After DownloadManager has downloaded an application to cache to install during low memory condition, we try to free cache to fit the new application. The free cache function deletes older files first, but it will also delete the downloaded application (since it's in cache) as a last resort since installd has no context about it. This just changes the error code returned in this case so that we'll give something more meaningful to the user. A later fix should actually make this more sane. For instance: know which file to avoid deleting, not even trying to delete anything if it won't arrive at the desired free space. Bug: 7684538 Change-Id: Ide77320fc51a4f692ef8042cb0eafe17b5cd279d
