Sorry if my question is not Kotlin 😄 I am facing with navigation component issue. I am trying to navigate to a screen inside a navFragmentContainer. It work fine but after I navigateUp (or popBackStack) I got a bank screen. Any idea for my issue, thanks!!

Hi, I am working on location based app. Right now i am giving the android 12 support. I have done with all location permission related changes. In our app we have integrated sendbird sdk for call. So when i try to call then app is crashing with

java.lang.SecurityException: Need android.permission.BLUETOOTH_CONNECT permission for android.content.AttributionSource@57f2dd45: AdapterService getBondedDevices

Even though my app does not any requirement for bluetooth related feature. Does anyone know about this exception?

Hello All, I am trying migrating my app to android 12 by changing the target SDK version to 31 in build.gradle. As required, I have added 

android:exported

 flag to every activity/receiver/services/provider tags present in my manifest file. But still I am getting this error.

Manifest merger failed : android:exported needs to be explicitly specified for <receiver>. Apps targeting Android 12 and higher are required to specify an explicit value for `android:exported` when the corresponding component has an intent filter defined.

So I am guessing this issue is due to any 3rd party library whose manifest contains a receiver without 

android:exported

 flag. I have also checked merged manifest file for missing 

android:exported

 in components of any third party libraries. But in merged manifest file also all activity/receiver/services tags has exported flag. So how can I find that missing receiver which is causing the issue.

Hi, what is the equivalent of CheckStyle for Kotlin https://checkstyle.org/index.html

Hello everyone, i'm writing unit tests in my VM using a mockk and Turbine combination but i'm facing an interesting problem in this test:

@Test
fun `Should show api error when create request token fails`() = runTest {
    every { loginRepository.createRequestToken() } returns flow {
        emit(
            Source.Error(
                NetworkError(400, "error")
            )
        )
    }

    viewModel.events.test {

        viewModel.onLoginClick()

        verify(exactly = 1) { loginRepository.createRequestToken() }
        confirmVerified(loginRepository)

        Truth.assertThat(viewModel.isButtonLoading.value).isFalse()

        Truth.assertThat(awaitItem())
            .isInstanceOf(LoginEvents.ShowApiError::class.java)

        cancelAndConsumeRemainingEvents()
    }
}

When i run this test the Truth assert that verifies the event succeeds, but mockk throws an error saying that repository,createRequestToken() wans't called

public abstract class Task<TResult> {
    public Task() {
    }


    public abstract <X extends Throwable> TResult getResult(@NonNull Class<X> var1) throws X;

    @Nullable
    public abstract Exception getException();
    
}

java getResult method how to convert to koltin code

abstract class Task<TResult> {

    @Throws(X::class)
    abstract fun <X : Throwable> getResult(var1: Class<X>): TResult

}

Hi, I'm new to android development, but I want to create an app. I found GitHub repositories useful for learning. Can you please share some good Kotlin android repositories? 🙇‍♂️

Hey guys. Can someone know how to update list in MutableStateFlow . When I am adding more value, my previous value will drop. Please someone guide me

Apologies for a probably off-topic question, but can anyone please point me towards the best practices for navigation in Android? Specifically, I'm wondering whether I should use the Navigation component or not. Also, my understanding is that Fragments are preferred over activities. So when I want to push (sorry, coming from iOS development! 🙂) a new screen, should I start a new

Intent

and host my

NewScreenFragment

in the

NewActivity

? Or is it better to just replace the

CurrentScreenFragment

with

NewScreenFragment

(and add it to back stack) in the

CurrentActivity

and then adjust the action bar (back button, menus etc)? Finally, to top it all off, I want to apply the coordinator pattern on all that so I don't tight couple the flows within Activities/Fragments. Thank you very much in advance!

Hello, if anyone uses the Macbook Air with M1 chip it is worth for Android Development.

Is there a pure kotlin library alternative for android.icu.text.StringSearch ?

Hi everyone. Once I have connected my app to a firebase project, can I change it? I mean, change the firebase project by keeping the same app.

Where can I find info about which firebase project is connected to my app? Thank you very much in advance.

Hey I am working in Android Kotlin. I am learning this LatestNewsUiState sealed class example from Android doc. I made my own 

sealed class

 example. But I am confused little bit, how can I achieved this. Is I am doing right for my scenario or not?

if I have a

sealed interface

within a

sealed interface

I can't have an exhaustive when with the outer

sealed interface

entries (see example in thread). What's the reason for this?

Something I’ve been confused about - Is certificate pinning still a best practice on Mobile? The web community has basically stopped the practice completely, and I always hate having to deal with the certificate upgrades every year or 2. Is there a better way that I’m just not informed of yet?

Hello, I'm trying to suppress optin warnings module wide by adding the compile args in my gradle file. The exact same compiler args work just fine on another project with same AS version and gradle plugin but for some reason for this project the warning doesn't go away, the app builds and runs but the warning stays. removing the optins from gradle will result in an error, so they are working but the warnings aren't removed. Here's my gradle file: https://github.com/roudikk/compose-navigator/blob/master/sample/build.gradle.kts

In the architecture guide https://developer.android.com/jetpack/guide/ui-layer/events#handle-viewmodel-events it is suggested to model navigation as state updates instead of events. It makes sense, but how to best model it in a way which avoids navigating away multiple times? On screen A the state changes in a way that signifies screen B should be shown. In response, screen A navigates to screen B. All is fine. Then the user presses back. We are on screen A, but it will just immediately navigate to screen B since the state didn't change. How to handle that?

Hello all,

private val _qualifications: MutableStateFlow<List<QualificationView>?> = MutableStateFlow(null)
val qualifications:StateFlow<List<QualificationView>?> = _qualifications

I’m trying to use qualifications between parent fragment and bottomSheet, but consumer collects list just once.  Screenshot of the code below.

Hey I am working in json response with html tag in kotlin. I don't understand how to parse html tag in response. I tried to work with retrofit and moshi. My response will look like this

Hi, I have the stupidest question on creating a simple data structure in Json format! Im somewhat confused when i tried creating it via mutableMapOf.. mutableListOf etc and the output is not like below. Anybody knows a simple kotlin magic to create this output:

[

{

"type" : "food",

"value" : "pizza, buger, pasta"

},

{

"type" : "drink",

"value" : "soda, Mountain Dew, redbull"

}

]

Hi I have a kotlin data class, initially it had 200 parameters in constructor and was working fine, at some point I got it updated as the data is coming from server and I need to add as many new parameters gets added to one JSON object and then I did. But as soon as parameters increased to 300 it started giving error like Bad class exception I am now somewhat confused. So to overcome this i created a plain POJO class in Java and it is working fine. Is there any documentation or solution I apply and use kotlin data class instead of POJO Am I missed something? Currently my server returning more than 500 strings in one JSON object

I have scenario like this:

data class A(
    val metadata: String
){
    data class B(
        val metadata: String
    )
}

fun updateData(data: Any){
    when(data){
        is A -> {// update A metadata value
        }
        is A.B -> {// update B metadata value
        }
    }
}

want to update the value of

metadata

for both data class by using the same logic and don't want to write it twice inside when statement. How can I do it by writing the logic only once?

I want to add applicationIdSuffix for staging buildtype like this

staging {
    applicationIdSuffix ".staging"
}

but I am getting this error

Caused by: org.gradle.api.GradleException: No matching client found for package name

I can fix this by creating seperate sourceSets and put seperate google_services.json files in them. Now I don't want to create seperate sourceSets for staging and prod build types. Can anyone suggest me a solution to this?
