Filedownloader: get background task

[mohamadrezash]

I want to make an app like googleplay. how can I get downloading tasks in a separated activity?
thanx

Sorry, FileDownloader doesn't provide any method to get downloading tasks.

There are several reasons:

1. The data in filedownloader isn't bound any View/Activity.
2. The data cached in filedownloader is used for maintaining the work of downloading and message flowing. The data store in the internal filedownloader database is used for ensuring any tasks can resume from the breakpoint in any valid situation.
3. The data cached in filedownloader will be changed for more stable in many upper users don't know unexpected situations.

So, we don't commend the upper logic coupled with the filedownloader internal data.

Solution:

For upper layer, for more flexible and more stable, very recommend maintaining the downloading data by yourselves. Refs TaskManagerDemo.

I thank the wiki is helpful to you.

I'm writing the more readable java doc for this library and I'm perfecting the architecture of the visible layer(BaseDownloadTask、FileDownloadTask) for more readable too, you will find those until the next version(v1.0.0).
