The ViewModel & LiveData Tutorial in Android Studio (Kotlin)

In this video I'll be creating avery easy increment app using a viewmodel with livedata, and this should cover the very basics and give you a general understanding on how you can use a viewmodel along with livedata.
def lifecycle_version = "2.2.0"
// ViewModel
implementation "androidx.lifecycle:lifecycle-viewmodel-ktx:$lifecycle_version"
// LiveData
implementation "androidx.lifecycle:lifecycle-livedata-ktx:$lifecycle_version"

Simplest way to explain it Don't get discouraged by less views bro Your tutorials are easy to learn and very helpful

[@youshaarif4253]

This is exactly what I was looking for. Simple, concise and to the point

[@karateswe]

Simple. And very powerful. One good and simple example is worth more than 1 billion words!

[@Indently]

Hey karateswe, I really appreciate the kind words. Hope to see you around the channel more often!

[@palaksdarji]

One possible change. Its better to put that business logic where you increment the number in the viewModel. Its not View's job to work on logic. It just has to call viewModel's method to update the count.

[@knalliebar]

I have to say, when teaching about the use of viewmodel and why, this is by far one of the most important things. This validates a redo in my opinion.

[@lifeOfCharlesMaina]

Bro ...this is the best explanation I have come around... please make more tutorials such as this...

[@VIKASROYv]

Wow man loved it, you made it very simple.

[@jatinvashisht4293]

best explanation I have seen ever. Great work

[@AwesomeDevNotes]

I can see the future when you do Dagger Hilt, MVVM, Testing, Coroutines, Retrofit, Room, WorkManager, Navigation in one app! It's coming together 🧘

[@Indently]

Eventually I'm sure we will get there. But that sounds like it's going to require a major amount of planning aha

[@kirwakelvinkering3122]

Woww ,this tutorial made things simple for me .thank you .

[@potavios]

Simple and well explained, thank you

[@f.uckeng]

just the best bro

[@farnadtohidkhah9448]

Hi, Thanks for useful video regarding The ViewModel & LiveData Tutorial in Android Studio (Kotlin). I saw in the video that without defining the Button in the activity (like val btn_button=this.findViewById(R.id.btn_button) as Button) you were using directly the button id of the layout. How you did that because Android Studio gets error of this syntax

[@fser2987]

Hi, probably used plugins which is id "kotlin-android-extensions". you can add in grandle file this extensions

[@lixoten344]

Did you ever figured out how he did it? lol

[@iftak01]

Amazing video bud, thanks

[@darwingsanchez5328]

Dude, I loved this video, help me a lot, I have a question, I just want to do the same thing but I want it increment the number itself like automatically. I tried to put the fun in a for and even in a do, while but didn't work... Do u understand? Thanks brother. You're amazing

[@Indently]

I'm happy you like, I think you should look into flows since that the most modern way of doing what it sounds like you're trying to do.

[@darwingsanchez5328]

@@Indently Yeah, I have been looking for flows, thank you man

[@chriscampbell5901]

Great vid, thanks!

[@hilaltube4693]

Very good but getting an error cannot create an instance of class ViewModel

[@chewataapp7021]

My hero!

[@cybergorilla]

Well said, bro! Great job! :В

[@vladyslav.kushnir]

Hi, bro!

[@vladyslav.kushnir]

Where are you from?

[@SertuncSELEN]

you are very nice talking

[@monik1070]

You showed really great tutorial , but I have a question , how did you use TextView and button without even initialising them , please let me know

[@Indently]

Kotlin synthetics

[@rupeshmandal1]

Hello sir, can we make video player app like MxPlayer. Show video folder by folder in recyclerView. Please♥️

[@lyawileh.a8741]

Cool.

[@StarkIndustries2008]

How to remove the observer ?

[@nihadildarov]

Thanks

[@SrichakradharReddyNagireddy]

So, if I don't use an observer on the view model and just do setText on the textview in the button click listener, will the textview get reset after rotation?

[@kamilboryczka7117]

Maybe you will record something about a Room with multiple tables?

[@Indently]

Hopefully in the near future!

[@sarrieri]

Hello kind people, I have a stupid question, I was following this tutorial with the exception of defining my dependencies in the gradle script but somehow the project still works. Same goes for RecyclerView. Can somebody help me understand ?

[@hanguyenxuan2843]

observer was deleted in new update .

[@lixoten344]

Well, did not work for me. i checked and checked..... Someone below asked you....am I am wondering the same "I saw in the video that without defining the Button in the activity (like val btn_button=this.findViewById(R.id.btn_button) as Button) you were using directly the button id of the layout. How you did that because Android Studio gets error of this syntax"
