这是一个有点不方便的情况;然而，由于这段代码，我们遇到了DownloadManager.STATUS_PAUSED错误（原因日志是 * 下载失败：1*）.我发现了相关信息从这个链接：DownloadManager.尽管遇到了这个错误，有关它的文档也是相当不足.我只是添加了这样一个方法来检测问题的原因.

val downloadId = downloadManager.enqueue(request)
lifecycleScope.launch {
    while (true) {
        checkDownloadStatus(applicationContext, downloadId)
        delay(10000)
    }
}
private fun checkDownloadStatus(context: Context?, downloadId: Long) {
    val downloadManager = context?.getSystemService(Context.DOWNLOAD_SERVICE) as DownloadManager
    val query = DownloadManager.Query().setFilterById(downloadId)
    val cursor = downloadManager.query(query)
    if (cursor.moveToFirst()) {
        Log.i("DownloadManager", "cursorStarted")
        try {
            val columnStatusIndex = cursor.getColumnIndex(DownloadManager.COLUMN_STATUS)
            val columnReasonIndex = cursor.getColumnIndex(DownloadManager.COLUMN_REASON)
            val status = cursor.getInt(columnStatusIndex)
            Log.i("DownloadManagerStatus", "$status")
            when (status) {
                DownloadManager.STATUS_SUCCESSFUL -> {
                    Log.i("DownloadManagerSuccess", "Download successful")
                }
                DownloadManager.STATUS_FAILED -> {
                    val reason = cursor.getInt(columnReasonIndex)
                    Log.e("DownloadManagerFailed", "Download failed: $reason")
                }
                DownloadManager.STATUS_PAUSED -> {
                    val reason = cursor.getInt(columnReasonIndex)
                    Log.e("DownloadManagerPaused", "Download paused: $reason")
                }
                else -> {
                    val reason = cursor.getInt(columnReasonIndex)
                    Log.e("DownloadManagerUnknown", "unknown : $reason")
                }
            }
        } catch (e: Exception) {
            e.printStackTrace()
        }
    }
    cursor.close()
}
