Add Cloud Storage to an Android App

This project is to add cloud storage of PDF files to an existing Invoice Android app. Currently, when user creates an invoice, the PDF file representing the invoice is saved to local file storage, the goal of this project is to take the PDF file that was generated, send it to cloud storage and return a user friendly url (example: [login to view URL] ) back to the app. The returned url should be world readable. When user emails or sends the file via SMS, the returned URL is used to send the PDF file as an attachment. When the user receives the email, a push notification is sent to the device/app informing the user that the email has been received. If user clicks on the notification, user should be taken to an Activity. When user reads the email, a push notification is sent to the device/app informing the user that the email has been read. If user clicks on the notification, user should be taken to an Activity. The Activity name will be provided. More information about the project is provided in the attached PDF. Please read the PDF document before you place a bid.
