Dagger-Hilt in Detail - Full Course

[@PhilippLackner]

Over time, a few things changed in regards to dagger hilt. I made a new video in which I cover the most up to date things and also some more concepts I didn't cover in this one: kzbin.info/www/bejne/mJOwpKh_Z9VkerM

[@fb767]

Also, note that ApplicationComponent has been replaced with SingletonComponent. ApplicationComponent will now cause a unresolved reference error.

[@vamsireddy7560]

Yes ! ApplicationComponent is Deprecated in new Version of Dagger then we have Instead use SIngletonComponent

[@osmanmusse9432]

thanks

[@yarivzip]

@@vamsireddy7560 but how do you annotate the dependency itself if the class is a singleton and you want it to only exist at activity level?

[@pqsk]

@@yarivzip I believe that's ActivityComponent

[@durbie90]

Please don't ever stop making videos. Every time I watch one of your videos I get an Aha! Moment. Learning so much from you.

[@livlop]

This is really a complete video about Dagger Hilt and very easy to understand, as Philipp started to explain "if you want to inject 2 strings", you can realize that this video is better than others on KZbin and in the same way it has enough fundamentals concepts of Hilt so you can start the implementation in your application. Really thanks Sir 🤜🤛

[@aravindhsamidurai5300]

This is an awesome video to easily understand Hilt. Even Google developers also don't teach like this. Thanks a lot, @Philipp Lackner for making this video.

[@mikemikee7797]

Android file system could be also a good candidate for "in detail" video ^^

[@bjugdbjk]

This video clarified my many questions on Hilt and you have such a great skill of explaining complex things pretty simple way. Thanks again.

[@Mikerandria]

I wish every tutorial on KZbin would be on this level! Too clean.

I was just reading a cheat sheet to get familiar with the annotations, then you upload this awesome video. Thanks!!!

Thanks for brief but complete intro to Hilt.

[@phatho3875]

Nice. What I need is an simple example of DI. And this is exactly what I’m looking for

[@nevermore7755]

For those having trouble with ViewModel log cat: @Module @InstallIn(ActivityRetainedComponent ::class) object MainModule { // This will only live in main activity // Cannot have @singleton that only lives as long as our activity // Instead of @Singleton, we use activity scoped @ActivityRetainedScoped @Provides @Named("String2") // if we need to access context, say strings file, how? // We used context as a parameter!! // dagger hilt will also figure out which testString1 we will inject!! fun provideTestString2(@ApplicationContext context: Context, @Named("String1") testString1: String) = "${context.getString(R.string.string_to_inject)} - $testString1" }

[@dharamveergupta1305]

Perfect ! Your videos the best ones in all youtube bro! Have you got same videos about Koin ?

[@bro_chenzox]

You use a parameter in ViewModel and scope of that parameter is ActivityScoped but has to be not less than ViewModelScoped. Component of InstallIn has to be the respective ViewModelComponent at least.

Hi Philipp, can you make a video about how to read the android developer documentation and learn to help outselves? Love your vids😁

[@PhilippLackner]

Sounds stupid but by just reading it. There is no "right way"

[@amitmondal7427]

I really enjoyed the Dagger-Hilt 💕💕💕

[@mrjackson9137]

One more point about Dagger Hilt is that you are not able to configure it for the library project as the entry point for it always has to be the Application which is absent in the library.

[@hmasaya6409]

すごく参考になりました。ありがとうございます！

[@abdo-ar-888]

Thanks for your amazing tutorials ❤

[@ajinkya_jagadale]

Thank you for explaining hilt in details !!!!

[@mehulbisht9708]

Hey, is providing Glide instance with hilt a good practice too? Because in your spotify clone app you provided an adapter instance as well along with glide instance. Kinda confusing, if I only wanted to pass an arraylist to my adapter but passing the glide instance in the constructor over the adapter now requires me to provide the adapter instance with hilt as well it seems. So what's the best practice , Philipp?

[@PhilippLackner]

you should always make glide a singleton, and therefore provide it. You don't need a provide function for the adapter if you inject stuff in the constructor and hilt knows how to create that stuff

[@codinginflow]

Glide is a singleton by default and it uses the fragment argument to handle cancellation of requests. You should actually not provide it from Dagger but instead call Glide.with() where you need it.

[@PhilippLackner]

that's new to me

[@codinginflow]

@@PhilippLackner Just follow the source code of Glide.with

[@diargegaj7436]

What if im depended on a runtime thing ? E.g On my app I have a number picker. With 1 and 2. If user select 1 I want to Inject X thing, if user select 2 I want to inject Y thing. This X and Y are the same type. Type of Z. So in my viewModel (or whenever this will be used) I want only to `@Inject lateinit var test: Z`.

[@ayoubdev]

Hey phillip can you put details video about supporting multiple screen in 2020 I see a lot of tutorial but none of works thanks for great videos

[@amineayachi335]

how i can create a singleton viewmodel sheard between 2 screens

[@anudeepananth]

Injecting a variable into a ViewModel with Hilt can be done easily with just a Companion Object right? Why do we need Hilt for that...

[@fb767]

I didn't understand one thing: At 6:45 you stated that you can have it live for an Activity (by using ActivityComponent), but how do you tell it which Activity specifically?

[@PhilippLackner]

Just the activity you inject it into

[@hanifalfaqih]

Thank you, it help me to how implement dagger hilt in my project

[@yarivzip]

Hey there. I get an error when trying to run the last thing you explained with the view model. When I replace the @InstallIn(ActivityComponent..) and @ActivityScoped annotations with @IntallIn(SingletoneComponent..) and @Singleton it works. I think it's because the MainModule which provides dependencies at an activity layer relies on the AppModule which provides dependencies at application level (because it's annotated as a singleton). Am I missing something?

[@anudeepananth]

What if the variable string2 was created in the activity in a scenario like from IntentExtras and we need to pass it to the ViewModel without using a ViewModel factory

[@nicolasfelipe1]

the TestViewModel example does not work with lastest hill versions.

[@techmarinar]

Hey man thank you for the great explaining,🤩👍

[@bitwisedevs469]

It would be awesome to explain and show things about scoping, regardless this is a good video coming from plain Dagger 2

[@PhilippLackner]

Thanks a lot and happy cheating :D

[@albertbo2178]

When I try to inject to the activity the viewmodel like this fails to compile for this reason: Classifier 'RoutesListViewModel' does not have a companion object, and thus must be initialized here Anyone knows how to solve this?

[@vikashparajuli]

I am want to create an android library (without Application Class, Activity and Fragment) using Hilt. Can you please help on that?

[@unistern]

nice vid. unfortunately hilt doesnt support DI in kotlin object . or do you know how to?

[@renardsskutels]

Thank you very much for that!

[@PhilippLackner]

You're welcome!

[@c99rahul]

You should use the SingletonComponent, as ApplicationComponent doesn't exist in the new Dagger anymore.

[@AlgeriaHere]

Helpful Videos but i have little suggestion , since we sometimes want to inject an a value like for example 2 strings , we can differenciate between using @Named("") , in one my project i did that also with qualifiers , now if both can do the same job what is the difference between them thank you ?

[@yaboyjz]

very nice video man thank you

[@tunahanbozkurt9516]

You are the best !!!

[@SohailAnsari-ek3oy]

ApplicationComponent is now replaced with SingletonComponent in the new version of hilt.

[@salimmuhammed_um]

for new version use SingletonComponent::class rather than ApplicationComponent::class

Thank you, was looking for this.

Is @Singleton is same as 'object' keyword in Kotlin?

Is there a way to pass "myFragment" to the module? I used to do that in Dagger2 however I have no idea how to do it in Hilt

thanks a lot, but in hilt module ApplicationComponent replaced with SingletonComponent

Your library is nearly complete. It's missing a playlist for Dagger Hilt showing examples of various objects being injected into various logical places.

[@seba23571]

for a strange reason I used hilt version 2.35 and it didn't work for me, then I used hilt version 2.40.5 and it worked, maybe someone has experienced the same thing

[@raghavaggarwal8644]

Hi Philipp thanks for the tutorial, after watching this beginner tutorial, which playlist of yours would u recommend if I want to start practically using Dependency Injection.

[@starlite5097]

Thanks for the video, I will go next to the Spotify clone I think.

[@hojatghasemi8628]

This video needs to be updated because the gradle dependencies that are mentioned are not correct at this time and the dependency for "hilt-lifecycle-viewmodel" isn't needed in the newer versions of the library (if it's added to your project, there will be runtime errors).

[@PhilippLackner]

That's why I pinned a comment with another video 😅

[@hojatghasemi8628]

@@PhilippLackner please remove this video; it's a bit confusing when there are 2 vids but only one of them is correct tutorial and you have to specifically read the comments to realize which one to follow 🤷🏾

love this video. I have a question, what if I'm working with MVP (with Repository Pattern) and want to inject a room db instance and a retrofit instance? Do I need to inject roomdb and retrofit instances in the View, and send them as parameters to the presenter, and from presenter to the repository? thanks philipp for this tutorials, finally applying DI in my projects by watching your videos

[@DjangoMx]

ok, si lo haces como dices estarias rompiendo el patron MVP ya que el framework en este caso android no debe llegar al Presenter, lo que tienes que hacer ahi es hacer una abstraccion de esas dependicias a una interface y usar estas en tu repository una vez que lo hagas al crear el provide del repo creas otra clase que implemente cada una de las interfaces antes mencionada es decir una que implemente la del localDataSource(Room) y otra que implemente el remoteDataSource(Retorfit) en cada una de ellas puedes pasar el context o cualquier otra dependencia que necesites y sera esta implementacion la que le pases al repository.
