Hey! Thank you very much for sharing this great code! It helped me a lot!
But I have on problem! I have created a ruby on rails webapp where I want to upload my image. On the website I can upload a image without a problem but when I want to upload the image with Android, the image cannot be uploaded for one reasen (but I don't know which)! I make a post request on the server (it passes all the right paramaters en the uploaded_data from the photo) but it won't save my photo in the database or upload it on my website.. Do i have to do something special with the website so I can upload an image from android to my website (server)?
