What are people doing to synchronize an arraylist with Kotlin?

How can I send a get http request?

Not kotlin related, any consensus on BottomNavigation implementation? With ViewPager or without? Provided examples, where they create a new fragment on every tab click are pretty detached from reality.

It works for me

Hi, I have a query: in case of multi-threading, why subscribeOn() does not work for PublishSubject?

Question about

MatchGroupCollection

and

getMatchResultNamedGroup

On which Android version is it supported if any?

is

@Parcelize

still experimental?

Not really a Kotlin question, but more of an Android filesystem question: Is there a way to access last accessed time for a file on Android? For example, activating ‘atime’ tracking. On Linux filesystems, one can generally use stat or lstat to get the value: long lastAccessTime = Os.lstat(file.getAbsolutePath()).st_atime; but it seems that if the OS doesn’t actually track it, it will just return a default value

Google forced me to update dependencies in order to get the build to sync. Oh how I love google for forcing this on me...

I’m not sure if this is the right channel to ask but let me give it a try. Apks built with Kotlin 1.3.0 are failing in dex2oatd class and method verification while building AOSP ROM. Looks like there is some issue with newly introduced unsigned types or inline classes in AOSP build. But we are not using both of those features. Even though APKs are built and working fine, they are failing in dex2oatd verification in AOSP ROM build. Error is,

dex2oatd F art/compiler/driver/compiler_driver.cc:661] Had a hard failure verifying all classes, and was asked to abort in such situations. Please check the log.
dex2oatd Fdex2oatd I art/runtime/verifier/method_verifier.cc:333] Verification error in int kotlin.UShort.compareTo(java.lang.Object)

Any idea why this might happen? Everything works fine till Kotlin 1.2.70

Hello, please help .I'm writing bugs when installing. How should I proceed? I tried unistall and admin interface the same error 😞 (Kotlin,AS 3.2.1) Thank You

I’m not really good at network security aspects of Android. Could you recommend any source of knowledge / course for dummies explaining stuff like SSL / TLS, Certificate pinning, KeyStore, etc.?

Can anyone help me

When should I use

context!!

versus

context?

in my Fragments? I'm thinking using

context!!

in my lifecycle methods and

context?.let{}

where I get callbacks

Does anyone know a convenient way to get current selected flavor inside gradle script?

Hello! I just started to learn both Kotlin and Android with "Kotlin for Android developments". Could you advice some basic and easy to read book about Android environment? ( i have some general programming experience)

Can Android libraries made with kotlin be used in Java projects? And do things like extension functions carry through in your kotlin projects using the library?

Hi guys, whats rx equivalent of android handler.post? i.e I have a object that has it own single threaded scheduler on which it has a queue loop. bla bla sometimes recursion happens, I need to post a runnable to the end of the queue

Did someone get kotlin scratch files running in android studio? I am getting this error:

Cannot access script base class 'kotlin.script.templates.standard.ScriptTemplateWithArgs'. Check your module classpath for missing or conflicting dependencies

Seems like I misconfigured. I also cannot switch to the Scratchfiles view as described for intellij here https://www.jetbrains.com/help/idea/2016.3/scratches.html

Hey, I have a hard time using

Parcelize

from the Kotlin Android Extensions with Gradle KTS. I just created a minimal sample project, that highlights the error: https://github.com/ChristianBecker/parcelize_kts • If I use

app/build.gradle

everything works fine • If I use

app/build.gradle.kts

(by un-commenting line 4 in

settings.gradle.kts

) the Kotlin Compiler is unable to find

Parcelize

on the classpath and fails the build:

e: […]/ParcelizeModel.kt: (4, 24): Unresolved reference: parcel
e: […]/ParcelizeModel.kt: (6, 2): Unresolved reference: Parcelize
e: […]/ParcelizeModel.kt: (7, 6): Class 'ParcelizeModel' is not abstract and does not implement abstract member public abstract fun writeToParcel(p0: Parcel!, p1: Int): Unit defined in android.os.Parcelable

Is this the right channel, or should I post this in #gradle, or somewhere else? (Sorry for copy-pasting, I just wanted to extend the scope)

When browsing the documentation, how do you switch between the docs for Java and the docs for Kotlin? For example: • https://developer.android.com/reference/androidx/lifecycle/package-summary • https://developer.android.com/reference/kotlin/androidx/lifecycle/package-summary Other than going to address bar and typing in or deleting kotlin in the right place

If you use R8 you don't need to do anything

Does the Kotlin Repl work with Android studio 3.2?

I'm using moshi's generated adapters and I don't want to run kapt while developing because of build times. However when testing, I want to run kapt on my sources. Else I'll test an artificial situation which is different from my production code.

I would achieve this by modularizing the moshi classes into their own module. Such that only changes to that module will cause the moshi kapt to run again. Advantage, your tests and release build times will also be faster, unlike any hack solution that only makes debug builds faster.

Trying to debug my first trivial app made with Kotlin with Android Studio. No matter if I tap "step over", I still end up in the Java source code of the Android framework. Is that normal? Apologies if this is not strictly Kotlin related.
