Good afternoon, colleagues. How to check the entered value of type :string for the fact that it is not :integer.

Hello! Is there any option to turn on build.gradle*.kts* by default when creating Android projects/modules, etc?

Hello everyone, I wonder is there a tool that can find functions depend on the type of input and output 😅? I’ve decompiled an apk and I cannot see the function names in the apk source code. I guess the functions are Android build-in functions.

I am trying to parse a large JSON response (3 MB), either to

JsonElement

or to my custom structure and I am seeing an

OutOfMemoryError

every single time. Is this expected? Perhaps I am just close to the Android memory limit?

Hey everyone! I have a question about Gradle configuration with Kotlin DSL in android project. I want to set the classpath of the project in "remote" way. I think the best way to achieve it is with a custom plugin, but i dont quite understand how to do it ¿Does anyone know how to do it? Sorry for my bad English 😁

I am trying to use kotlin flow in Service to send data and collect it through Binder in activity. But after testing, flow can only be collected once, is this some cross-process limitation? Is there a better way to listen data changes in service?

Hi, I integrate Firebase Crashlytics into my app unable to get crash report to Firebase Dashboard. please any one help me Error log : --------- beginning of main 06-06 12:19:47.897 7577 7577 I FirebaseCrashlytics: Initializing Firebase Crashlytics 18.2.4 for vidma.screenrecorder.videorecorder.videoeditor.pro 06-06 12:19:49.011 7577 7748 E FirebaseCrashlytics: Settings request failed. 06-06 12:19:53.764 8553 8553 I FirebaseCrashlytics: Initializing Crashlytics 17.2.1 06-06 12:19:55.118 8553 8778 E FirebaseCrashlytics: Settings request failed. 06-06 12:20:20.393 11343 11343 I FirebaseCrashlytics: Initializing Crashlytics 17.3.0 06-06 12:20:23.049 11343 11416 E FirebaseCrashlytics: Settings request failed. 06-06 12:20:35.474 12324 12324 I FirebaseCrashlytics: Initializing Crashlytics 17.2.1 06-06 12:20:38.450 12324 13013 E FirebaseCrashlytics: Settings request failed. 06-06 12:22:10.134 16037 16094 E FirebaseCrashlytics: Settings request failed. 06-06 12:22:54.911 18209 18209 I FirebaseCrashlytics: Initializing Firebase Crashlytics 17.4.1 06-06 12:22:58.295 18209 18264 E FirebaseCrashlytics: Settings request failed. 06-06 12:22:59.844 18418 18418 I FirebaseCrashlytics: Initializing Firebase Crashlytics 18.2.5 for com.flipkart.android 06-06 12:23:00.905 18418 18537 E FirebaseCrashlytics: Settings request failed. 06-06 12:23:39.682 20031 20031 I FirebaseCrashlytics: Initializing Firebase Crashlytics 18.2.4 for com.weather.Weather 06-06 12:23:40.050 20031 20073 E FirebaseCrashlytics: Settings request failed. 06-06 12:23:47.309 20273 20273 I FirebaseCrashlytics: Initializing Crashlytics 17.2.1 06-06 12:23:50.844 20273 20422 E FirebaseCrashlytics: Settings request failed. 06-06 12:24:21.804 21774 21774 I FirebaseCrashlytics: Initializing Crashlytics 17.2.1 06-06 12:24:23.038 21774 21819 E FirebaseCrashlytics: Settings request failed. 06-06 12:24:27.597 21979 22136 E FirebaseCrashlytics: Settings request failed. 06-06 12:24:38.776 22823 22823 I FirebaseCrashlytics: Initializing Firebase Crashlytics 17.4.1 06-06 12:24:42.118 22823 22874 E FirebaseCrashlytics: Settings request failed. 06-06 12:27:57.856 25169 25169 I FirebaseCrashlytics: Initializing Firebase Crashlytics 18.2.11 for com.ibot.cyrano.android 06-06 12:27:58.125 25169 25373 E FirebaseCrashlytics: Settings request failed. 06-06 12:28:40.534 26610 26610 I FirebaseCrashlytics: Initializing Firebase Crashlytics 17.4.1 06-06 12:28:47.893 27100 27100 I FirebaseCrashlytics: Initializing Firebase Crashlytics 17.4.1 06-06 12:29:48.831 30015 30015 I FirebaseCrashlytics: Initializing Firebase Crashlytics 18.2.11 for com.ibot.cyrano.android 06-06 12:30:19.631 30015 30015 D FirebaseCrashlytics: Crashlytics automatic data collection ENABLED by API. 06-06 12:30:19.632 30015 30015 D FirebaseCrashlytics: Handling uncaught exception "java.lang.RuntimeException: Cyrano Studio Crash" from thread main 06-06 12:30:19.718 30015 30080 D FirebaseCrashlytics: Loaded userId user123456789 for session 629DA5E403900001753FF252495DEDE7 06-06 12:30:19.758 30015 30080 D FirebaseCrashlytics: Loaded userId user123456789 for session 629DA5E403900001753FF252495DEDE7 06-06 12:30:19.776 30015 30080 D FirebaseCrashlytics: Opening a new session with ID 629DA60303070002753FF252495DEDE7 06-06 12:30:19.781 30015 30080 D FirebaseCrashlytics: Crashlytics automatic data collection ENABLED by API. 06-06 12:30:19.782 30015 30080 D FirebaseCrashlytics: Logging app exception event to Firebase Analytics 06-06 12:30:19.796 30015 30080 D FirebaseCrashlytics: Sending report through Google DataTransport: 629DA5E403900001753FF252495DEDE7 06-06 12:30:19.827 30015 30080 D FirebaseCrashlytics: Crashlytics report successfully enqueued to DataTransport: 629DA5E403900001753FF252495DEDE7 06-06 12:30:19.827 30015 30080 D FirebaseCrashlytics: Deleted report file: /data/user/0/com.ibot.cyrano.android/files/.com.google.firebase.crashlytics.files.v2:com.ibot.cyrano.android/priority-reports/629DA5E403900001753FF252495DEDE7 06-06 12:30:19.827 30015 30015 D FirebaseCrashlytics: Completed exception processing.

I have one question my gps location update without device move Any idea? How to resolve?

But, it's regarding Android And i code done in Kotlin

So any one have idea why gps behavior like this

I have some questions related to the

kotlin-parcelize

plugin and how best to use it in a modularized project setup: In an effort to modularize a monolithic Android app module, step 1 (ideally) is to extract common model classes into standalone modules for re-use. Based on the project setup, we want these new modules to be plain JVM modules (no

com.android.library

plugin). This becomes problematic if any of the model classes are

Parcelable

and utilize the parcelize plugin -

kotlin-parcelize

can't run in a module without applying the

com.android.library

plugin. Any recommendations on how to work around this? I can come up with two options myself, but neither one is necessarily ideal; I'm curious if anyone has other ideas or recommendations? 1. Make the common model not Parcelable, create a new Parcelize-specific model class local to the app module, and convert back and forth between the two. 2. Persist the data a different way, or use a different serialization strategy, and remove the

@Parcelize

annotation on those common models.

Hey all, I’m trying to implement the okhttp Authenticator to re-authenticate upon access token expiration (401). My question is how to handle when multiple networks calls are sent and return with 401. I tried to annotate the function with @Syncrornized in order to call the remote refresh token API only once instead of for each of the bounced 401 calls. the annotation doesn’t work and i see in the logs that the function that is annotated with it still being called more than once at given time. any suggestion/help?

Hello, how do I write a when clause for density range? I don’t want to hardcode magic numbers

val scale = when (Resources.getSystem().displayMetrics.densityDpi) {
    DENSITY_MEDIUM -> 1
    ...
    else -> 1
}

above works but below not

val scale = when (Resources.getSystem().displayMetrics.densityDpi) {
    DENSITY_LOW..DENSITY_MEDIUM -> 1 -> // compile error
    ...
    else -> 1
}

It gives

Incompatible types: IntRange and Int

Hi there! In many articles about collecting Flow in an Android lifecycle aware manner there is

SharingStarted.WhileSubscribed(5000L)

in

stateIn

operator. Where does the 5000 come from? Why not zero and why exactly that number? Thanks in advance.

I have a Database entity and DTO and a domain model I mapped the network DTO to my domain model in a usecase that fetching a list of item Now I have another usecase that fetches from cache storage But would be observed in the same fragment as the first one which is the list of item form network Usecase 1 fetch from API Map to domain model observed in view in a recycler view Usecase 2 user saved a particular article to disk I then fetch from cache storage and observe in the same view in another recycler view My question is should I create a different domain model for that of cache Entity and for DTO Because in the view model I have a UI state For example

data class UIState(
val itemlist = List<ItemEntity> = list of()
Val isLoading ......
)

If I update itemlist uiState with data fetched from network How can I differentiate it from data fetch from cache because I need these distinctive data in 2 different recycler view

Hey guys, I want to combine flow and string. I am trying to do that, but I am getting problem.

        query.value = value
    }
val filteredTopics = MutableStateFlow<List<ConsulationsTopics>>(emptyList())
 val filteredCategories = query
        .debounce(200) // low debounce because we are just filtering local data
        .distinctUntilChanged()
        .combine(filteredTopics) { queryText, categoriesList ->
            val criteria = queryText.lowercase()
            if (criteria.isEmpty()) {
                    return@combine filteredTopics
            } else {
                categoriesList.filter { category -> category.title?.lowercase()?.let { criteria.contains(it) } == true }
            }

Hey everyone 😄 Can anyone look at this snippet and tell me why

listOfRides.map { ... }

freezes the app?

private fun initUserAndRides() {

    // TODO: Fix this
    viewModelScope.launch {

        val userInstance = repository.getUser()
        val listOfRides =
            repository.getRides()

        _user.postValue(userInstance)

        withContext(Dispatchers.Default) {
            val listOfUserRides = listOfRides.map { UserRide.createUserRide(userInstance, it) }
            _rides.postValue(listOfUserRides)
        }
    }
}

Please know that

UserRide.createUserRide(userInstance, it)

is computationally-expensive. Also,

repository.getUser()

and

repository.getRides()

are suspend functions implemented by Retrofit.

Hello everyone. I wrote an article about kotlin. I didn't publish yet. Can anyone read and comment? Can you help me?

Hi everyone. I’m working with legacy project and project has sub-projects. Structure looks like:

root_folder:
- build.gradle - top build
- /project1/build.gradle
- /project2/build.gradle

I wanna update kotlin version only for project 1 but I faced with issues, because kotlin version is defined in top build file. Is there any workaround how to re-define kotlin version, android gradle plugin version only in /project1/build.gradle?

This message was deleted.

Is

?.let

not thread safe?

So both

?.let

and

?:

are thread safe? because using

if

gives me smart cast error
