@Paul Woitaschek whats the point, build perf?

Hello ,there is any specific way to take a photo and save it with specific name for example temp.jpg??

If i didnt metion ...first I try anything which I find in stackoverflow and in other sites

-.js

We are getting a very strange bug. Anybody had a similar experience? https://stackoverflow.com/questions/52927675/static-final-field-is-null-when-it-shouldnt

Oh, right, you need album id to fetch photos, I didn't notice, sorry

something like

fetchAlbums().flatMap { album -> fetchPhotos(album.id).map { photos -> album to photos } }

would give you a pair of album / photos

I tried above code, unfortunately, I can’t get reference to

dialog

in my

onClickListener

. Do you have any idea how to solve it?

Hello I an activity with two buttons. First I take a photo and in override onactivityresult I upload the photo in firebase and I get an url which I save to photoUrl . Then in the other btn listener inside oncreate I want to use this variable but I get null as I define it in the begin of the class. How can I get the value of photoUrl which I want? https://gist.github.com/spartakos87/e0d492c7f2a9af76638bb50d05a30a46

i'm having a nice infinite loop 😥

can anyone send custom camera2 tutorial?

I heard from a level 5 engineer at Google today “The use of reactive programming is ill-advised in Android development because of known issues that it generates in the area of lifecycle complications/potential leaks. Also, Kotlin is supported as a first class language largely as a shorthand for those who prefer it when writing third-party applications” This is his argument on why we should move our application to framework and use java/native code only. @jw is this the reason why we wont be seeing Kotlin support in AOSP anytime in the future?

So many things to unpack there: - Their thoughts on reactive programming show a large gap in knowledge. All of Android is reactive programming since everything is callback and lifecycle-based and yes it can cause leaks. Android has forced reactive programming to be the only viable solution because of it's lifecycle and callbacks models and thus forced leaks on itself. Whether you choose to deal with it manually, with coroutines, with Rx, or with something else is irrelevant. Those are just higher-level abstractions. You cannot write an Android app without reactive programming principles since nearly everything on the system is asynchronous. I suspect they're just an RxJava hater. - Kotlin was definitely supported primarily for third-party applications. Google's first-party apps are generally irrelevant since they use a bespoke build system and bespoke suite of libraries unlike how normal apps are developed. I know a lot of people like to base decisions on whether Google uses things, but they represent 0.01% of the Android developer ecosystem and so they contribute 0.01% to decisions made. I would recommend ignoring them. That being said, there's already first-party apps using Kotlin and work is being done to support more. The Bazel team is developing Kotlin rules in the open on GitHub if you're interested. I suspect they're just a Kotlin-hater. - AOSP is big so "Kotlin support in AOSP" is ill-defined. Support for Kotlin was added to the (yet another bespoke) build system of AOSP a year ago. I don't know if any packages are using it or not. It's definitely being used in some of the tooling. And of course, the AndroidX libraries are developed in AOSP and they have a ton of Kotlin in them. If you're talking about the framework, it doesn't really make sense to put Kotlin in the framework as it would lock the standard library to that version and we would have the same problem we do with other platform APIs. And if you jarjar it out of the public package, then what advantage are you bringing?

can I self reference in the let block?

@greybeard1123 just for my curiosity… what is a Level 5 Engineer at Google? Is that better than a Level 1? Are there Level 42 Engineers? (while this may sound a humorous D&D-ification, I’m not a Google-yte, so I honestly don’t have a clue how to put the Level 5 in context)

I can’t seem to find an example of a when statement with int ranges. Like when(myInt) { 0..1 ->{doStuff()}}

lmao that comment about rx, whats next, dont write unit tests because only bad devs make bugs? 😄 rx is amazing, general android app code is much better because of it, and actually handles much more, where before race conditions would be yolo and only fixed when bugs reported etc. or doing stuff from callback of something else, that needs certain conditions to happen. before this would be if !conditionsOk return, and yolo most of the time

Hello there! do you know if there are specific Kotlin options to show logs in Android? With Java, I used to use Timber but I'd like to know if there are more "Kotlin" options. Thank you.

Hello,please help 😞 I am beginner.How do I fix it? Thanks https://hastebin.com/puxuxabosa.cpp

What is the recommended online course to start Kotlin, for experienced Android developers?

The kotlin plugin was broken in the Android studio 3.4 canary2 built with 183.2

Hello guy What is the best way to every 2 minute send a request to server to get latest data ?

Hello, since I've updated to kotlin v1.3.0-rc, the android studio IDE doesn't recognize

kotlinx-android-extensions

. I'm using Android Studio v3.2.1 (Build #AI-181.5540.7.32.5056338). If I comment out the plugin, then sync, then un-comment, and resync, the plugin works again. Any idea how I could solve that?

ProgressDialog is deprecated then what is the best way thinking in ux to help users about an action. I am talking about a register form for example. Thanks !!

not everyone is using Fragments, which is what the probably had in mind when deprecating it

what is your

single

declaration in your module? If you’re doing

single<ComponentA>()

, I would change it to

single { ComponentA(get(), get()) }

. Omitting parameters and having koin find them is experimental. As far as I can tell from the source code its based on reflection https://github.com/InsertKoinIO/koin/blob/e159f2dd845990a9b5588d142692d132d7597708/koin-projects/koin-core/src/main/kotlin/org/koin/core/instance/InstanceHolder.kt Here’s a Retrofit example in my app

val networkModule: Module = module {
    single { createWebApi<AuthApi>(get<NetworkClient>().defaultRetrofit) }
    single { createWebApi<MapBoxApi>(get<NetworkClient>().mapBoxRetrofit) }
}
inline fun <reified T> createWebApi(retrofit: Retrofit): T = retrofit.create(T::class.java)
