为什么“ACCESS_COARSE_LOCATION”和“ACCESS_FINE_LOCATION”给我错误？

Question

我试图通过阅读文档、使用 AI 并构建最基本的请求权限应用程序来更好地理解权限，以便我可以更好地分析它，但我收到了“ACCESS_COARSE_LOCATION”和“ACCESS_FINE_LOCATION”未解析参考的错误我的代码中到处都是，但我不明白。我已经在清单中声明了它们，所以不应该有错误。 这是代码：

class MainActivity : ComponentActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContent {
        PermissionsTheme {
        Surface( modifier = Modifier.fillMaxSize()
        ){
          val context = LocalContext.current
          val requestPermissionLauncher = rememberLauncherForActivityResult(
             contract = ActivityResultContracts.RequestMultiplePermissions() ,
             onResult = {permissions ->
                if(permissions[Manifest.permission.ACCESS_COARSE_LOCATION] == true
                   && permissions[Manifest.permission.ACCESS_FINE_LOCATION] == true){
                   ...
                }else{
                   val rationaleRequired = ActivityCompat.shouldShowRequestPermissionRationale(
                       context as MainActivity,
                       Manifest.permission.ACCESS_FINE_LOCATION
                       ) || ActivityCompat.shouldShowRequestPermissionRationale(
                          context as MainActivity,
                          Manifest.permission.ACCESS_COARSE_LOCATION
                          )
                       if(rationaleRequired){...}else{...}}})
                Column() {
                Button(onClick = {
                    requestPermissionLauncher.launch( arrayOf(
                         Manifest.permission.ACCESS_FINE_LOCATION,
                         Manifest.permission.ACCESS_COARSE_LOCATION ))}) {Text(text = "Get Location")}}}}}}}

这是我的清单：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools">

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

    <application

我的代码中到处都出现“ACCESS_COARSE_LOCATION”和“ACCESS_FINE_LOCATION”未解析引用的错误

这表明您缺少常量的导入：

import android.Manifest
