Help in retrieving the string value from key

[Takashi-san]

Hi, I've been trying to use the string resource on the iOS side but I'm always getting back the string key instead of its value. Ways that I have tried to access the resource:

// key = my_key, value = "my text"

let resource = MR.strings().my_key
// log: dev.icerock.moko.resources.StringResource@1ca6668

NSLocalizedString(resource.resourceid, bundle: resource.bundle, comment: "")
// return: "my_key"

MokoUtils.companion.getStringDesc(resource: resource).localized()
// return: "my_key"

MokoUtils.companion.getString()
// return: "ResourceStringDesc(stringRes=dev.icerock.moko.resources.StringResource@1ca6668)"

The MokoUtils on android side:

class MokoUtils {
    companion object {
        fun getStringDesc(resource: StringResource) : StringDesc {
            return StringDesc.Resource(resource)
        }

        fun getString() : String {
            return StringDesc.Resource(MR.strings.my_key).toString()
        }
    }
}

I believe that it was unable to find my bundle according to what I saw in other issues and the log of resource.bundle. I tried to load the bundle but it never loaded.

resource.bundle
// log: </Users/myUser/Library/Developer/CoreSimulator/Devices/B91029C6-D738-452A-8646-CAECFE8798C8/data/Containers/Bundle/Application/515C8A5B-EBBF-440D-BD49-C8A4A41A1A9F/MyApp.app/android:shared_core.bundle> (not yet loaded)

Maybe some configuration of my project isn't right, but I can't figure out what is it that is wrong. Android project build.gradle:

Any help now is greatly appreciated.

seems that all configured ok. can you show contents of compiled framework and app? run ls -lR . inside compiled app and compiled framework

What are you looking for in the compiled app path? If I try to run this on the android/app/build folder the log is too big and I can't share it.

[Alex009]

in compiled app i see that bundle with resources exist and should correctly read. please try to configure reproducer from sample of moko-resources
