Man, first of all, you are THE BEST Android UKposts channel in the whole website. Second, you are just awesome!! You are a great teacher and a very charismatic human being. Last, but not least, I don't know how you don't get tired of making so many great videos. You ARE the best!! Thanks for teaching me so much. It's being a pleasure to have your videos as part of my life.

This is by far the best explanation of Dagger Hilt I have found online. Not even the official Android Developers' UKposts channels explain it like you do. Thank you so much!!

@alexeysimchenko7494 Рік тому

I use dagger/hilt every day but usually as copy/paste so today I decided to finally get known how it works. Your explanation is the best of several that I saw today!

@moforemmanuel158 Рік тому

your tutorials are the best because you take time to explain the subtle concepts behind the code which is rare from other tutorials i just had to watch this once the get the whole scope of what DI with Hilt is and it implementations

This is about a tool / library. Tools and libraries will change over time. Most of the things you learn in school won't change. If you are in engineering school you are not there to learn how to make a hole in metal with one particular kind of machine. You don't need a professor fot that. You are there to know why, when and where you have to make that hole.

I normally blast through these tutorials but this one took a solid 1-2 hours because of coding and note-taking at the same time and there was so much good content. For example it takes 7 individual scrolls to get through the notes top to bottom, that's a lot more than usual

A very frequently my class functionality requires the context. But it is available only in an activity. So I was really frustrated until watched you video. Now, I just tell - inject! That's it, simple and elegant.

@RahulKumar-un6ur Рік тому

Wow....what an amazing,clear and short to the point explanation. Out of curiosity, I would like to ask a question please. Can we keep the AppModule a normal class instead of object? Is it recommend to make a module (of course, not a binding module) object instead of a normal class? I tested and both works. Tons of thanks for your time and this amazing explanation.

@mithilmehta1501 Рік тому

@@mithilmehta1501 No, no its just an example. Let me give you the example. ----------------------------------------------------- class Customer @Inject constructor(@CName val customerName: String, private val age: Int) { fun printCustomerDetails() { println("$TAG :: $customerName is $age old") } } @Module @InstallIn(SingletonComponent::class) object AppModule { @Provides @Singleton @CName fun provideCustomerName() = "Mithil Mehta" @Provides @Singleton fun provideCustomerAge() = 24 } @Qualifier @Retention(AnnotationRetention.BINARY) annotation class CName @Inject lateinit var customer: Customer customer.printCustomerDetails() ----------------------------------------- Here in the module I am providing CustomerName and CustomerAge statically. Not dynamically. I just want to learn how can I do that.

@mithilmehta1501 Рік тому

@@RaajKanchan bro, you are getting it wrong. This is not something to be passed usong dagger. This data which should be passed either from activity to another Activity or else load from network for that particular screen. Dagger should be used to inject those dependencies which screen requires but doesn't care how it is created. So, as per my understanding your usecase is incorrect.
