The explanation with the construction workers was genius 👌

[@PhilippLackner]

Thanks mate 💪

Waiting from yours, bro..

I was thinking the same Florian

[@kuriyer_tashkent]

good

Rarely have I commented on a video, but this video is awesome

[@unnibabu]

The best video about Coroutine online! No begging for likes or subscribers, just pure knowledge!!... Thank you

The explanation with the construction workers was easy to understand, Thanks!

Thank you so much for your comment ❤️

WONDERFUL explanation about coroutine!!!
I was learning the Google Android tutorial about coroutine, but it was very unclear and hard to understand.
Luckily I found this video. It was really detailed and clear.
Thank you, Phillip!😄

[@PhilippLackner]

Glad it was helpful!

[@mattgraves3709]

Returning customer, I love when I find a channel that I can use for a good reference and brother I am flying through this app build thanks to you!!

[@hannanshaikh2616]

Awesome, I shifted my development completely to kotlin by following your video, please create more videos on projects

[@nrg4285]

Philipp, consider yourself lucky that you don't code in React Native professionally. Android is so nice I can literally go on 3 year old video and the content is not outdated (except for some config). I can reliably follow this tutorial and it will work no problem. I could not imagine following a 3 year old React Native tutorial, article, or StackOverflow issue and it still being relevant or working. I'm jealous.

[@iamanegi]

Thank you brother!🤗
I was searching for the coroutines tutorial from a long time. Thank you very much.

[@PhilippLackner]

No problem 👍

[@mattgraves3709]

Excellent video and I will echo Florian and say the analogy was great.
I enjoy both of your channels and that is one thing that you share that is essential in making the material stick.

[@manjunathsharma1053]

Best way of explanation with simple example. Thank you.
Just to cross verify,
1. application opens
2. Execute the sequence of coroutine within Global scope.
3. Hit back from activity.
4. Come back to application globalscope coroutine is not launching the sequence again till I quit the app.
Is this correct? If yes it means globalscope coroutines will run only once within activity scope? Please clarify

[@montuedge]

Example was quite good

[@NicolasBeltrami]

Are you gonna do a video with Coroutines + Firestore ?

[@PhilippLackner]

First, I explain the general functionality of coroutines in some videos, what I do after that I don't know yet. But if some people request it, I will also show coroutines in a practical example

[@jjhoninatan55sabadi]

@@PhilippLackner thank you !! I will continue to watch your videos. Great job.

[@shawngardner261]

Is there a good approach of using coroutines for reading files. For example, I have an Android Java app that must read and parse this fairly large CSV file at startup. Doing this on the main thread is not a good idea since it affects the UI performance. So I use threads, but is there better way in Kotlin using coroutines, or just port the thread code over to Kotlin? Thanks!

[@devopsshiv3842]

In Coroutine why i have used GlobalScope() when i fetched data from API using Retrofit? Instead of GlobalScope() if i used different methods then what will happened?

[@abondutta]

if i run a corutine for a long time, then the screen stays blank for long time. if i can show the screen as circular loading then it will be great.
Ex: when doing a http request, if i can show a loader dialog then the user will know process is running

[@alfietapping4034]

4:10 my understanding is that the coroutine shouldn't run, as the main thread reaches the Log before the coroutine even starts, which should cancel all coroutines in the thread, could you tell me what im missing with this?

[@PhilippLackner]

Why would reaching the log statement cancel the coroutines? The main thread doesn't finish just because onCreate is finished

[@alfietapping4034]

​@@PhilippLacknerI was testing this in intelliJ and the coroutine never launches so i guess I was just confusing myself
fun main(args: Array) {
GlobalScope.launch {
delay(2000L)
print("coroutine finishing
")
}
print("Thread finishing")
}

[@kevinsolanki6232]

😌😌😌

[@andyal868]

Sir, what is ?
val TAG = "MainActivity"

[@weeraphongsombatboon9568]

the TAG is the first value we insert into Log.d() . The value is just a String "MainActivity"

[@smonkey001]

5:43 I will say "by swiping away the app, we killed the whole application process, so all its threads and their coroutines got killed".

[@user-bk5il2fy1h]

i think the same coroutine get killed because of killing the app, global scope pointing to app lifecycle, not the main thread

[@smonkey001]

@@user-bk5il2fy1h You're right. app lifecycle is the Android term of application process.

[@mohameddarwish1347]

Sir; how can I use coroutines with a real api and receive data , how can I do it?

[@PhilippLackner]

I will probably show some practical examples of coroutines after the more theoretical part, but not about real api, rather in general about Retrofit/Firestore or similar stufd

[@mohameddarwish1347]

@@PhilippLackner
Is retrofit a coroutines? I am confused about it

[@PhilippLackner]

@@mohameddarwish1347 no Retrofit is a library to get data remotely, coroutines can help do implement that in a good way

Thanks 😊
I'm looking forward to your next video 😊

@@mohameddarwish1347 thanks!

[@djfahed3002]

Actually delaying a coroutine is the not the same thing as pausing it. I think there is no direct way to pause a coroutine.

[@TRUTHF0RCE]

The current docs only add the dependency:
implementation("org.jetbrains.kotlinx:kotlinx-coroutines-android:1.3.9")
Is it correct? Or I need the "...corotines-core"?
