Android Developers. I am working on an app and one of the features I am working on is to download some binary files. Some of them are really big more than several mega-bytes. Downloads are completing fine as long as the file size is less than 2 GB.

I got stuck on a file that is 3. Doing some extra investigation, I found out that this seems to be a bug in Android DownloadManager implementation. It seems Android implementation stores the download count as an int, but when that count goes above Integer.

I am thinking to replace the DownloadManager usage with a foreground service, but I wouldn't give up yet Did you guys face this and if so, how did you fix it? Is there any work-around to use DownloadManager in pre To download such a large files, you need to download those in chunks. Either you can use any library that support HTTP range options to allow to pull down a single file in multiple pieces , supporting resume etc. Or you can split your large file on your server then have a text file with MD5 hash of each file, when you first start to download then get the MD5 file once finish then check that hashes matches the downloaded pieces.

If they do not then delete that piece and add it to queue of items to download. There is a 4 GB per file limit with this file system. It seems that the only way to work around this on older platform versions would be to modify the server such that it uses chunked transfer encoding[1] for these large resources. In that case, that Download Manager will ignore and not attempt to parse the Content-Length header. You can not fix the DownloadManager.

If it's a bug in it, it will be so. Therefore, in short, No , you can not workaround this issue using the DownloadManager. You could however workaround it using a server side approach that has been put into words in the other answers. So, I think your simplest solution would be to force the minimum sdk level to JB-MR2 because ksasq mentioned that this issue has been resolved.

If that is not plausible nor in your case possible, you can find the best file download library out there and create an interface similar to DownloadManager's for this library. Everything works fine here from Android api Android implemented scoped storage and so deprecated the getExternalStoragePublicDirectory As a result I need to figure out a compatible solution to support APIs I cannot use internal application storage since DownloadManager will throw a SecurityException.

Androids documentation states that I can use the DownloadManager. When I do this though, the path is still the emulated path:. I get a callback from the download manager that the download is complete with right ID but then I cannot grab the download from the area I saved it to. I check to see if the file exists and it returns false:. You need to ask the user where to download the files too, this will get you a URI for the DownloadManager destination.
