All task data will be stored in FileDownlaoder Database, and FileDownloader will maintain it automatically.

You can get bellow data anywhere with a DownloadId.

// Get the status. FileDownloader.getImpl().getStatus(downloadId); // Get the downloaded so far bytes. FileDownloader.getImpl().getSofar(downloadId); // Get the total bytes. FileDownloader.getImpl().getTotal(downloadId); 

And you can get some other data from the call-back method in FileDownloadListener:

Ref: BaseDownloadTask

For example:

task.getTag(); task.getTag(key); task.getEtag(); task.isReusedOldFile(); task.isResuming(); task.getUrl(); task.getEx(); 

P.S: If you need some more data, recommend maintain your own Database for your business, Ref: TasksManagerDemoActivity
