ViewModels & Configuration Changes - Android Basics 2023

Is Google making all this unnecessarily complex? Newbie here

i wrote val viewModel by viewModel<MyViewModel> and tried to get rid of error message for 3 hours. i have dealt with this before, but had simply forgotten so i looked somewhere else for mistakes. i'm beginner 4 weeks in

You're making me learn compose in a mere couple of weeks. Why is noone else coming up with these essential videos? These solutions are so simple yet noone will mention them in a documentation

Ich habe gehört, dass Du ein Händchen dafür hast AndroidStudio super gut zu erklären. Aber warum auf englisch? Gibt’s da nicht schon jede Menge guter Video s? Ich deutsch dagegen sieht’s da schon viel schlimmer aus. Warum also nicht auf deutsch?? Die AutoÜbersetzung ist viel zu schnell und auch nicht immer genau.
Vielen Dank fürs Verständnis.

Is this telling us we need to use ViewModel or just what it can be used for if we want to use it? Is it the only way to handle configuration changes or is it an alternative to APIs like rememberSaveable?

Can you make a video of the internal mechanism of how view model works in android. This in my experience has been a recurring question in android interviews.
- Why do we need to extend the ViewModel base class in android
- How view model survives when an activity is destroyed?
And not just view models, but most interviewers tend to ask the under the hood workings of most things in android. This would really help folks not just learn how to use these things, but to understand them and better prepare for interviews as well.

Hey! can you share your green wallpaper?

Perfect as usual, Philipp! I wish you a lot more subscribers! Keep sharing your knowledge please in a clear and understandable way! Danke😉

waiting for 123K

You're the goat i was having difficult in state management and your video clarify my mind, thanks

Can you please explain the reason of getting dublicate class error? thanks

You are great! I learn so much from you and still improving myself. I have a small request from you, Please create a playlist/single video for MVVM architecture with Retrofit API call. Also please make this with Activity & XML (don't use Jetpack Compose).

This man is soon to become the God of native android apps 🙂 Amazing content and best in the world

a big thanks to all your efforts one day i will surely become a great android developer only because of you ❤

thanks for great content 🙏🙏❤ ,

What emulator do you use?

I just want to thank you, I am learning a lot from your videos! Cheers!

Thx for this great video.

Hi sir, thanks for your helpful series. But I got one more question about the differences between MVP and MVVM, can you help me figure it out. Thankyou

Android's ViewModel is not a VM from MVVM. It's just a container which allow to survive configuration changes.
Here is also what documentation stated: "The ViewModel class is a business logic or screen level state holder. " ... just a holder.
I can implement MVP in my app and use ViewModel as a container for a Presenter in order to survive configuration changes.

sehr schön 👍aka very nice

It's a very clear and detailed explanation as usual. Thank you!

Thanks, you explain kotlin compose very well. There is little information at an advanced level in the Russian-speaking segment.

Hi, I never know how to import viewModel. Using by viewmodels() is the newest way? What os the best way to use viewModel with XML. Do you have tutorials?

Great series! Maybe you could include things like - this could be asked in an android interview and share some trick questions :)

i don't understand why not to make UI actions update the model itself and vice versa.

Should we use only one viewModel in whole app or create different viewModels for different purposes?

Hello, can you make a wideo with istalation of Android studio and show how to config it, and what emulator you use ?

Hi Philipp, Can You Also Make a Video About Repository And Data Classes? Would Be very Helpful

if model layer is exposing a list of objects with epoch time, is it good to convert all of them to new object by parsing them to corresponding strings?.. If I follow this approach, I would have 4 data classes that represents the same data: dto, entity, model that repository exposes and model that is parsed for the view. Should I follow this approach?

Videos like this are necessary for developers in any level, some times you need to know how a component really works and what its purpose is, in order to avoid bugs, performance issues and leaks.

Thank you Philipp for all your work. You are really an inspiration for me as Android Developer and I've learned so much thanks to you 😊

Perfect explanation, thanks Philipp

thx a lot for this basics video!

❤ good one

I really liked that you explained in such great detail. When you don't use Dagger-Hilt, everything becomes clearer despite the boilerplate code. I had a lot of memory leak issues with Context 🎉

Please make a video on how to make usecases for a complex app having many features
This series is gonna be very useful

Very clearly explained. Thank you very much

Congratulations Philipp. A simple question, can I work with WorkManager inside the ViewModel class?

It's a cool explanation of MVVM, but what a pity I don't have enough money to buy your premium courses...

cool bro

The thumbnail is great 👍🏻👍🏻

Thank you bro...was waiting on this to start using KMM...will this work for compose ios if I share the ui and the logics ?

The GOAT ♥

👌👌
