I have a web page where I can download a contact file (.vcf / vcard) to my Android phone and then open it to add to contacts.
The file is very small, only around 260-270 bytes.
On different versions of Android and different phones, the success rate of the download varies greatly.
On my Samsung Nexus S (ICS 4.0.4) using the stock browser and download manager, the download fails about 4 out of every 5 times.
If I look at DDMS locCat output I see
06-20 16:25:56.701: W/DownloadManager(6942): Aborting request for download 6728: Trying to resume a download that can't be resumed
On another Samsung Nexus S (ICS 4.0.4) it fails one out of 5 times.
When I download larger files, or apps, etc I don't see this problem.
Anyone have any idea why this download may fail so often? Could it be related to the fact the file is so small?
