Application is crashing when using koin outside SDK

[MANISH9912]

Application is crashing when trying to access koin from SDK

• I have been developing SDK where I'm using Koin as DI in that SDK.
• I'm able to run the app successfully from other module in the same app.
• However, if I try to use it from other Android project, application is crashing.
• I'm using SDK in the form of aar format.

**Here are my code snippets

SDK Koin initiation code:

object FeedbackSDK {

fun init() {
    startKoin {
        modules(feedbackModule)
    }
}

}

Dependenies

implementation(project.dependencies.platform(libs.koin.bom))
implementation (libs.koin.android)
implementation (libs.koin.androidx.compose)
implementation (libs.koin.navigation.compose)
implementation(libs.koin.core)

libs.toml

koin-android = { module = "io.insert-koin:koin-android", version.ref = "koin" }
koin-androidx-compose = { module = "io.insert-koin:koin-androidx-compose", version.ref = "koin" }
koin-bom = { module = "io.insert-koin:koin-bom", version.ref = "koin" }
koin-core = { module = "io.insert-koin:koin-core", version.ref = "koin" }
koin-navigation-compose = { module = "io.insert-koin:koin-compose-viewmodel-navigation", version.ref = "koin"}

Accessing Koin outside of SDK:

FeedbackSDK.init() // Inside application onCreate

Please help here.

NoClassDefFoundError means a problem of linking your library here. As embedded Koin, I would suggest to target the most recent stable version.
Do you provide your lib as fat jar?
