Suggestion:- All the videos about coroutines on RU-vid are uploaded a year or more back. And none of them explain such clearly with such examples. It's getting very easy for me to catch the topic. All I can say is THANK YOU 🖤🖤🖤. Spend some money to make the content reach more people.

Sir, just a humble request please make a complete series on WorkManager, Services and BroadcastReceivers together explain their uses and their relations between them. Bundle of thanks to you. Stay blessed! Others please if agree hit like to escalate the need of this series.

I am quite amazed how someone could explain one of the difficult topic of android in such a beautiful way that it seems very easy.

Completed the entire playlist today and i think you create by far the most simplest explanation videos for Coroutines. I mean i do follow a couple of RU-vid Channels for android dev but trust me when i say this, you just seem to make every hard topic easy to understand as well as implement. I pray to God that you're channel becomes the most popular resource for Android Development. And you keep on growing and making more and more awesome videos. Cheers :)🥳

@simranaggarwal9352 8 месяцев назад

Why the output is "1- DefaultDispatcher-worker-1" in case of Global scope when IO Dispatcher is used? Going by the output, it looks as if the Default dispatcher was used. Am I missing anything?

@CheezyCode 8 месяцев назад

coroutines launched with Dispatchers .IO are executed on a pool of threads named "DefaultDispatcher-worker-X' Same for Dispatcher.Default

@googlysahoo1397 2 года назад

How to know when to use CoroutineScope, globalscope and mainscope, also dispatcher.IO, dispatcher.main & dispatcher.default?

@CheezyCode 2 года назад

Coroutine Scope for Android - not required as we have component specific Scopes i.e. ViewModelScope, LifeCycleScope GlobalScope can be used if you want application level scope for your coroutines. For Android it is not recommended. For testing purposes you can use. MainScope is fine but use LifeCycleScope instead. Dispatchers.IO - when you want to do IO Operations. Dispatchers.Main - want to execute something on Main Thread. (UI Update in Android) Dispatchers.Default is for nomal computation. Hope this helps.

@arjunkataksh 2 года назад

I am not able to understand what is the difference between Dispatchers and Coroutine Context ?

@CheezyCode 2 года назад

- Coroutines are run inside Coroutine Context - Context majorly tells you 2 things - Dispatchers + Job - That means, Coroutine Context includes Dispatcher and Job Element. - Dispatcher defines the thread, Job provides you handle to the coroutine. In simple words - jo mind mei baitha rkha hai - Context aapka Thread pool define karta hai jispe aapke coroutines run honge. Predefined thread pools hai jinko dispatchers bol rahe h. Dispatchers.IO, Dispatchers.Main etc. Baaki Job important concept hai - coroutines ko handle karne ke liye. Hope this helps.
