Android Studio MediaStore Storage 无法访问文件夹

Question

尝试下载和保存文件时，会引发错误

Primary directory file not allowed for content://media/external/downloads;
allowed directories are [Download]

我该如何解决它，也许没有权限？

val multipartBuilder = MultipartBody.Builder().setType(MultipartBody.FORM)

                    multipartBuilder.addFormDataPart("oid", orderId)

                    val client = OkHttpClient.Builder()

                        .post(multipartBuilder.build())

                        }

我在 list 中声明并在我的项目中使用的所有权限的列表

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

    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.FOREGROUND_SERVICE" />
    <uses-permission android:name="android.permission.READ_PHONE_STATE" />

778线，这是

val uri = resolver.insert(
                            MediaStore.Downloads.EXTERNAL_CONTENT_URI,
                            contentValues
                        )

好像项目中用到了所有必要的权限，所以我什至不知道该用什么方法来解决这个问题

Answer 1

利用:

put(MediaStore.DownloadColumns.RELATIVE_PATH, "Download/Peshkariki")

代替

put(MediaStore.DownloadColumns.RELATIVE_PATH, "file/Peshkariki")

Primary directory file not allowed
