Problem Describe

使用

val task = DownloadTask.Builder(cacheUrl, parentFile, filename)
                    .setFilename(filename)
                    // the minimal interval millisecond for callback progress
                    .setMinIntervalMillisCallbackProcess(100)
                    // ignore the same task has already completed in the past.
                    .setPassIfAlreadyCompleted(false)
                    .setConnectionCount(1)
                    .build()
                DownloadSerialQueue.enqueue(task)

安卓系统中下载文件时创建一个与下载文件相同大小的临时文件，是为了确保下载过程的安全性、数据完整性以及文件系统的稳定性。这种做法在大多数情况下能够有效地保护用户数据和提供良好的用户体验。
