Looks like you're trying to implement a method that already exists on enum classes, the valueOf() one. Is either that or you misunderstood enums and are trying to use them as normal classes (enums cannot be instantiated)

How do you guys handle name shadowing? Do you even care?

The problem, for me, would lie in a situation where you require Robolectric for your Presenter (which points to an abstraction failure)

I’m trying to figure out which version of Kotlin my compiler using. Is there a way I can find this out?

Has anyone ran into

NoClassDefFoundError

when building with kotlin files from CI, but not locally from Android studio?

https://androidstudio.googleblog.com/2017/06/android-studio-30-canary-5-is-now.html Anyone tried it with Kotlin? Any new issues?

I am trying to use Android data binding but have started to get this error:

how i run first app with kotlin

Hi ! I need to document Kotlin code in an Android Project, but looks like JavaDoc doesn’t work. Do anyone knows a good documentation tool with Android and Kotlin ? I would like to just have to create comments with keywords (like javadoc) and just generate documentation from this

Sorry for none kotlin question. I’m looking for view such as MapView, which can be draggable and moveable in x and y alias. What else can be used??

use 1.1.3 instead

Jacoco works, but has issues with inline functions coverage, but mostly works

I am wondering, where is stored

-Xreport-perf

for android project? I added the flag:

tasks.withType(org.jetbrains.kotlin.gradle.tasks.KotlinCompile).all {
    kotlinOptions {
        freeCompilerArgs = ['-Xreport-perf']
    }
}

And see in kotlin daemon logs, flag was added. But no output about this

val config = RealmConfiguration.Builder() .schemaVersion(1) .deleteRealmIfMigrationNeeded() .migration(MyMigration()) .build() Realm.setDefaultConfiguration(config)

Hey guys, I recently updated to Canary 5 (along with gradle 3.0.0 alpha5), and I got this crash the minute I load up my app

‼️ Hi, I’ve got a weird issue: Currently we a using kotlin version “1.1.1” in our android project. I’d like to update to the the latest version (“1.1.3"). But if I do so and I compile the project I get the following error:

Error:Uncaught translation error: com.android.dx.cf.code.SimException: at stack depth 2, expected type kotlin.ranges.IntRange but found int
Error:1 error; aborting
Error:Execution failed for task ':app:transformClassesWithDexForStudoDebug'.
com.android.build.api.transform.TransformException: java.lang.RuntimeException: com.android.ide.common.process.ProcessException: java.util.concurrent.ExecutionException: com.android.ide.common.process.ProcessException: Return code 1 for dex process

Has anyone experienced / solved this issue? ‼️

Just that autocomplete is totally lacking

is it a good idea to use Room entities for other things like json parsing and parcelable etc ?

but how correctly i can make transition on some fragment from my viewHolder, when i make click on someView?

someView.setOnClickListener {
                val manager = (context as Activity).fragmentManager
                manager.beginTransaction().replace(R.layout.fragment_transaction_edit, TransactionEditFragment()).commit()
            }

for me that way doesn t work

Shameless plug: I just open sourced Tolbaaken, a Kotlin logging library for Android with zero overhead. https://github.com/Q42/Tolbaaken Feedback is welcome

but which library is the best to use in the mean time?

@nounours I'm using Conductor in multiple production apps -- it's fantastic. Especially nice if you need to do nested views -- dealing with nested Fragments is a nightmare but is easy with Conductor's Controllers. Highly recommend you at least try it and see if its worth bringing into your project

@nounours I would use this opportunity to play with the new Architecture components.

The reason I think the issue is around stub generation, is because if I declare an empty interface (even if it is in kotlin), make the dao interface extend this empty interface and only reference the empty interface in the dagger module method signatures, I don’t get an error

I think you need to write wrapper to convert your List<List<string>> to realm objects

Alt+Enter (fastfix) on your class/method -> Create test

@sam.oen It depends on your use case. You can use in-app payments without own server if all in-app purchases are completely local. But people with root devices can hack it and buy something without payment.

@lovis how exactly do I do this? the collection item itself is not null but the property `name`might
