I m building a Kotlin application (for Android). I need to convert GSON in Object.
This is the content of my FuelJSON:
{"status":1,"message":"Ok","result":[{"devices":[{"id":2,"name":"Zephyr","description":"Zephyr","brand":"Zephyr","macaddress":"A0:E6:F8:EF:F7:44","rotationTime":60,"parametri":[{"idParameter":1,"parameter":"Battito cardiaco","syncWs":true,"syncMqtt":false},{"idParameter":2,"parameter":"Frequenza respiratoria","syncWs":true,"syncMqtt":false},{"idParameter":3,"parameter":"Postura","syncWs":true,"syncMqtt":false},{"idParameter":4,"parameter":"Temperatura","syncWs":true,"syncMqtt":false},{"idParameter":5,"parameter":"ECG","syncWs":true,"syncMqtt":false},{"idParameter":6,"parameter":"RR","syncWs":true,"syncMqtt":false},{"idParameter":8,"parameter":"Attività Fisica","syncWs":true,"syncMqtt":false}]}],"defaultParameter":{"invioDatiWS":true,"tempoInvioDatiWS":60,"invioDatiMqtt":false,"tempoRotazioneZephyr":600,"tempoScansioneZephyr":60,"tempoRotazioneDosimetro":60,"tempoScansioneDosimetro":20,"tempoRotazioneBeacon":60,"tempoScansioneBeacon":25}}]}
This is the code:
ApiHandler.getInstance().deviceList(devRequest) { deviceListJSON ->
Log.i(TAG,"device scaricati " + deviceListJSON.toString());
var mUser = Gson().fromJson(deviceListJSON.toString(), DeviceConfiguration::class.java)
}
This is the DeviceConfiguration class:
package model.dataModel
import android.graphics.Bitmap
import kotlinx.serialization.descriptors.PrimitiveKind
import java.io.Serializable
data class DeviceResponse(
val status: String,
val message: String,
val result: List<DeviceConfiguration>
)
data class DeviceConfiguration(
val id: Int,
val nome: String,
val descrizione: String?,
val distanza: Double?,
val livelloDifficolta: String?,
val alititudineMax: Double?,
val alititudineMin: Double?,
val tipoPercorso: String?,
val tempoInMovimento: Int,
val tempoTotale: Int,
val dislivello: Double?,
val devices: List<Dev>,
val defaultParameter: DefaultParameter,
) : Serializable
data class Dev(
val id: Int,
val name: String,
val description: String,
val brand: String,
val macaddress: String,
val rotationTime: Int,
val parametri: List<Parametri>,
): Serializable
data class Parametri(
val idParameter: Int,
val parameter: String,
val syncWs: Boolean,
val syncMqtt: Boolean
): Serializable
data class DefaultParameter(
val invioDatiWS: Boolean,
val tempoInvioDatiWS: Int,
val invioDatiMqtt: Boolean,
val tempoRotazioneZephyr: Int,
val tempoScansioneZephyr: Int,
val tempoRotazioneDosimetro: Int,
val tempoScansioneDosimetro: Int,
val tempoRotazioneBeacon: Int,
val tempoScansioneBeacon: Int
): Serializable
This is the error:
