[@sumeetrathore3140]

Hi sir its very helpful and understandable video ....i have question what is the use of init method in viewmodel class , is it necessary to use that method for initialization.??

[@CheezyCode]

If you are asking about init block in view model then it is just a Kotlin concept. While creating the object, init block is called - use of it depends on your requirements. During the initialisation of the object if you want to execute some code - you can use init block inside any class.

[@maheshgharage8480]

How can I communicate with you personali for my project

[@sopnilshinde985]

Is it a good idea to pass a Context to ViewModel , since we try to keep things loosely coupled , like view and viewModel should be loosely coupled , if you pass context of view to View model , I am bit curious about this

[@CheezyCode]

Depends on how you use it. Context is needed in this case. We should pass Application Context. Passing context as an input is always preferable to have testable class. You can easily write the test cases.

Thank you !!

[@umangsharma113]

What if I wanna have more than one constructor for Mainview model class ?Do I need two factories?

[@CheezyCode]

This is simply factory pattern implementation. Generally fixed number of parameters are expected. So having secondary constructor in ViewModel does not make sense.

[@InnovativeChangazi]

Awesome series.

Hi sir, Thank you 🙌 Want to know can we use MainViewModel with different activities Here, I created a QuoteListActivity and I want to show list of quote in recyclerview and onItemClick of item open QuoteActivity which show single quote My question is If I user same MainViewModel with different activities is right choice or is there another way to achive this scenario?

[@CheezyCode]

You can use same ViewModel with different activities.

[@riyabaranwal6267]

can anybody help , actually I am a beginner and going to 3rd year . I started this android development journey with one udemy course of 'Denis Panjuta' but when I was learning MVVM I was having issue as he didn't make us understand in deep therefore I am here but when watching this video I was lost since , for eg- in this video sir went in the res or the layout folder to change the color or define the icons but according to Denis sir ,I use to do it in the main activity only , even I was defining every single detail of button , icons , and many more in a different way . This question might seem silly but please if possible help me , I am unable to understand , wht's happening , I am feeling like giving up

[@CheezyCode]

Give some time... everything will make sense...just follow it..

Thank you sir

[@MrRahulmalik]

We could have used AndroidViewModel to get application context and no need to make a view model factory

[@CheezyCode]

Yes. But AndroidViewModels are not easy to unit test. It's better to use ViewModel instead. There is always a debate on when to use what but most of the developers have suggested to go for ViewModels

[@ArsalanKazmi007]

If we are on index 0 and then we press previous. The index shall decrement to -1 and we can get a NullPointerException? We need to handle that too here ,Right?

[@CheezyCode]

Yes
