I have a function that can receive either integer as a string (in case an integer will get from context.getString), in java I create two different functions whereas the one that receives integer only makes the call to context.getString and calls the function which is expecting a parameter string. In kotlin have some more elegant aprouch, or is it recommended to do likewise?

is there any refactoring option on Android Studio/IntelliJ that converts ?

fun getFoo = ...

to

val foo get() = ...

Are there sample implementations of the tinder animation in Kotlin?

If a class has a member function, and an extension function is defined which has the same receiver type, the same name and is applicable to given arguments, the member always wins.

Does anyone have recommendations for managing an asynchronous UI state with Kotlin and RxJava? Jwharton’s talk here was great, but I’m not sure if there have been any developments since then:

What's your opinion on Picasso? That seems to be the recommended library to use to easily grab urls and (for my case) project resource drawable images

Hi, I’m trying to use a ViewModel to chain queries to an API. eg, The first query returns an invoice with customer id’s, the second query returns the customer data related to those id’s. From what I’ve been reading I need to use a MediatorLiveData to observe LiveData objects representing the API calls, but I’m not really understanding how to chain these and only return a result, once I’ve received both responses. Does anybody have some documentation or an example to help me out here?

What would be nice if there's a way to simply get all images in a file or all available resource ids for resource. I know Kotlin has a "walking" function to grab names of files

Are i understand something wrong or it's kotlin bug? I have : data class Foo ( val initializationType: InitializationType) { val isInitDefault = initializationType == InitializationType.Default } and when i call this val it's working incorrect, but when i transform it to fun or just add custom get() = initializationType == InitializationType.Default it start working like it should what the problem? P.S. InitializationType it's enum

anyone know where the code for data classes annotated with

@Parcelize

gets generated to? Can't seem to find them in the build folder

for a resource

TypedArray

, do I need to implement an iterator to be able to loop through it?

Hey I am working on a library in Kotlin In this library, if I have some variable inside

companion object

, than those variable are treated as static in Java But when I try to access those variable in a java project, which is using library, It is like :

MyClass.Companion.abcVariable

I searched and found I had to append @JvmStatic in front of variable so that java can access it directly like :

MyClass.abcVariable

This works for

classes

but for

interfaces

it requires a min API level of 24 and my Min API level is 21 Is there any other way to directly access companion object variables for

interface

in API projects supporting min API level less than 24 like :

MyClass.abcVariable

How can i override a property and add new properties to it ?.. currently getting

Hey guys.. I have a question regarding a kotlin library I’m building for the JVM. This library should be usable in android projects and regular kotlin/java projects. I’m targeting Java 1.8 which is only partly supported by android 4.4 - However I need the library to perfectly work with android 4.4. I have had some issues where some features of java 1.8 would obviously not work on Android 4.4 and I’ve only detected those at runtime on android. What method would you suggest to avoid this issues…? Is there any linter that would check wether there are features of Java 1.8 I’m using in my code that wouldn’t run on android 4.4? Thank you in advance 😛

when would

fragment

forget what got put in its

setListener

is anyone having problems with android studio when editing gradle files? it’s super laggy when I start typing into a .gradle file…

Could somebody share the topic/faq/story on how to test android app with roboelectric or sth else

not sure what is “.numeric”, probably some more sofisticated algorithm that supports such comaparsion out of the box The problem that you just cannot compare strings 9 and 11. Also, you cannot just convert string to int, because you must also sort by letter My solution is pretty simple, you just sort by int number, then by letter. You can move number split to comparator, cached value just more efficient (parse only once), but not necessary (updated sample)

Hey guys .. how can i get AppCode Plugin for IntellJ

@jw So the official Kotlin style guide is contradictory against the Android style guide. I know they are 2 separate style guides, but my team has been using them as complementary, as have other projects like ktlint. i.e. Android Kotlin style guide recommends a continuation indent when giving function params their own line, while the kotlin style guide recommends a normal indent. Is this intentional, meaning the guides are meant to be used independently of one another? https://android.github.io/kotlin-guides/style.html#functions https://kotlinlang.org/docs/reference/coding-conventions.html#function-formatting

I just got the most fun buildcache bug ever : I had a if(something) {} block, when something was false, it would still go in it. when I changed for if(false) {}, same issue when I removed the block, same issue I tried on another device, same issue I did clean and rebuild, same issue ./gradlew cleanBuildCache => fixed !
