  <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
    <!--Android 10以上 权限适配-->
    <uses-permission android:name="android.permission.MANAGE_EXTERNAL_STORAGE" />

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:requestLegacyExternalStorage="true" 
        android:supportsRtl="true"
        android:theme="@style/Theme.AndroidProGuard"
        tools:targetApi="31">
        <activity
            android:name=".MainActivity"
            android:exported="true">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />

2. MainActivity请求权限

// 工具类配置
Utils.init(this)

// 请求权限
private fun requestFilePermission() {
        when {
            Build.VERSION.SDK_INT >= Build.VERSION_CODES.R -> {// Android 10以上
                if (!Environment.isExternalStorageManager()) {
                    AlertDialog.Builder(this)
                        .setTitle("提示")
                        .setMessage("开启文件访问权限！")
                        .setNegativeButton(
                            "取消"
                        ) { dialog, _ ->
                            dialog.dismiss()
                        }
                        .setPositiveButton("前往") { dialog, _ ->
                            dialog.dismiss()
                            startActivity(Intent(Settings.ACTION_MANAGE_ALL_FILES_ACCESS_PERMISSION))
                        }.create().show()

                }
            }
            Build.VERSION.SDK_INT >= Build.VERSION_CODES.M -> {// Android 6以上
                if (!PermissionUtils.isGranted(
                        Manifest.permission.WRITE_EXTERNAL_STORAGE,
                        Manifest.permission.READ_EXTERNAL_STORAGE
                    )
                ) {
                    PermissionUtils.permission(
                        Manifest.permission.WRITE_EXTERNAL_STORAGE,
                        Manifest.permission.READ_EXTERNAL_STORAGE
                    ).callback { isAllGranted, _, _, _ ->
                        if (!isAllGranted) {
                            ToastUtils.showShort("没有开启文件权限")
                        }
                    }.request()
                }
            }
            else -> {}

    private fun getExternalStorageDirectory(): String? {
        val extFileStatus = Environment.getExternalStorageState()
        val extFile = Environment.getExternalStorageDirectory()
        // 判断是否处于挂载状态
        if (extFileStatus == Environment.MEDIA_MOUNTED && extFile.exists() && extFile.isDirectory
            && extFile.canWrite()
        ) {
            return extFile.absolutePath
        }
        return null
