anyone knows any script/plugin where i can change android attribute value to my new value, like android:textColor:="my new value" everywhere in the app. #android-studio

👋 Open question: At which point do you wrap kotlin exceptions into a sealed class / Either / exception wrapper? ViewModel, Interactor, Repository, DataSource, ASAP? I feel at least the exception shouldn’t reach the View layer.

For a person who is just starting on reactive programming, could you drop in the replies on what you think are good resources to learn RxJava and RxKotlin?

I thought Android Studio used to have a refactoring to extract a method to a new class. Or does it, but can't do so in Kotlin?

Hello! I'm a library author, and I'm looking to integrate with the new Dagger Hilt setup. One of the features of my library requires injection into an AndroidX ViewModel. Previously, I have provided this functionality through a custom ViewModelFactory, basically in the same way that AbstractSavedStateViewModelFactory works. I am having trouble figuring out how to do something similar for apps that are using Hilt. Is there a way to provide additional

@Assisted

injected parameters to a class that is using

@ViewModelInject

?

I need help in this question about access modifier in Kotlin: https://stackoverflow.com/questions/62937511/how-to-hide-visibility-of-kotlin-internal-class-in-java?noredirect=1#comment111300497_62937511

Trying to reason about architecture,,, and even though I realize that fragments aren't the best thing out there, and AAC ViewModels aren't the best thing either... I think for a majority projects, there are a ton of benefits to just using what is provided to us from google. Knowing this I'm using a single LiveData to send my UiState to my View/Fragment and I observe the single state. This works really nicely in my opinion... what I still don't know how to do is how to send events from ViewModel to the Fragment via some kind of observable for Events. It seems like this library would be good enough for 98% of cases no? https://github.com/hadilq/LiveEvent

Hey everyone! May you please tell me what blogs and podcasts on Android/Kotlin development you follow and can recommend.

Hi Everyone , I am an android developer from Myanmar. So glad to get a chance to join to this group. May you kindly please share about Kotlin new features and android tech. Is there any update with Kotlin compose ?

Has anyone here got any experience debugging native crashes? I’ve got on occurring in production, which I cant reproduce. I’ve got what looks like a tombstone.. I’ve tried using the ndk tools ‘stack’ and ‘addr2line’ but they’re not giving me any additional information.. Stack just spits out basically the same output as the original dump, and addr2line can’t seem to locate the associated line number.

Hello everyone, this is more of a personal question than a technical one. I've set a goal of improving myself in many aspects of Android Development in the next 12 months to increase my own marketability in the job market. I'm planning to explore most of Jetpack components including compose, how they play out with popular architectural patterns, in what ways Dagger(any dependency injection) should be utilized through out the application, how modular applications differ from traditional monolithic design, to learn details of both unit and UI testing, and etc. This seems a lot considering the time frame and most people would suggest focusing on one thing instead of being jack of all trades. That's why I'm confused and in need of help to figure out what to do. What are your suggestions for a "not so junior anymore" level of Android Developer who has decided to commit his next 5 years to Android Development? What kind of steps should I take today, that will benefit me after 12 months and also 5 years from now?

Hello everyone! If you have sample projects with MVVM, RxJava, Kotlin, Dagger 2 and Retrofit please share with me, for learning purpose🧐 😁. I want to master RxJava so I will be happy to see as much sample projects as you may share🤩

Hello everyone, I want to fire off a REST API call with a Kotlin Coroutine from one fragment then handle the response in a different activity. Any recommendations? I feel like a broadcast receiver and service implementation is too heavy weight for what I'm trying to do.

Anyone have a problem like this when upgrade Android Gradle Plugin to 4x?

com.android.tools.build:gradle:4.0.1 
distributionUrl=https\://services.gradle.org/distributions/gradle-6.1.1-all.zip

My error

Could not resolve all dependencies for configuration ':app:stagingDebugRuntimeClasspath'.

Anyone familiar with https://github.com/dropbox/Store and willing to explain how it's meant to be used? I thought it was straight forward, until I couldn't find a way to get all the data? How should on do a

getAll

on the data in the store?

Does anyone have any insight on how I could build this radial selection in Android? This is a screenshot from the iOS app. I’m still pretty new to Android and I’m not even sure where to start Googling.

Hello guys, Does any one have a sample MVI project with Coroutines/Flow or LiveData (Without RxJava) + DI

Is there any

@Parcelize

equivalent for saving custom view state?

instead of findViewbyId

@Madalin Valceleanu Nice to meet you! I was going to study with your project, but it's blocked in the execution part. Can I ask you a question?

Running into a strange issue with

View.generateViewId()

here with programatically created Views. It only outputs sequential IDs starting with

1

, and

onRestoreInstanceState

on these Views isn't called at all upon restore. Any ideas?

Hi , Is this going leak the memory , Shared view model concept - https://developer.android.com/topic/libraries/architecture/viewmodel#sharing Both fragments takes the reference of Activity View model , activityView model stay as long as activity stays . does it going to keep the sharedviewmodel reference once it is created till the point activity destroys ??

Is dynamic delivery a must know now? I am thinking of putting in the effort to get a good grasp on it, but I am not sure if it's a good idea to focus on that or just stay with the standard multi module approach.

Hi, I have a channel for offering packets:

val responsePacketsChannel = ConflatedBroadcastChannel<ResponsePacket>()

ResponsePacket is a interface because I have multiple packets which I want to offer, e.g.

ParameterPacket: ResponsePacket

or

TimePacket: ResponsePacket

. Now I'm wondering what would be the proper way to differentiate between the specific packets when I start to observe them. My first thought was using

Pair<ResponsePacketType, ResponsePacket>

combined with an enum

ResponsePacketType

->

val responsePacketsChannel = ConflatedBroadcastChannel<Pair<ResponsePacketType, ResponsePacket>>()

Is there maybe a better solution?

Hello guys, If you are using coroutines in your Android Projects, this could probably help you to boost it https://blog.loop-ideas.com/android-livedata-coroutines-the-next-level-with-map-and-switchmap-extensions-b56a2f2f2ba7

Hi. How can I zip two flows when each flow’s result is represented like sealed class? sealed class Response<out T> { object Loading ... data class Data<T>(val data: T)... data class Error(val error: Throwable)... } I see there is Flow.zip() operator but anyway it’s a lot of combinations and I have no idea how to cancel flow when one of the error received.. So, what’s the best Kotlin/Flow approach to deal with it?

Does anyone faced this problem?
