Question

我每次尝试运行应用程序时都会收到此错误

build.gradle(project):

buildscript {
ext.kotlin_version = "1.4.31"
ext.nav_version = "2.3.0"
ext.groupie_version = "2.3.0"

ext.gradle_version = '4.0.2'

我尝试了近两天的很多解决方案，仍然遇到同样的问题..出了什么问题？

应用程序运行良好，但在我添加了一些文件后，我遇到了这个问题

我尝试重命名文件（可能是因为名称是“Zone”而导致此问题） 我试图改变 kotlin_version 但没有解决这个问题

根据要求，这里是 StateZone 文件：

import com.google.gson.annotations.SerializedName
data class StateZone (

@SerializedName("zone") val zone : String,
@SerializedName("start") val start : String,
@SerializedName("end") val end : String,
@SerializedName("locations") val locations : List<String>,
@SerializedName("prayer_times") val prayer_times : List<Prayer_times>
)

这里是 PrayersManager：

class PrayersManager
private constructor(
@ApplicationContext private val context: Context
) {
var con:Context
var settings:Settings
val praysNames:Array<String>
lateinit var locale: Locale
lateinit var geocoder: Geocoder
private val is24Format = DateFormat.is24HourFormat(context)
private val dispatcher = Dispatchers.IO
private lateinit var countDownTimer: CountDownTimer
val countDownPrayerTime: LiveData<String> = MutableLiveData()
val viewPrayersLive : LiveData<ArrayList<Pray>> = MutableLiveData()
val todayPrayersLive : LiveData<ArrayList<Pray>> = MutableLiveData()
val nextPrayLive: LiveData<Int> = MutableLiveData()
val countryName: LiveData<String> = MutableLiveData()
val stateName: LiveData<String> = MutableLiveData()
