also implement many coding examples to make sure you fully understand and are able to apply the concepts.

In addition, we will also be working on several Android apps to apply the knowledge we learned.

A background image processing app
A network communications app using Coroutines, Retrofit and MVVM
A Room database using coroutines
A news ticker app using Asynchronous Flows, Retrofit and MVVM

This course is great if you want to take your multithreading and parallel processing skills to the next level.

Sign up today and let's start learning about Kotlin Coroutines.

Really good course to either fill up the gaps or learn from scratch. It covers really major part of the information you need to know to work with. However, wanted to suggest reducing the part of manual coding and project setups, that just repetitive and takes extra time. Also, maybe it's only my feeling, but I guess it's worth mentioning some more specific real-case scenarios on how particular functionality might be used. Besides, I encountered some extra questions during the course, like what if we have more than 1 consumer in the case of channel buffering, so I'd suggest considering a bit more edge cases for a better understanding of how it all works.

I recently had the privilege of enrolling in the "Complete Kotlin Coroutines development course 2023" course on Udemy, taught by the exceptional instructor Catalin Stefan. As an android developer looking to delve into the world of asynchronous programming in Kotlin, this course was an absolute gem. Thank you Catalin Stefan.

Explained things in a simple, understandable and practical way. I now have a much better understanding of coroutines. Thank you!

Very concise course without exceeding the scope of the material! I liked how simple it was to demonstrate the topic at hand without building an intricately massive project that dilutes the main point of the topic.

Yes...so far so good! Great stuff. I need to repeat the lesson to familiarise myself with some concepts and their interrelatedness.

This course is really great and easy to understand, however in the channel section, it seems like it was just a practice for the documentation, no explanation for real use cases, it could get my 5 stars if it was explaining this part properly.

The course is good, really well explained, and I recommend it a lot to anyone that wants to learn the basics of Coroutines and Flow. However, I would like to suggest an improvement: please use examples that are a bit closer to a real use case. This course, like many others online, try to explain a concept by using the most banal examples possible, for example, asserting that 1+1 = 2. "I create a code that prints Hello after 1 second, and look, in the practical example, the word Hello is printed after 1 second". For me, when the example is that simple, I don't see where to apply the concept and then I don't learn properly because I still have doubts on how to use what I just learned. In this course, using Room and Retrofit were great examples, but for basically the rest of the course, the practical example was exactly the same as the slide used to explain the concept! Please, improve the examples, make them more real. That said, thank you very much for the course!

It was a nice experience. Got to learn a lot of things. But sometimes I feel there should be some more explanation of how the function works. For example in Mutex section tutor could explain things based on induvial coroutine working steps.. But overall it is good!

Great course, very concise and clear! One point that could be added: Some real-case scenarios regarding this topic from experience (maybe some bugs or tips).

The course is good but the projects that students download should ALWAYS be compatible and run on the latest Android studio build. At the time of writing this review, the latest version is Android Studio Electric Eel | 2022.1.1 and the samples downloaded from the course don't work on that Android Studio version.

I was struggling to understand coroutine concepts. It was very confusing but this tutorial is just what I was looking for. Simply awesome

Enjoyed the course but it felt rushed at the end, and there could have been more examples of how to use channels and shared states within Android like sections 4, 5 and 7.

Wrong statement about global variables update. This style may create a race condition in a real application. Very synthetic examples. I prefer either Android or Web Service (backend) examples, without "runBlocking", because I should know how to start a new coroutine in a real world

Learning experience was good, The major topics are covered, But It could have been better to provide example projects are not actually completed properly

The course does do a good job with explaining. My main concern was that it could have included more advanced topics and situations that are encountered in day to day development like parallel, and sequential situations, and best practices to follow when working with real life problems.
