I assume you mean to say, you want to return after

checkOrginization()

method after completing the loop in success listener. Am’I getting it right?

why this code response body return null but the header is success i tried to change "@GET" annotation value from

cases_by_country.php

to

/cases_by_country.php

and even i change

API_BASE_URL

value from

<https://coronavirus-monitor.p.rapidapi.com/coronavirus/>

to

<https://coronavirus-monitor.p.rapidapi.com/coronavirus/cases_by_coutry.php/>

still it returns null why ? 🤔

I was using

EditText

and I had

addTextChangedListener

. I switched to

TextInputEditText

and I can't find the listener now!

Hello guys, when I google Kotlin functions I get multiple results from the official docs which is great but not every reference has examples. What is the best way to view docs that have examples ?

In Android Studio, is there a quick way to convert a function to a property (and all usages, of course): e.g.

fun length(): Int

to

val length: Int

?

Has anyone subscribed to the raywenderlich tutorials? Just wondering about their quality.

Hello guys, I've a question, from my webservice it comes like a flag true or false, so on my adapter of my recyclerView I have to print one color or other depends of the flag, do I have to add this logic in the Viewholder? Also is there any other way to test this logic besides of UI? I do the mapper to my domain object, and it's tested.

Does anyone have an example of onboarding flow using navigation component ? For example a intro slider using viewpager ? I have seen the conditional navigation docs but I don't understand how this would fit into what the docs recommend.

Hello I have a question relating inner classes in Java I'm having troubles with. I have a utility class in which I hold various enum classes. There is no problem accessing them in Java classes, but when I try to access them in a Kotlin class, I get Unresolved reference: UtilityClass Utility class looks like this

public final class UtilityClass {

    private UtilityClass() {
        // Utility class
    }

    public enum FirstEnum {
        FIRST_OPTION, SECOND_OPTION, THIRD_OPTION, NONE
    }
}

While the the data class in Kotlin is as follows

data class KotlinClass(val option: UtilityClass.FirstEnum = UtilityClass.FirstEnum.NONE)

Does anyone maybe know why I get "Unresolved reference: UtilityClass" trying to access the enum from my utility class? Both classes are in same package, so no imports required, I've tried moving either class in another package, but the issue persists I had no luck finding a solution for this, I can't find anything even remotely similar to this problem

Hello All, I am getting below error. any suggestions

I am Planning to develop apps for Android and IOS platforms. I came across Kotlin/Native technology and found a huge potential to have shared logic via a single Kotlin/native module. But from tech docs and samples I’ve seen only pinch of an iceberg . I am wondering if it’s stable enough for production. Because still while running builds I get a message “Kotlin/native is experimental” So do you recommend Kotlin/Native to be used for production Android/IOS apps? React with 👍🏾 for yes 👎🏾 for not yet

Hi, guys. Is there a way to merge two org.json.JSONObject using Kotlin? I’ve already googled it, but it was unsuccessfully. Maybe someone has an approach for that? Thanks in advance.

Such a question - I need to send http requests, but I need to bind not to the activity lifecycle (in my case, viewModelScope), but to the life cycle of the app itself) I don’t really want to use the service for this. Why is GlobalScope bad in my case?

Does anyone know how I would be able to tell if my final apk is bundling kotlin reflect? I heard that if you add Moshi and moshi-kotlin it will have to pull in the kotlin reflect lib which in turn would make your apk ~2MB larger in size. I've used the apk analyzer and I wasn't able to find anything that large, but curious if anyone knows better than me.

Anyone have any solution to resolve concurrency issue on ArrayList? Firebase crash log:

Fatal Exception: java.util.ConcurrentModificationException
       at java.util.ArrayList$Itr.next(ArrayList.java:860)

My code:

val dataConversation = ArrayList<Conversation>() // global

// in background ( I have use Epoxy - Airbnb )
val cloneListConcurrency = arrayListOf<Conversation>().apply { addAll(dataConversation) }
        with(cloneListConcurrency.iterator()) {
            forEach {
// do something to display 
}}

// in background
fun deleteConversation(conversationId: String?) {
        for (index in 0 until dataConversation.size) {
            val item = dataConversation[index]
            if (item.id == conversationId) {
                dataConversation.removeAt(index)
                break
            }
        }
    }

Many Thanks.

anybody has other suggestions or tips for this? Thanks in advance!

Hey kotliners, 🙂 Does anybody have some opinion about KTX:

isVisible

,

isInvisible

,

isGone

extensions? I mean, first time I implemented KTX in my project I expected something like:

gone()

,

visible()

,

invisible()

Not the best channel to ask this but I'll smuggle very quickly a non-Kotlin question, since people here are very responsive 😉 Does anyone know how to differentiate between internal/alpha/beta releases in Google Play? They seem to have the same URL? And no alpha/beta text anywhere?

how can I import data from excel to POJO in my app?

anyone know of any frameworks/APIs/libs for incorporating the ability to record and stream live video from an android app ?
