hi all, all day i have been struggling to get a new activity to load from a recycleview custom adapter, i have a click listener within the customadapter but i am unable to get any further

i can get it to work from the mainactivity.kt but not from CustomAdapter.kt , startActivity() isnt there

The error i get is “cycling dependency detected error.NonExistentClass is injected at” and the location it is injected at is where i bind Interface.Factory so more or less is seems like the Implementation.Factory class becomes NonExistentClass in the incremental build for some reason.

hey guys. In an android module, in a kotlin file, I am accessing a java class from a jar and Android Studio is showing me the error "Cannot access class X : Check your module classpath for missing or conflicting dependencies". The code builds and runs ok but I keep seeing this error in the IDE. Any help? (android studio 2.3)

Does anyone know where to report issues like this. I haven't found an issue tracker for kapt yet. Is it just shared with the kotlin one?

@ankitdroiddeveloper Particulary for your view it would be look like:

class FreeView @JvmOverloads constructor(
  context: Context, 
  attrs: AttributeSet? = null,  
  defStyleAttr: Int = 0
) : View(context, attrs, defStyleAttr) {
    init {
       // Your code to init view
    }
}

what is the best way to implement a Singleton pattern in Kotlin ?

Depends what object it is.. With view objects you can kill the memory pretty fast.

orms are bad

Room or SQL Delight

you query

User

on a background thread, post it to the main thread to display, and then attempt to traverse a relation

Room and SQL Delight are object mappers–no relational mapping

threads are worse than ORMs

ORMs are fine on the server where you have threads you can block

So Dagger it is

About the second question, I was thinking about an internal project to get them used to the idea (something that could be used by the company). Any better ideas?

1) Am I testing wrong if I am trying to mock data classes in kotlin? 2) If the answer for first question is no, I am having issues mocking it with Mockito 2 even after following this article by Haidi hariri. http://hadihariri.com/2016/10/04/Mocking-Kotlin-With-Mockito/ Do I have to do something on top of it?

has anyone tried Things yet? should there be another channel for it? would love to port one of the tutorials to K…

I am trying IO operation in IntentService at onHandleIntent method but it is not guarantee to call every time and many times skip network call. Can anyway handle network call in background ?

Hey Guys did anyone have issues in adding @OnClick annotation for kotlin activity using butterknife it doesn't look like the listener getting called

call its methods to control the style, just like you would in Java: https://developer.android.com/reference/android/widget/TextView.html

is there?

has anyone seen this https://www.appbrain.com/stats/libraries/details/kotlin/kotlin?

4.40% of top 500 apps use kotlin

how i can initialized var in interface?

well, both! https://github.com/gildor/kotlin-coroutines-retrofit

a problem with that, though, is that calling

await()

also triggers the request. you need to way to trigger both requests at once and then await on both. I don't know how to do it off-hand and without trying it myself. You can try asking in #coroutines though.
