android java.io.eof error when uploading image to server
Question
I have been playing with this code for quite a few hours now and I can't seem to resolve the end of file error.
The gist is that you can select a file from the gallery or take one using the camera and then it uploads to a server.
I keep hitting the exception just after checking the http response code.
Can anyone shed any light on whats going on? I have been looking to long to see the obvious i think!
