kotlinlang #android

Hi guys, What approach do you use when you have a feature with several steps ? where these steps are fragments. Do you use a viewmodel for each fragment or a sharedViewModel for all fragments?

I am working with a project that has a

buildSrc

directory which I’ve cleaned up and no longer need right now, but i still see it being built on every ..build, I cannot seem to find the directive that is letting gradle know that it needs to do this, i would like to stop doing this, how can I?

I am working on a sample of a multimodule project: Aurora. But, while using the Navigator module I am facing:

'navigator:kaptGenerateStubsDebugKotlin FAILED'

error. I am really blocked and could not move forward due to the Gradle error. The full logs:

Good morning. In a journey to extinguish XML I dived into an adventure of localizing my code using kotlin instead. Everything started with a curious Swift code that did something like "string".localize. This really excited me. But I will appreciate some feedback from Android seniors about taking downs this road and problems that will kick me in the butt too late to avoid doing a major refactor. Feedback will be much appreciated. For a World with more Kotlin.

An observation about the context of context warning tags I've seen around the Kotlin community. This allows very unhelpful people to come and tag context as if didn't belong there without any helpful information/feedback of the why this is happening. This is a people repellent, if you want to be helpful and improve general behavior, be informative about the tag you added to someones post or just don't. I know this brings you this little satisfaction of doing something but you are not helping anything but your ego. People don't share a the same understanding you believe it's "common".

Hi All, I'm trying to run a Ktor server on android but cannot get the static webpage to display on the browser. I've added an assets folder and place the website as a subfolder in it, The request is recognized but the path I give in the response always seems to be wrong. Any ideas what I'm doing wrong?

Probably more of an AndroidStudio question... but... This expression:

Base64.decode("eF4Nzr1NBDEQQGEjQXot3FZw8nj8mxIcyUIAghTNeMawWsHB7SJ0HVABvdEANRDi_HvSO9s-0ki3o77vp7s8PrT7WU_m_Pfv5-v7Qj7UbKyiUCGEQiASLETHDBI4i8ekIXOBVCNgspxraYKIvrYQsYSKVIEzOxsokDbffZHCyQljlqjFJ3HNN6kdFK-xiPfJZhbHVYmsBfNGy9KnwGw92F5WdMm21neeD8s6idnsrk_D5fQ07Gkdro6q83Cj6-fhOJtXelFj_gHcOkP7", Base64.NO_PADDING or Base64.NO_WRAP or Base64.URL_SAFE)

In an InstrumentTest (so runs on the device) works fine. But run it from a simple unit test (which runs on the development box--mac os in this case--i believe), and it fails. returns null every time. Gives me the heeby jeebies about relying on unit tests.

Has anyone had some issue with trying to migrating Koin from V2 to V3 and getting rid of the Jcenter dependency in the dependency. I was able to sync gradle but i am not able to recognise the io.insert-koin in my project when trying to import the same in my class. Has anyone faced a similar problem ?

Hello, I've a difficult question. I get this error 'java.lang.IllegalArgumentException: SavedStateProvider with the given key is already registered'. What is the reason?

Fragment

 private val viewModel by viewModels<AuthViewModel>()
 override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)
        binding = FragmentLoginBinding.bind(view)
        instance =this
}

fun login(): String {
    viewModel.login(clientId, partner.toString(), password)
    val clientId = binding.editTextTextEmailAddress.text.toString().trim()

    val encrypted = encrypt(clientId, publicKey)
  
    return encrypted
}

RemoteDataSource

private fun getRetrofitClient(): OkHttpClient {

    val str= LoginFragment().getInstance()?.login()

Is there a way to make use of Ktor Locations on android http client? The idea is to have shared module between android and ktor backend and thus define the routes and models only in one place

I am getting the following Kotlin warning on my circle ci build

No cast needed

i tried adding the suppress annotation but still get the same warning

@Suppress("UNCHECKED_CAST")
val viewStub = (parentBottomTabs as ViewStub)

How do i properly suppress this warning?

I'm trying to implement a facebook login flow with jetpack compose, unfortunately I'm having issues with getting

rememberLauncherForActivityResult

to hit. What I have gotten to work is to write my own activity class to handle the facebook callback and I'm able to get the token from facebook. The problem is I don't know how to pull the token out of an activity as I can't pass any callbacks into the activity... I was looking into maybe using a broad cast receiver to send the token out of the activity result back to the jetpack compose code. I'm newish to android so unsure if the broadcast receiver is the best way to do this? Is there better ways to send a string out of an activity than that?

I'm trying to implement a facebook login flow with jetpack compose, unfortunately I'm having issues with getting

rememberLauncherForActivityResult

So it looks like I should use putExtra to set a key/string pair. In my activity

override fun onSuccess(loginResult: LoginResult?) {
    val token = loginResult?.accessToken?.token
    intent.putExtra("token", token)
}

I set the putExtra to token. In my compose code I start a thread waiting for the token to be set

Thread {
    while (intent.getStringExtra("token") == "") {
        val tok = intent.getStringExtra("token")
        Thread.sleep(1000)
    }
    val token = intent.getStringExtra("token")
}.start()

I verify with break points that the token is being sent but when I set the break point back in my thread the token is never set...

Alright that didn't work either. I just used a singleton to share data between the compose and activity which worked
