Kotlin Coroutines Beginner Example (Android)

High quality programming courses: codingwithmitch.com/courses
In this video I take you through your first kotlin coroutines example.
If you are complete beginner when it comes to coroutines and want to see what they're all about, this is the video for you.
The main goal of coroutines is to "simplify asynchronous work by getting rid of callbacks." Coroutines are NOT threads. I like to think of coroutines as JOBS. And each "job" may contain "child jobs". Jobs that can run in any thread. Many coroutines can run in a single thread at once.
They're kind of "like" threads because you can start them up and do work asynchronously, but they aren't threads. Many coroutines can exist and be running in a single thread.
The main dispatchers for building coroutines is:
1) Default (CPU intensive work)
2) Main (UI Interactions)
3) IO (Input/output. ex: network or disk transactions)

Coroutines, another strong reason to shift from Java to Kotlin
Thanks for the video

[@codingwithmitch]

Yeah very strong. And this is just the surface of what it can do

[@Sam-si7xv]

Hi, i think im late here, but i need to ask about your statement. So, java cant use coroutines?

[@alexeymurnikov1413]

@@Sam-si7xv nope

[@Monkeydluffy-we2fk]

@nero I don't know y someone will use asynchronous task now instead of loaders or executors🙂

[@KCIsMe]

@Saptarshi Samanta 1 year later, but yeah you can use kotlin with asynctask

[@gilsonjuniorpro]

Finally, an easy way to understand coroutines, thank you, helped me a lot

[@codingwithmitch]

There's a lot more to it. This is a very very brief introduction

[@DivyangM]

A really good way to show an example and finally someone who actually knows the meaning of "beginners". Just recently started learning Kotlin and couldn't understand how coroutines work.
This one is the best explanation possible for that, literally.
Thanks a lot.

[@tanvimandanka2121]

Just love the way he explains everything

[@yasseraltamimi9060]

I watched many tutorials and it was so confusing. your tutorial made it very easy and now I think I can start using it.
Thanks a lot.

[@TiagoDvl]

Thank you! Simple and without long useless speeches!
Amazing work, man.

[@powerlevel8000]

I'm now super excited to browse through all your content, you kept it really simple and explained the concept quite well, thank you! And subscribed.

[@anirudhyeddula3411]

i've been reading several blogs and documentation, but this is just one video that made it look all so simple. thanks for the awesome video. Hope you keep churning out more of them.

[@codingwithmitch]

Always churning brother

[@kharagkunchok]

I always findmy self landing in your channel when ever I searched any issue. Thanks

[@sudhir1274]

This is very useful tutorial on running a "multi threaded" application in Android and Kotlin using Coroutines. Very well explained. This is better than Async and other thread related concepts. Thank you very much for sharing. You have explained in 23 odd minutes a concept I have previously not understood in spite of spending hours on tutorials and other videos. Much appreciated.

[@gilong1311]

Hey Mitch, just tried it myself. Great tutorial, it cleared up my understanding of suspend functions. I was under the impression that delay() would suspend each suspend function and not the entire coroutine. Thanks for clearing that up!

[@ClintPaul89]

Wow. This is like the simplest detailing someone can offer on Coroutines. I implemented it yesterday reading some other blog. I had my doubts still. Now it's all sorted. Thank you.

[@codingwithmitch]

no problem brother

[@cbnewham5633]

Thanks for the very clear explanation - the best short video I've seen on the subject. Everything explained and no magical coding.

[@SolaireOfAstora97]

Actually this is really impressive, you explained Coroutines in a direct and easy way which is probably more complex than understanding Coroutines itself! Great job man!

[@sudhir1274]

As a result of watching this video four times to fully understand the concepts of coroutines, I have successfully run a piece of code which for the past week kept crashing. This also works for normal Kotlin code outside of Android. Once again, thank you for sharing this video and explaining how coroutines work.

[@x32gx]

I read quite a lot about coroutines. This video is top notch at explaining it all. Well done and thank you!

[@ngoquang2708]

Been waiting for this topic for so long. Now I am happy!

[@hritikgupta189]

Thanks for keeping us updated !

[@jesprotech]

I really like this tutorial. Very easy to understand and it cleared up a lot of questions I had. 👍. It really puts in perspective the actual difference between coroutines and threads, which is so important when making reactive and resilient software applications.Thank you!

[@swissmatteo]

I absolutely loved your lesson on Coroutines. Thank you Mitch

[@NomoBuddhay326]

Superb Mitch, your way of explanation is too too... awesome in shot span of time with perfect example. Keep it up i watched all your lectures over android.

[@luisjaviercastroreyes9566]

Thanks for the tutorial, the way you showed how coroutines work is intuitive.
Love your English, it's so clear for non-native English speakers. Thumb up and new subscriber to your channel. Greetings from Mexico.

[@codingwithmitch]

Thanks from Canada 😬. Glad it helped you.

[@paragkadam2169]

This was all I needed to get started with Coroutines. Thank you!

[@tonyalbanese6446]

Thanks for making this video. The task of making sequential requests based on network responses drives me crazy! Thanks for this excellent video. I really appreciate it.

[@nikolatrailovic]

Really good introduction to coroutines. Thanks Mitch! Btw, nice t-shirt :)

[@ahaha233]

You're the best Android teacher. Thanks so much for your videos.

[@pythongabi]

Better than the google tutorials, seeing the coroutines in action is way more simple to understand than abstract explanations. Thanks!

[@asifddlks]

A big thumbs up for making it so simple to understand.
Love from a small developer.

[@Juankokcm]

It's been a while since I watched a tutorial that is not "copy this code and it will work". I fully understand something that I tought it was really messy. Thanks a lot man!

[@hiteshmodhwadia2084]

Explained with a very detailed description. Thanks for the video

[@PaoloValerdi]

Great! Next timer I think it's better to run the coroutines in the lifeCycleScope or scope one to the current activity/fragment or even better the viewModelScope :)

[@maXXik1337]

Me: Simple explanation? 23 minues? Naaah.
Also me 23 minutes later: Well, good job.

[@khaledqwas8851]

Mitch, you are the best teacher of android on TH-cam, keep it up.

[@codingwithmitch]

Thanks pal

[@androiddeveloper1]

Never understood Coroutines much better, thank you for the video.

[@amir123000]

I like the way that you explain ,whenever i got problem in android concept and implementation i check whether you put something about it on TH-cam or not. thank you very much

[@abakasha301]

the best video for a beginner. Thank you Mitch.

[@ivanbartolelli9361]

I've understood everything. This is an excellent video!

[@alaqelabubaker]

Your way of explaining things is very unique, RESPECT.

[@fatemacherif5069]

Thank you so much for this video, Helped a beginner like me a lot!

[@AKispert1965]

First time watching one of your videos. Been working in Kotlin for awhile, but completely new to Coroutines. Nice beginner introduction.
Would be interested in viewing a series on Coroutines, i.e., how to cancel them, etc. Maybe even something on Flow, etc.

[@yasmeenemam]

Thanks a lot this is the most clear and obvious explanation for Coroutines.

[@prashant558908]

Amazing video Mitch, great work.

[@Pinipon.Selvagem]

Thank you for the simple tutorial.
Wanted to replace AsyncTask, since it is now deprecated, and this seems great! It will actually look better than the code i had.

[@carloszetula2307]

Thank you so much for your so didactic explanation about Coroutines. From now on I will be able to use it much better way. Thanks a lot again.

[@daoanhvu4129]

Thank you, I have gotten confused about coroutines until I find this video.

[@sharifurrahaman885]

One of the best video to understand kotlin coroutines

You are awesome and main thing with every video is you zoom the most important part which I liked the most. Also you explain in layman terms where one can easily understand and implement. Thank you so much this video tutorial helped me a lot.

[@rajendraprasadpatil]

Zooming is important. I agree.

[@VickyJunior]

Corutines haveb been confusing to me until today. Thanks a lot.

[@shimonrothschild]

Excellent introduction to Kotlin and coroutines. You need to already understand threading.

[@bYTeHeaD]

Wow, this is indeed very simple to follow.

[@codinginflow]

I don't like how you talk about AsyncTask and SQLiteOpenHelper

[@codingwithmitch]

They're poop

[@pembatamang8233]

​@@codingwithmitch yes they are 💩

[@iamnvn]

@@pembatamang8233 Also now the AsyncTask is deprecated.

[@chibuikeoffu]

Someone is getting offended
