if you get

NumberFormatException

than your string probably isn't able to be represented as a

Long

I'm getting compile error and Android studio lags a lot if I put i if I put it in the Main activity class as a string

Hi, I'm new to kotlin how can i return data from an anonymous function?

val flowable = mWebService?.getData
            flowable?.subscribeOn(<http://io.reactivex.schedulers.Schedulers.io|io.reactivex.schedulers.Schedulers.io>())
                    ?.subscribe({ response ->
                        Logger.i(TAG, "onNext $response")
                        return true //<------------ how do I return this
                    }, { throwable ->
                        Logger.i(TAG, "onError $throwable")
                    }, {
                        Logger.i(TAG, "onCompleted")
                    })

Switch to using coroutines. You can't use Rx that way...has nothing to do with Kotlin...

Hi, does anyone know this error: Error:Execution failed for task ':app:transformClassesWithJarMergingForDevDebug'.> com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: org/webrtc/Camera1Session$2.class Duplicate class of 2 library twilio and Sora

Hey has anyone tried the Koin Dependency injection library on a large project?

It seems not ready for MVVM yet.

Hey, does anyone have any good starter tutorials for android using kotlin?

Hey whats better , Anko or XML with data binding. if you were creating a production app which one would you choose

hello, should I still use kapt for android with AS 3.0 or I can use default annotationProcessor ?

also you can write

0 -> { -> FragmentA() }

Realm

realm.where(DataPan::class.java).findAll().deleteAllFromRealm()

only deletes DataPan but not fields that are inside

DataPan

like

time

of type

TimeInfo

is not deleted (edited) please anybody help with this

I know I can add them to compositeDisposable object and then clear it later, but do I have just 1 compositeDisposable for the whole app or per activity?

hello there ✋ im trying to create generic

BaseViewModelFactory<VM>

class to provide new architecture component's view models. i wanted to call

isAssignable(...)

function before i create actual viewmodel, to check if everything is fine, but in order to do that, the viewmodel type

VM

have to be reified and i dont know how to call inline reified function from overriden

ViewModelProviders.Factory create()

function currently i got something like this :

abstract class BaseViewModelFactory<out VM : Any>(private val viewModelClass: KClass<VM>) : ViewModelProvider.Factory {

    @Suppress("unchecked_cast")
    override fun <T : ViewModel?> create(modelClass: Class<T>): T {
        require(modelClass.isAssignableFrom(viewModelClass.java)) {
            "Could not instantiate ${javaClass.simpleName} class"
        }
        return createViewModel() as T
    }

    abstract protected fun createViewModel(): VM
}

is there a way to avoid passing viewModelClass in constructor and somehow use reified type parameter here?

do you mean toggling between two images for a background or such? because clicked is not a state, pressed is 😕

I think I downloaded a wrong 1.1.60 plugin for Android Studio 3.1 because I am getting "Gradle sync failed: com.android.tools.idea.gradle.project.model.AndroidModuleModel.getSelectedVariant()Lcom/android/tools/idea/gradle/project/model/ide/android/IdeVariant; (6s 648ms)"

yes You are correct

Because the names already matches

iirc,

IDENTITY

is the default one, which means gson will convert fields whose names are exactly the same as the keys in your json object

I have all these ..kotlin_module files ranging at 2-5 kb each

Never tried JaCoCo before, but, I remembered when I want to try mockk (https://github.com/oleksiyp/mockk#2-add-class-modification-via-annotation) there’s an information if I want to use mockk with JaCoCo, I must use agent. I don’t know if this is related with your question but I hope it can help.

@Ricardo: https://kotlinlang.slack.com/archives/C0B8M7BUY/p1510675261000179 We have no problems while using kotlin and Jacoco.

I uninstalled latest kotlin plugin from android studio, I didn't find a way to download old version.

Hi, after updating the plugin to to 1.1.60 i get this error on gradle project sync: 'Gradle sync failed: com.android.tools.idea.gradle.project.model.AndroidModuleModel.getSelectedVariant()Lcom/android/tools/idea/gradle/project/model/ide/android/IdeVariant'. I can solve downgrading

Can anyone recommend a free cloud based IDE for anroid dev with kotlin support

all right problem solved forgot i was using this before we changed the response pattern from the api…

private fun providesGson(): Gson {
        val gsonBuilder = GsonBuilder()
        gsonBuilder.setFieldNamingPolicy(FieldNamingPolicy.UPPER_CAMEL_CASE)
        return gsonBuilder.create()
    }

What would be the kotlin version of this? Runnable r = new Runnable() { @Override public void run() { while (mStatus) { synchronized (this) { try { wait(1000 * 60); } catch (Exception e) { e.printStackTrace(); continue; } } sendRequest(); } } }; thread = new Thread(r); thread.start();
