Storing data online ANDROID
Not sure if this is exactly what you are looking fore, but dropbox provides a great android api: http://www.dropbox.com You can upload/download/modify files pretty easily. However, this would not be the best solution onless you want to give user's the ability to sign into their own dropbox and save/modify files on a per-user basis. It seems like you might be looking for something more like Amazon s3 storage: http://aws.amazon.com/s3/ . It is a very popular cloud storage provider, and you get 5 gigs free (I think), plus it should be simple to integrate with android. see here amazon S3 and android and here: http://aws.amazon.com/pt/sdkforandroid/
