Powerful Android Apps CLEAN Refactor

The best android courses on the planet: codingwithmitc...
I did a major refactor to the "Powerful Android Apps with Jetpack Architecture" course.
Here's a high level of what I did:
1. Migrate from Dagger to Hilt.
2. Update Navigation Component.
3. Avoid sharing viewmodels. It makes unit testing easier when I can test fragments in isolation.
4. Splitting business models into Entities and Dto's. This way I have a clear business model, network model, and caching model.
5. Writing use cases.
6. Unidirectional data flow with MVI and kotlin sealed classes. (See Interactors)
7. Refactor message handling system to a Queue.
8. Migrate from Shared Preferences to DataStore.
9. Migrate from Kotlin synthetics to ViewBinding.
10. Write Unit tests for use-cases.

PERFECT - Just Brilliant, I have written an App based on his and the App (only like 500% larger with multiple Modules similar to Blog) was Buggy in every way, NOW after the re-factor, evrything is running perfect - Well needed re-factor thank for all the work you put into it!!

Hi, mitch. I am watching Powerful Android Apps with Jetpack Architecture on your website. you used Job Manager to Cancelling Jobs. after refactoring those classes are completely gone. Is this refactor has that canceling active job functionality?

[@saraha.1336]

Can you do a quick overview of everything you need for android development

[@codingwithmitch]

Ya should only take a minute or two

Hey Mitch, take good care of my engagement 🙏 There you go 😅

I'm securing your engagement and locking it away safely

[@ubersticks]

Did the Powerful Android Apps with Jetpack Architecture course video itself get updated to match this refactoring? It would be fun to retake the course, but only if it were updated.

[@codingwithmitch]

The videos did not get updated. That would be a new course

[@CryptoCodeZone]

@@codingwithmitch I suggest you re-make this app video After the Compose re-Factor, becaus NOTHING will be the same as the original! you re-Factored the 85% back-end part and compose will do the last 15% !!

[@codingwithmitch]

@@CryptoCodeZone Ya it would be a good course for sure

yes i get the ideas XD

I am jealous of clean architecture. Here is your engagement!

[@soulesidibe]

Hey Mitch! Thanks for sharing. This channel is huge. Really like it. I like clean a lot and it's cool you use it. I have a couple of questions for you: Dou you plan to separate the layers in different modules? I found that it's great to do that. You can have a real Kotlin module with no android deps. You can hide the implementation of your data sources and expose only the interfaces using dagger The second question is about your usecases. Do you think is a good idea to make the domain be concerns about the retrofit interface or the dao interfaces event there are all interfaces but they have annotations that came frome third party libraries. What your thoughts on that. Thanks again 🙏🏾👍🏾👌🏾

[@codingwithmitch]

Guess you'll have to watch the course 😉

[@balfit]

Engaged. My 2 cents for easy understanding: FIFO -> pipe, you put in something, falls out the other end; you put in multiple things, they cannot overtake each other LIFO (stack) -> bucket, you have to remove the top item (put in last) to access the next lower one etc

[@HungVu-dm6xc]

I want to use the new add, not replace, mechanism when using the navigation component, what should I do? Add (not replace) fragment with navigation architecture component

[@kasemsm8092]

Nice 🔥

[@bboydarknesz]

So is that mean, I will have some alike this clean architecture in KMM course? And will this refactoring course will have separate course from older one ?

[@codingwithmitch]

Ya exactly the same

[@tekniktdr]

On 28:13, line 106 I think that should be "assert(!emissions[2].isLoading)" Notice the index. Index 1 is the previous data event, and because of that the assertion will be correct (data is not isLoading).

[@codingwithmitch]

No second emission contains both data and loading=false

[@tekniktdr]

@@codingwithmitch Got it. Thanks for the clarification! And for the videos too!

[@justinstevenson4168]

Hey Mitch, please accept my engagement. Also, do you have an idea when we'll start seeing the videos for the next course? Looking forward to it!

[@codingwithmitch]

Not sure. Planning lectures now.

[@jamesblack2719]

I am curious how your refactor will change regarding your view models when you move to Jetpack Compose. You could probably still just do it at a screen level as long as your compositions aren't shared between screens. Nice video though.

[@codingwithmitch]

Ya should be same

Hilt cannot be used for multi feature module

[@codingwithmitch]

Ya it can.

[@siddharthgupta6214]

@@codingwithmitch can we have a video for that please, since I'm unable to find the perfect solution for this. Official documentation is saying to use dagger since only application module can use hilt and we have to use dagger in other modules

[@codingwithmitch]

@@siddharthgupta6214 You set up hilt in the app module then you can declare hilt-modules in the other android modules.

[@pablocruz1302]

Hi mitch, do you plan to re record the course of that application? If you can do that it will be awesome. Everything change a lot in a small amount of time since you publish the course

[@codingwithmitch]

No plans right now to do that

I wonder if you tried the new mongodb realm KMM library? And if is a good alternative for sqldelight?

[@Trecoolerok]

I don't think so. I've seen some articles, where companies used realm and drop it after some time
