HI Isaiah, I manage to get the solution work in phonegap. But in order to get it work with older webkit such as Jelly bean & before, I have to switched to blobbuilder instead of blob construct. And replacing blobbuilder to blob, I keep getting "internal server error" log from my arcgis server manager when attempting to addattahcment. I checked the files in arcgisuploads > scratch folder and fould out that the file size is 0KB, with name of {fileid}.uploads. Anyone got any ideas on this? Does this mean the files is corrupted ? I can still see/view the files that are uploaded successfully with blob construct. thanks,
