从DownloadManager下载的音频文件未反映在Android Q的MediaStore中

Question

我正在使用DownloadManager下载音频文件

    val token = getAccessToken()
    val request = DownloadManager.Request(uri)
        .addRequestHeader("Authorization", "OAuth $token")
        .setDestinationInExternalPublicDir(Environment.DIRECTORY_MUSIC, fileName)
        .setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED)
    request.allowScanningByMediaScanner()
    val downloadManager = context.getSystemService(Context.DOWNLOAD_SERVICE) as DownloadManager
    downloadManager.enqueue(request)

，但下载的文件未反映在MediaStore中。我知道在Android 10中不建议使用allowScanningByMediaScanner（）。有没有其他选择？

下载完成后，请尝试以下操作：

val toBeScanned = arrayOf<String>(musicPath) MediaScannerConnection.scanFile( this, toBeScanned, null ) { path, uri -> println("SCAN COMPLETED: $path") }
