kotlinlang #android

Hi everyone, I've been given kind of an odd set of requirements for my latest project. I need to have RocketChat's open source app run inside the app that I am building. I am really not sure how I should approach this, but it sounds like actual changes to the rocketchat functionality will be very minimal - potentially just some resource customization. Any suggestions on where I should start?

app: 'androidProcessor' dependencies won't be recognized as kapt annotation processors. Please change the configuration name to 'kapt' for these artifacts: 'com.android.databinding:compiler:3.0.0-beta5'.

I’m testing on several devices at the moment, and so far 10'ish devices work fine, but on a Samsung device running 4.1.2, when installing from Android Studio i get a “java.lang.UnsatisfiedLinkError” on app start. It has this line in the stacktrace: ” at com.android.tools.profiler.support.ProfilerService.<clinit>(ProfilerService.java:41)” This made me think AS might be the cause, so i assembled the app from terminal, and installed it manually via ADB, and then it works completely fine. So AS is the cause of this issue. Has anyone encountered this before, and if so, any way to fix it?

Hi guys, I am trying to use mock-maker-inline to allow mocking of kotlin classes with mockito ( https://github.com/mockito/mockito/wiki/What's-new-in-Mockito-2#mock-the-unmockable-opt-in-mocking-of-final-classesmethods ) But then I am having issues with old tests. So, when I try to do something like

verify(adapter).notifyItemMoved(0, 0);

where

adapter

RecyclerView.Adapter

I am getting error this error might show up because you verify either of: final/private/equals()/hashCode() methods. Did anyone had similar issue ?

thoughts on using

instead of dagger

09/12/2017, 5:47 PM

there's no actual dependency injection

hey - guys so we are beginning to refactor a LARGE project into kotlin. Wanted to ask general rules of thumb for 3 things : RxJava, Dagger and Architecture Components. Do you guys use them in the Kotlin world, or is there something built-in that's a better/idiomatic alternative ?

Anyone know if it's possible to have the 'default new activity animation' on a fragment? EDIT: stackoverflow is extremely unhelpful for this question https://stackoverflow.com/search?q=fragment+slide+up

Any way to add a static field to an object expression? Attempting to make an anonymous parcelable...

Just looking for the shortest way of implementing Parcelable and I found @Parcelize, so I need help in converting my data class into parcelable data classes:

Copy code

data class SiteResponse(@SerializedName("result") val result: String,
                        @SerializedName("freason") val freason: String,
                        @SerializedName("site") val siteList: ArrayList<SiteObject>) {

    inner class SiteObject(@SerializedName("name") val name: String,
                           @SerializedName("short_name") val shortName: String,
                           @SerializedName("id") val id: Int,
                           @SerializedName("country_id") val countryId: Int,
                           @SerializedName("region_id") val regionId: Int,
                           @SerializedName("province_id") val provinceId: Int,
                           @SerializedName("city_id") val cityId: Int,
                           @SerializedName("latitude") val latitude: String,
                           @SerializedName("longitude") val longitude: String)
}

sorry, I misread your dependnecies, you still need rxandroid to have an access to AndroidSchedulers

Hey all. I'm a intermediate Android developer, a couple of my own small apps. I want to learn Kotlin. Has anyone used the book Android Development with Kotlin? It's fairly new and I'm trying to decide between that and Kotlin in action.

extension property is pretty constraining, because you may want to pass callback, transformations etc. With function, you can make parameters with default values but with property you are done
