I've built an app to upload images to imageshack.us, and it doesn't have any ads (yet ).
When I try to upload images that directly taken from whatsapp, it fails with IOException.
After I switched ROM, disable xposed... I found out that when I disabled AdBlock Plus it work perfectly.
here is the logcat - http://pastebin.com/VgMQZ5RS
