What is the best way to capture the progress of file upload and download using Retrofit with kotlin I have two different codes 1. I created a request extended class and performing update and getting callback in interface 2. I created extension function with request body and collecting it in flow by calculating the file size and content delivered But in both cases I have to write a lot and I need one plug and play solution, by above i created a function and calling it from many places Any recommendations?

Is buildSrc is the recommended approach to create custom gradle plugins and scripts for Android projects?

Does anybody has a good blog around in memory (not db) state management for list items, add, update, delete) If I want to update an item in the list without mutating the objects. Like I don't want to use

var

Pure Kotlin

Hey I want to remove text from string for example

val string = "Hey 123"

or

val string = "Hey How are you 123"

and output

string = 123

Still trying to think of an android question that's Kotlin-specific enough for this channel.

I have situation here , Live data Observer is set on database object to collect some stack of cards , These stack of cards is shown sequentially to user for every 2 minutes . once this card is shown , I will have to update database to modify its status . but you know how the live data work with room, every time you make update specific row, live data will retrigger (you can read here) , that will call whole flow once again which needs to be avoided To avoid this re-triggering , I made some modification, I will collect cards at the initial, and soon after that I will remove observer My code looks as below

observer = Observer<Resource<List<DisplayCard>>> {
    when (it.status) {
        Status.SUCCESS -> {
            // setting list to emit card for every 2 minutes once
            ambientDisplayViewModel.setListOfCards(it.data ?: emptyList())
            // removing observer
            ambientDisplayViewModel.ambientCardList.removeObservers(viewLifecycleOwner)
        }
        Status.LOADING -> {
        }

        Status.ERROR -> {
            ambientDisplayViewModel.refresh(DataSource(loadFromNetwork = false))
        }
    }

}

With above code , I have received review comments from my peer as below "Viewmodel callback should come to activity/fragment only when there's an intention to update the view." , Do you agree on this quote ? Do you think that I shouldn't keep callback when I am not making any UI

hi guys: Can anyone explain to me why it outputs like this?

Hey guys. How do ensure an edit text only accepts alphabets and digits? I.e A-Z,a-z,0-9 only

I don't feel too comfortable to put up a bunch of dependencies in the application's component when the workers might be already finished and the app might be running... so having a scope for it would maybe make sense? Or maybe use it's service's scope?

Hi there. We'd specced this app to use on-device barcode scan when starting the process, but it appears MLKit by google still tries to send analytics despite being given lots of configuration params telling it not to. Does anyone use that library and know how to actually configure it to stop phoning home? (Compliance reasons, not just personal preferences here).

Hi there , what is difference between object and companion object in singleton pattern ? and what's good way ? , Do both methods have no problem when using? !!!

How often do you use livetemplates? I am a new android dev with ADHD and just discovered live templates. They make my life much easier, for example I have shortcuts for generating recyclerview adapter/viewholder/implementation boilerplate code. In that way I am able to focus on implementation, and do my coding like building blocks, rather than memorizing every detail of implementation. Also I don't need to go to stackoverflow and copypaste basic things multiple times. Even for example during live coding interview having livetemplates seems awesome, copypasting from stackoverflow would be shameful (I think). Using my own custom shortcuts for livetemplates seems the best way for how my brain functions (I suck at memorizing tiny details, but I remember general idea/flow of a pattern and I would prefer memorizing what to use and when to use, instead of all small details of implementation). Is getting to dependent on livetemplates a good practice to get used to? Do other developers frown upon a dev who has dozens of livetemplates and relies on them instead of writing all code from memory by hand?

Hey I am getting error on my unit test.

Hi Guys! My name is Arilson and I’m a teacher and Android developer. I hope to learn and help here!

Is there an idiomatic way to expose state from a Service to the UI? My use case is in a live streaming app with some complex, stateful, and tightly coupled signalling running in a Service. Some of this state needs to be exposed to the user. However, attempting to do so (e.g. through a ViewModel) leads to a lot of boilerplate, mapping Flows and such, and duplicating default/initial state. Any advice?

Looking here: https://developer.android.com/guide/fragments/communicate

class ListFragment : Fragment() {
    // Using the activityViewModels() Kotlin property delegate from the
    // fragment-ktx artifact to retrieve the ViewModel in the activity scope
    private val viewModel: ItemViewModel by activityViewModels()

wtf is

activityViewModels

?

How do I actually add the repository I need for this?

> Could not find androidx.fragment.fragment-ktx:1.3.2:.
     Required by:
         project :app

This doesn't make any sense: https://developer.android.com/studio/build/dependencies#google-maven

Posting here because I think this is not really compose related, and so maybe someone has an idea here. tldr, updated to the new androidx releases today and now we cant build due to this error.

I've tried the new way to construct the viewmodels in activities according to the [docs](https://developer.android.com/jetpack/androidx/releases/lifecycle#lifecycle-viewmodel-compose-2.5.0-alpha01), it feels good. But I didn't find a way to provide the

defaultViewModelCreationExtras

in compose, did I miss something?

Hi guys, can someone help me out, my app is in review since last 8 days, and i mailed them and talked with Google support but still no solution I got, is there anything which I am doing wrong or it is from their end

Hello Guys, anybody know how to write UI test verify image view with jet pack compose?

I have

sealed

class

AppState

with 4 states (3 object and 1 one data class having 1 immutable property). It is used in

ViewModel

as private

MutableLiveData

and exposed to activity as

LiveData

I'm using it in compose using

LiveData.observeAsState()

Now the issue I'm facing is that when I use the variable

State<AppState>

(variable name is appState) using

when

block I'm able to access that 1 data classess property but I'm getting compilation error (Smart cast to 'AppState.Success' is impossible, because 'appState' is a property that has open or custom getter) Code snippet inside thread
