Post android file to drupal site

I have an android mobile application ([login to view URL]) which is supported by a Drupal website ([login to view URL]). I'm already using Drupal services to download and rate clocks (drupal custom nodes). I want to add the ability to upload clock files directly from the application, so I need a module to integrate into the app that uses [login to view URL] and [login to view URL] to create a clock node with a file and an image as an attach. Project tasks: - Extend DrupalCloud to include [login to view URL] - Provide async method/class to: . login into Drupal . upload image file (previously created) . upload clock file (previously created) . create node attaching the two files JSON should be used! - Screen implementing the upload asking for the node title and description I can provide full support to the development!
