开放失败：Android 12，小米11 Ultra Device上的EACCE（允许拒绝）

Question

当一个用户尝试打开具有此错误的下载的PDF文件时。

我正在使用下载manager从URL下载PDF文件。 另外，我正在使用'com.github.barteksc：android-pdf-viewer：3.2.0-beta.1'库作为PDF查看器。

除小米Mi 11 Ultra以外的所有设备都没有问题。在该型号设备中，它给出了“打开失败：EACCES（许可拒绝）”错误。下面的示例代码：

val fileName = "${File.separator}${"Presentation_Report"}${System.currentTimeMillis()}.pdf"

        fileHelper.downloadFile(url, fileName) { response, msg ->

            runOnUiThread {

                onLoadingChange(false)

                if (response.status && response.data != null) {

                    this.file = response.data

                    binding.pdfView.fromFile(response.data)
                        .onError {

                            FirebaseAnalyticsHelper.sendReportError(
                                this,
                                "Preview Activity pdf load error $url $fileName \n PDF VIEWER ERR : ${it.message ?: ""}"
                            )

                            finish()

                            fileHelper.viewFileOnError(file)

                        }
                        .load()

                } else {

                    showErrorAlert(AlertViewType.Warning, msg) { finish() }

                }

            }

        }

可变响应。数据是我们成功下载的文件。

在binding.pdfview.fromfile（response.data）中，它引发了我上面描述的错误。

我正在使用运行时权限，并且用户还启用了他手机中的所有许可。

该问题仅发生在小米Mi 11 Ultra中。

这些是我的下载文件功能和广播接收器，可在下载后接收响应。

这些是我声明的清单中使用的权限，其中是：

    <uses-permission android:name="android.permission.WRITE_CALENDAR" />

我该如何解决此问题。

有了一点挖掘，我发现了有关MI文件管理器的一些东西。但是，我不知道这与我的问题有关 有关Mi File Manager的问题
