Is there a setup guide for using Intellij with Capacitor/Typescript projects? The project loads and Intellij recognizes that there is an android component, but there are settings I’m not sure about. The docs discuss setting up Typescript projects, but don’t seem to address Capacitor/Typescript specific apps.

Just wondering if anyone knows how to test this scenario?

fun someFunctionInsideActivity() {
    val intent = try {
        packageManager.getLaunchIntentForPackage("some.app.id")
    } catch (e: Exception) {
        Intent(
            Intent.ACTION_VIEW,
            Uri.parse(webSiteUrl)
        )
    }
    startActivity(intent)
}

I want to write

Espresso

test for both scenario. I was wondering if its possible to Mock the return of

packageManager.getLaunchIntentForPackage(...)

so that I could test both scenario in test. Any ideas? Any other way of testing this would be appreciated. Thanks in advance.

I'm wondering if this lambda use creates a potential memory leak:

class SomeFragment: Fragment() {
    
    val myVal: SomeClass by lazy { 
        SomeClass { requireContext().packageName }
    }

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        myVal.runLambda()
        
    }
}

class SomeClass(
    private val willBeRunSomeTimeInTheFuture: () -> String) {
    
    fun runLambda() {
        Thread.sleep(1000)
        println(willBeRunSomeTimeInTheFuture())
    }
}

Trying to wrap my head around if I have to worry when using

requireContext

in a lambda that might get executed at a point the fragment is potentially already gone again, and what to do about it. If this is problematic (happy to hear why exactly), would a

WeakReference

be enough to mitigate this, like below?

WeakReference(requireContext()).get()?.packageName ?: ""

Or do I completely misunderstand something here? Let me know if this example or my question is not sufficient to understand the problem.

Help guys! I want to pass a network call to this function but I couldn't:

suspend fun <T> wrapNetworkCall(call: () -> T) : NetworkResult<T> {
    return try {
        NetworkResult.Success(call())
    } catch (e: HttpException) {
        if (e.code() == 400)
            NetworkResult.BadRequestError(e)
        else NetworkResult.Error(e)
    }
}

coroutineScope.launch {
    val result = wrapNetworkCall {
        Api.retrofitService.getCurrent() // Suspension functions can be called only within coroutine body
    }
}

[SOLVED] I have a problem with generics:

fun <T : ResponsePacket> subscribe(..) : Flow<T> {
    val packet = ResponsePacket()
    emit(packet as T)
    println("what is T: ${packet.javaClass}") // prints ResponsePacket
}

caller side:
dao.subscribe<ParameterResponsePacket>()

The IDE marks the packet as smart casted (green background) but it isn't actually. Any ideas whats is wrong?

Hi Guys

Anyone if can help with Android studio errors

Hello. I have an issue from migration from groovy to kts for my build.gradle. I dont understand how to use a plugin in my `build.gradle.kts`file.

build.gradle.kts

which works:

I'm also interested in knowing the solution for this. You may get a better response for this if you ask in the #compose channel. Do you mind posting this there as well?

Hey, I have noticed many of android components does not have proper customization possibilities so i started rewriting them from scratch. Here is my first component library for NumberPicker: https://github.com/Stonks-tech/GoodPicker And some example of DrawablePicker. Please take a look and let me know if recreating such components (CalendarView coming next) will be useful for you

I have a long string. Is there a neat way to get the whole word for a given index in that string? It should respect all common delimiters (whitespaces, comma, question mark,...).

Is anyone here from Southern California (Orange County, LA, or San Diego)?

Do you have any experience of using a remote logging system? I am confused about what to choose. I can upload logs to firebase firestore/relatime db, use firebase analytics, or use another provider. What do you think?

Simple Android Question: When we want to check network connectivity in Android, connectivity manager has API of checking capability. Should we… • Get all available networks and then check each network’s capability and if any network has internet capability and if any network has capability then return true • Get active network, check if it has network capability or not What should be the approach and what will be the behaviour difference with both the approaches?

you can use the

Scaffold

API for that. The

content

lambda receives a

PaddingValues

which you can use to retrieve the padding of both top and bottom bars which are provided to the

Scaffold

Having a Compose for desktop app where a UI-input triggers the load of images from online resources. The loading is done in a coroutine. As long as the UI is triggering new loads, the not yet resolved loading shall be canceled, so that only the last call will be executed. Not sure if I got the coroutine cancellation stuff right, it works as expected, but is there a better way? Thanks for thoughts.

private val modelScope = CoroutineScope(SupervisorJob() + <http://Dispatchers.IO|Dispatchers.IO>)

fun loadImageBitmap(id: Int) {

if (currentId == id) {

return

}

currentId = id

modelScope.coroutineContext.cancelChildren().also { print(".") }

//cancel all requests before the current one - prints a dot each just for demonstrating

modelScope.launch { //Coroutine #1

delay(500) //simulate longer http request

println("\njob ${this.coroutineContext.job.hashCode()} gets Image $id")

currentImage = withContext(<http://Dispatchers.IO|Dispatchers.IO>) {

URL("$baseUrl$id-1.jpg").openStream()

}

.buffered()

.use(::loadImageBitmap) // loads image

}

}

is the the correct way to determine whether or not my library code is being executed in a debug build?

val isDebuggable = 0 != applicationInfo.flags and ApplicationInfo.FLAG_DEBUGGABLE

I tried using

BuildConfig.DEBUG

but thats always false
