Hi guys, I'm converting my android project to kotlin multiplatform and I'm running into a simulator crash when running my app. The logcat error is Failed to find HTTP client engine implementation in the classpath: consider adding client engine dependency .

My client looks like this:

private val client = HttpClient() {
        install(Logging)
        install(ContentNegotiation) {
            json(Json {
                prettyPrint = true
                isLenient = true
                ignoreUnknownKeys = true
            })
        }
    }

And my shared module (where my ktor code lives) looks like this (I'm using kotlin 1.9.20)

commonMain {
            dependencies {
                implementation(libs.ktor.client.core) // 2.3.5
                implementation(libs.kotlinx.serialization.json) // 1.6.0
                implementation(libs.kotlinx.coroutines.core) // 1.7.3
                implementation(libs.ktor.client.content.negotiation) // 2.3.5
                implementation(libs.ktor.serialization) // 2.3.5
                implementation(libs.ktor.logging) // 2.3.5
            }
        }

I didn't have an androidMain sourceSet defined so, one of the things I tried was to add one with the same dependencies as commonMain (based on a thread from 3 years ago) but that didn't help the issue go away.

Is there a different place I should be adding the engine?

The reason I'm not specifying an engine in my HttpClient() declaration is because I just wanted to use the default engine, should I be using a different engine? I had a thread about a month ago where I was using CIO but that led to issues with my ios app not running

HttpClient without a specific engine tries to fetch an engine from the classpath, specified by your dependencies. You could either use CIO or use the platform specific engine by adding the dependency.

[hfhbd]

core does not contain any engine

[Rodrigo Munera]

So I need to add an engine in my app dependencies? or still in my shared module?

[hfhbd]

It does not matter, both modules are merged in your classpath but from the module structure you only need it in your app, so app dependencies.

Got it. Thank you!
