I'm very excited to learn about Apple Pickle and I just following the documentation of configuration for kotlin and example for config-kotlin,

I have SoldierConfig at my resources.

This is my SoldierConfig.kt

package example

import org.pkl.config.java.Config
import org.pkl.config.java.ConfigEvaluator
import org.pkl.config.kotlin.forKotlin
import org.pkl.config.kotlin.to
import org.pkl.core.ModuleSource

class SoldierConfig {
    private val config: Config = ConfigEvaluator.preconfigured().forKotlin().use { evaluator ->
        evaluator.evaluate(ModuleSource.modulePath("SoldierConfig.pkl"))
    }
    private val soldier = config.to<Soldier>()

    fun getBandungConfig() : Soldier.SoldierRequirement? {
        return soldier.soldierConfigs.getOrNull(0)
    }
}

I call the class at MainActivity.kt, like this

override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        val soldierConfig = SoldierConfig()
        val requirementBandung = soldierConfig.getBandungConfig()
        println("reqBandung: minAge is "+requirementBandung?.minAge)
        
}

I'm successfull on code generation and run it at main() fun, but failed when access the config from the class in app with error

Please help me, what's wrong and how to solve it?

@StefMa commented on GitHub (Feb 22, 2024):

Path.of() was added in API 34. Make sure your phone runs in this version. Then it might work 😉

Otherwise you could try using desugaring
= https://developer.android.com/studio/write/java11-nio-support-table
It seems this brings also support for older android versions.
