[Android] Download are cancelled with no reason

[DelattreAdixon]

Fork reproducing the issue :
https://github.com/DelattreAdixon/Xamarin-CrossDownloadManager
Launch the DownloadExample.Droid project, and look at the ouput. Some files are marked as 'Cancelled' :

...
[Property changed] Status -> CANCELED
content://downloads/all_downloads/3535
[Property changed] Status -> CANCELED

[DownloadManager] Remove -> New items: 0 at -1 || Old items: 1 at -1
[Property changed] Status -> CANCELED

Looking at the Xamarin

Steps to reproduce

1. Add several files in the download queue (more than 30 files), and start them

2. Some files are not downloaded. When checking the status for each download, we see that some files have been cancelled (though not cancelled intentionally), with no explicit reason.

Expected behavior

All files in the download queue should be downloaded

Actual behavior

Some download are canceled
