BaseDownloadTask

For example: FileDownloader.create(URL).setPath(xxx).setListener(xxx).start()

You can get more readable description from here

function	description
setPath(path:String)	Absolute path for save the download file
setPath(path:String, pathAsDirectory:boolean)	If pathAsDirectory is true, the path would be the absolute directory to store the downloading file, and the filename will be found in contentDisposition from the response#header as default
setListener	For callback download status(pending,connected,progress,blockComplete,retry,error,paused,completed,warn)
setCallbackProgressTimes	Set the maximal callback count of FileDownloadListener#progress during the entire process of downloading
setCallbackProgressIgnored	Ignore all callbacks of FileDownloadListener#progress during the entire process of downloading
setCallbackProgressMinInterval	Set the minimum time interval between each callback of FileDownloadListener#progress
setTag(object)	Sets the tag associated with this task, not be used by internal
setTag(key,object)	Sets a tag associated with this task. If the key already existed, the old tag will be replaced
setForceReDownload	If set to true, will not check whether the file is downloaded by past, default false
setFinishListener	-
setAutoRetryTimes	Set the number of times to automatically retry when encountering any error, default 0
setSyncCallback	if true will invoke callbacks of FileDownloadListener directly on the download thread(do not post the message to the UI thread), default false
addHeader(name,value)	Add custom request header to the task. Attention: We have already handled ETag, and will add If-Match & Range value if it works
addHeader(line)	Add custom request header to the task. Attention: We have already handled ETag, and will add If-Match & Range value if it is exist
removeAllHeaders	Remove all custom request header bind with the {name}
setMinIntervalUpdateSpeed	The min interval millisecond for updating the download speed in the downloading process(Status equal to progress). Default 5 ms. If less than or equal to 0, will not calculate the download speed in process
setWifiRequired	Set whether the task only allows downloading on the wifi network type. Default false
asInQueueTask	Declare the task is a queue task, what will be assembled by a queue which makes up of the same listener task and there is a method InQueueTask#enqueue() to enqueue this task to the global queue to ready for being assembled by the queue. The operation of method InQueueTask#enqueue() is the same to the Deprecated method BaseDownloadTask#ready(), we wrap the ready() method in this way just want you to know clearly: Only if the task belongs to a queue, you need to invoke this method otherwise if this task is an isolated task but you invoke this method, it's wrong and you will receive an exception(More detail reason please move to the exception thrown in DownloadTask#start)
start	Start task
pause	Pause task
getId	Get download id (generate by Url & path)
getUrl	Get download Url
getCallbackProgressTimes	Get the maximal callback count of FileDownloadListener#progress during the entire process of downloading
getCallbackProgressMinInterval	Get the minimum time interval between each callback of FileDownloadListener#progress
getPath(void)	Get the absolute file path or the absolute directory.
isPathAsDirectory(void)	Whether the result of getPath() is a directory path or directory/filename path
getListener	Get current listener
getSoFarBytes	Get already downloaded bytes
getTotalBytes	Get file total bytes
getStatus	Get current status
isForceReDownload	Force re-download,do not care about whether already downloaded or not
getEx	Get throwable
isReusedOldFile	Is reused downloaded old file
getTag(void)	Get the task's tag
getTag(key)	Get the object stored in the task as a tag, or null if not set.
isContinue	Is resume by breakpoint
getEtag	Get current ETag on header
getAutoRetryTimes	Get the number of times to automatically retry
getRetryingTimes	Get the current number of retry
isSyncCallback	Whether sync invokes callbacks of FileDownloadListener directly on the download thread
getSpeed	Get the download speed for a task. If it is in processing, the speed would be real-time speed; If finished, the speed would be average speed. Unit: KB/s
isUsing	Whether this task object has already started and used in FileDownload Engine
isWifiRequired	Whether this task has been set only allows downloading on the wifi network type
