I found 3 best KZbin channel for android developers, No.1 coding with Mitch No.2 Android devs No.3 coding with flow And reso coder is deprecated

[@ChrisAthanas]

Philip Lackner is also quite good

4. Phillip Lackner is also very good. He always tells Advance concept of Android.

Thank you so much my man.. This video literally got my back today.

Btw you can do CTRL + ALT + L to format your code and CRTL + ALT + O to optimize imports (remove all unused imports)

thank you very much this one helped me on project and solved my one of annoying issues i was having constructor injection with fragments... had no idea it does not work out of the box to support constructor injection in fragments... i have basics of mvvm coroutines .. and can you help me which paid project i learn from you ..atleast i get the confidence

[@sourabhpal4717]

Nice one. Can we use constructor injection to inject viewmodel in the same fragment?

[@abhisheksaxena518]

After going through some stackoverflow answers and issue trackers, if you have to setup actionbar with navcontroller then FragmentContainerView will not be able to find the associated NavController. In order to resolve this issue, simply replace it with and find the controller traditionally like navController = findNavController(R.id.default_navHost_fragment) Bug Report: issuetracker.google.com/issues/142847973

[@kravgenko2]

Hello, how I can transfer the realization of interface class into hilt in my ViewModel. I can't use @Binds, because after creating ViewModel I should fulfil some method to calculate the required realization of this interface.

[@DerCheckerzeigts]

How to do this with bottom navigation?

[@Murad3223]

wait, where are the videos about the rest of the app, where you build room repo and retrofit?

[@moustafaessam1463]

What if we inject the factory into a method then set the fragment factory inside it? @Inject fun setFactory(factory: CustomFactory) { supportFragmentManager.fragmentFactory = factory } Since the injection is done before the call to super.onCreate() Please correct me if I’m wrong

[@paulaalejandradiazsilva2333]

Do you have any video of deploying Django to Elastic beanstalk? I know my question has nothing to do with this video, but I haven't found a good tutorial...

[@SpaceTimeBeing_]

How to use viewBinding with such a fragment? Since it directly takes in the layout

[@devanshu_on_youtube]

I suggest creating an abstract base class for a view-binding fragment that uses the usual Fragment() empty constructor and inflate the view using DataBindingUtil in the onCreateView method. You can still provide the layout as a dependency in the constructor of this base class, and have full control over whether you choose to use the helpful Fragment constructor with the layooutId or use DataBindingUtil instead. Hope that helps :)

[@harshar6897]

Is it possible to constructor inject view model like this?

[@gagandeepsinghwalia4462]

According to 9:48 one factory will handle all fragments or one factory for each fragment

[@JohnDoe-wx3zm]

Mitch, is constructor injection that big of a deal? The whole FragmentFactory thing seems like a lot of boilerplate, especially when you can just field inject (I know filed injection is supposed to be bad, but does the FragmentFactory have any tangible upsides?)

[@LogicPhalanx]

How is the injection working in your NavHostFragment if you're using the value in onAttach? onAttach comes before onCreate in the lifecycle of the Fragment. When does Hilt do injection in the Fragment lifecycle?

[@codingwithmitch]

In on attach for fragments. Same as with dagger.

[@mohitbalani7956]

I have not learnt dagger 2 can i directly use hilt ?

[@codingwithmitch]

yes

Is there a difference between ApplicationComponent::class and SingletonComponent::class?

[@vasiliychernov2123]

They're the same thing, ApplicationComponent just got renamed to SingletonComponent.

[@prabhattiwari3254]

why you are using fragment factory here?

[@mehranj73]

But it doesn't work with BottomNavController

[@DerCheckerzeigts]

So every fragment needs it own fragmentfactory? So if I have 18 Fragments, I also need 18 fragmentfactories?

[@trampflips101]

One fragment factory can be a factory for multiple different fragments, so no

[@DerCheckerzeigts]

@@trampflips101 But can I have multiple Fragmen factories?

[@trampflips101]

@@DerCheckerzeigts of course :)

[@DerCheckerzeigts]

@@trampflips101 But how? I've tried using "childFragmentmanager.fragmentfactory" multiple times but that didn't work. Please tell me how to assign multiple fragmentfactories to one navhostfragment aka childFragmentmanager

[@trampflips101]

@@DerCheckerzeigts oh i'm not sure about that, I thought you were asking whether you can have separate factories for separate fragments.

nice engagement

[@hashemmousavi2451]

Having Fragment with non default constructor that contains parameters is totally wrong. Because when the Activity killed by system and after coming back to the app, system can't recreate the fragment

[@vasiliychernov2123]

That's the reason they introduced FragmentFactory, you provide your own factory which knows how to create your Fragment with non-default constructor.
