Hello guys, I'm new here, and I'm new to android programming, i am hoping to learn from you and hopefully guide people in the future.. I hope I am welcome?

Hi! I created a new video about “What is a Flow in Kotlin?”

Hi is there any way to get real time.. I’m going to build app which have license validation.. for the very first time the internet connection is must.. after noo need of internet. We storing expiry date in encrypted way locally. With that we compare local date and time and getting to validation expired or not. Issue: if user changing their time in setting everywhere time getting changed.. so they bypassing the validation. Is any work arround or idea to achieve validation properly without internet🥲 even they change the time in their device..!! Any idea should he appreciated.

I am trying to generate baseline profiles for the app. As it seems this would be good to have those generated on every release build as code changes constantly and the reason for a new build is of course code change so baseline would need an update. Problem I see with that is that code that the baseline is ran on should be the closest to production one, meaning f.e. not mocking data on network layer i.e. calling backend services for data using Retrofit etc.. This means a test running on a CI and a network failure, test instability, change in data responses so test fails to match some results will result in a build failure. This seems to be a high risk thing from maintenance purpose. Is there any smart way to tackle this? Or maybe I am overthinking this and the baseline profile generation attached to CI release build process is over engineering? Maybe a baseline profile generated locally now and then and updated like every 2 weeks is enough? What do you think?

Hi folks Is there any platform or slack channel to find remote jobs as an Android or KMM developer?

Hyy guys i posted this question please help me for this https://stackoverflow.com/questions/74569405/how-can-we-get-cancel-button-listener-from-system-generate-notification-by-downl

It's about download manager

I am usinge the

Intent.ACTION_OPEN_DOCUMENT_TREE

to let the user choose a directory and get access to this directory. It works but unfortunately the access is only temporary when the user closes the app and opens the app again i need to open the directory picker again. Especially for development this is very unpleasent. Of course i could ask the user for MANAGE_EXTERNAL_STORAGE permission but Google do not want this anymore for normal apps. My app is just a video player. But i need access to the directory to load subtitle files.

Hey guys, just out of curiosity. Is there a way for android studio to copy @ Composable annotation when generating overriden methods?

Hey everyone! I have a endpoint that returns replies of a post, and the structure is something like that:

data class PostReply(
  val author: String,
  val body: String,
  val replies: List<PostReply> // can be infinitely deep
)

I’ve created one regular data class, and another with serialized annotations. But I cannot think a good way on how to map

replies

recursively. I tried that but didn’t work:

fun PostRepliesResponse.toModel() = PostReplies(
    //...
    replies = replies.map { reply -> reply.toModel() }
)

Can you guys help me?

Hi everyone! I was wondering if somebody could help me. I'm new on StateFlow and I found an issue developing my app: I have a layout with a RecyclerView, so whenever I use _state.value.copy( .. ) my Recycler refresh losing its position on scroll... I would like to keep that scroll position. How can I update my UiState without losing the scroll? 🙂

Hi everyone! I have an interface that is implemented by a few classes and I have a "List<Interface>" that I have to save in my Room DB. Every class has its own DAO, but I have a BaseDao too which defines Insert/Update/Delete methods for all the other DAOs. At the moment I'm simply filtering the list with the "filterIsInstance" method to get the class of the objects(I'm doing it for every single class that implements the interface) and then I'm calling the specific class DAO to insert/update/delete the entity. Is there a better way to do this? In particular, I'm pretty sure that I can avoid filtering the list for every type of class but I don't know how

So I’m looking at using KMM to initially share our model classes between IOS and Android dev, what is the best way of doing this, should the KMM module be created in Intellij AppCode or Android Studio. My initial thinking is that I have a separate GitHub repo for KMM modules build in intellij then this gets imported via gradle into appCode (IOS) and Android Studio (Android). Is this the recommended approach

Hi friends 👋 I have an Android SDK with no UI logic that at the moment I use the

com.android.library

gradle plugin to help build. I have a very small sliver of Android dependencies and would now like to convert this to an SDK that can run on our Java backend but still be written in Kotlin, of course. Has anyone had experience with something doing something like this? Where should I start? I think that all of my library dependencies will happily function outside of Android in an in a pure JVM apart from these: 1.

com.android.tools:desugar_jdk_libs

2.

androidx.annotation:annotation

3.

androidx.datastore:datastore-preferences

Should I create two SDKs one of which is

-core

and the other a slim

-android

add on? Or can I get away with a single SDK?

Hi guys 👋, using Compose and Paging with Room, is there a way to mutate the items without refreshing the entire list? At the moment, I have an implementation of the RemoteMediator meaning that I can fetch data from the API and store it in DB, but when I perform the delete operation the entire list is "invalidated" therefore all the new data will be fetched again. Do any of you guys know a way to bypass this challenge?

Hello folks, in a project I have a

Parcelize

-annotated data class that contains a property whose type is a value class. E.g.:

@Parcelize data class Example(val id: Id) : Parcelable

@JvmInline value class Id(val long: Long)

With Kotlin 1.6.10 this compiles and work. However, after updating to Kotlin 1.7.20, I started getting the following error a compile time:

Type is not directly supported by 'Parcelize'. Annotate the parameter type with '@RawValue' if you want it to be serialized using 'writeValue()'

I'm not sure I understand why this stopped compiling, but is using

@RawValue

the actual solution or is there a better one? It feels like a workaround that could break at runtime if the wrapped type changes to one that isn't

Parcelable

.

Hi 👋 I was working in existing application in which it has more than 5 api calls in the viewmodel through retrofit. When fetching api call it has showing loader to main screen and block user untill we get data from response. Some are dependent to each other but some are not i.e. Login session dependent on customer data etc. All response are huge in data so may be it taking time to load. I read the review from play store, its frustrations for user and giving bad reviews. This project is growing day by day. I know you guys asked why this api calls in single screen and reason behind this is the application is healthcare. We make a survey from customer and they want there results in homepage. I already read the doc and everything is up to according to doc. I don't want spoonfed, but I need guidance for you guys. Many thanks

How to set bottom nav bar items centred for landscape or tablet mode. They're too far apart. (Jetpack compose)

What is the best way to measure the performance of a composable and get the data from the user base using Firebase traces (and not just tracing on our own device(s)) ? The main question here is about where to start the trace and where to stop it. Posted on #compose earlier but did not get any response.

Migrate the deprecated onbackpressed function when you targeting Android 13, check if you want!! #android #deprecated https://medium.com/@fierydinesh/migrate-the-deprecated-onbackpressed-function-android-13-d0d556244272

Hi, I’m starting developing a new app, all retrofit calls will be async, if I have a rest call that returns a single value would people still recommend using Flow

I know flow will give you a stream for multiple values, but I think from an architecture perspective it makes sense to use Flow also for a single value, instead of LiveData

doing some google searches it looks like this is the approach to go with, LiveData looks to be the old way of doing things and will be deprecated at some point in the future

so I’m not really that bothered if it is to be officially deprecated, more just whether people would recommend only using Flows and StateFlow

I’m fairly new to android dev so at the moment basing an architecture on https://github.com/android/nowinandroid
