[NandhiniP1]

I have refered the github sample app showing only the java code as reference and have implemented the sample in kotlin. I have shared my code fix the issue please. getting response as null only

    override fun onCreate() {
        super.onCreate()
        MobileCore.setLogLevel(LoggingMode.VERBOSE)
        MobileCore.initialize(this, LAUNCH_ENVIRONMENT_FILE_ID) {
            print("Adobe mobile SDKs are successfully registered.")
        }
        Log.d("SDKTest", "successsSDK1")
        Log.d("SDKTest", "Adobe mobile SDKs are successfully registered.")

        val decisionScope = DecisionScope("Android_Test")

        val data = mapOf(
            "__adobe" to mapOf(
                "target" to mapOf(
                    "a.profile_language" to "en-us",
                    "a.DeviceName" to "phone"
                )
            )
        )

        Optimize.updatePropositions(
            listOf(decisionScope),
            null,
            data,
            object : AdobeCallback<Map<DecisionScope, OptimizeProposition>> {
                override fun call(propositionsMap: Map<DecisionScope, OptimizeProposition>?) {
                    val proposition = propositionsMap?.get(decisionScope)
                    val offers = proposition?.offers
                    Log.d("SDKTest","SuccessssSDK2")

                    if (!offers.isNullOrEmpty()) {
                        val offerContent = offers[0].content
                        val json = JSONObject(offerContent)
                        val message = json.optString("test", "No message")
                        Toast.makeText(applicationContext, message, Toast.LENGTH_LONG).show()
                    } else {
                        Log.d("TargetOffer", "No offers found for scope ${decisionScope.name} ${propositionsMap?.get(decisionScope)}")
                    }

                    if (!offers.isNullOrEmpty()) {
                        val offerContent = offers[0].content
                        val json = JSONObject(offerContent)
                        val message = json.optString("test", "No message"+json.toString())
                        Toast.makeText(applicationContext, message, Toast.LENGTH_LONG).show()
                        Log.d("TargetOffer",offerContent)
                    } else {
                        Log.d("TargetOffer", "No offers found for scope"+offers.toString())
                    }
                }
            }
        )
    }
