Kotlin coroutines provide an API that enables you to write asynchronous code. With Kotlin coroutines, you can define a CoroutineScope, which helps you to manage when your coroutines should run. Each asynchronous operation runs within a particular scope.
Global scope is used to launch top-level coroutines which are operating on the whole application lifetime and are not cancelled prematurely.
A LifecycleScope is defined for each Lifecycle object. Any coroutine launched in this scope is canceled when the Lifecycle is destroyed.
A ViewModelScope is defined for each ViewModel in your app. Any coroutine launched in this scope is automatically canceled if the ViewModel is cleared. Coroutines are useful here for when you have work that needs to be done only if the ViewModel is active. For example, if you are computing some data for a layout, you should scope the work to the ViewModel so that if the ViewModel is cleared, the work is canceled automatically to avoid consuming resources.

You've significantly simplified the comprehension of coroutine scopes. I truly appreciate it.
I had no chance of understanding Coroutines, but you made it look so simple!
Yay, happy to hear that buddy!
Ok, this is the best explanation of the things that were confusing me. Thank you very much!
Thank you for all the good content!
Very well explained and demonstrated, thank you. 🙌
Loved your explanation style !! Keep up the good work !!
It amazes me how quickly and easily this topic can be explained and shown !!!
Thankyou dear for this easy and understandable explanation 👍
That is my man never disappoint, You are the best
It is amazing! I finally understand what happen when we use lifecyclescope
Thank You , It was very useful.
You are amazing. Thanks for the content.
Yes please do more videos like this!
best explanation ever, thanks too much
Thanks!
Thank you! ❤
Great Explanation, thanks bro
Thank you
The best!
Thank you ...
Very nice
So there is no way to use a LifecycleScope or ViewModelScope inside of an Adapter class?
What is difference between CoroutineScope and GLobalScope about their lifcecycles? when CoroutineScope Cancells autmatically?
Make a detailed video on Coroutine Jobs
what if you created an infinite loop without using "delay" and instead system time difference, I think it will not be cancelled even if the coroutine is tied to the lifecycle.
хорошие видео для понимания
+1 thank you :)
So you mention global scope coroutine will run even fragment A is destroyed but after again come back to fragment A the fragment A will start again right then coroutine will start again..
So we have 2 coroutines or what will happens..?
Will there be a jetpack compose course?
Definitely in the future
I like this... but want to know is there any better content for proffessionals?
When u create video use android studio default theme, it will be very clear for visibility as compare to dracula theme
