Ubuntu One for Android
Launchpad Entry: TODO
Created: 2010-03-27
Contributors: mkarnicki
Packages affected: none
Comment
This Spec is being heavily edited, consecutive sections will be revealed when finished
Notation: Apd stands for Android powered device (phone or other mobile Internet-enabled device)

Summary
This documentation specifies features, that would appear in Ubuntu One for Android platform. It justifies needs for specific features and their inner workings. The aim of the project is to deliver Ubuntu One service to Android powered devices (in particular, smartphones). The application would enable Ubuntu users not only to browse files in the cloud from their phone, but also share experience on the spot using URLs to their published U1 resources, instantly upload camera pictures or download music. Eventually, the aim would be to implement full-featured syncdaemon for specific UDFs. Ubuntu One is currently being intensely extended with new features, let's take that cloud mobile.
Rationale
Computer users like flexibility and there are more ways to get to your files in the cloud than through PC/laptop/netbook. Smartphones are becoming increasingly popular and the missing link here for Ubuntu One project is a client app for Android (amongst other platforms like iPhone & Blackberry). Daily use of mobile phones/devices justifies the need for such application. We can see recent proposals supporting this idea:
Use cases
When Victoria makes a picture using her Android powered phone, she can easily publish it by going to Menu -> Share -> Ubuntu One. She then can e-mail or tweet (or use otherwise) the public URL of that file easily.
Tom made some notes on his laptop last night, but forgot to take it with him the next day. No worries, he can open up Android U1 and browse the cloud for the file he needs.
Future: Each time Abby makes a picture with her phone, it appears on her computer (naturally, on whatever connection he prefers, wifi preferably, slower connections might not be suitable). She often forgets to take the USB cable with her, so she also prefers to manage music on her phone through the cloud (file sync).
Assumptions
Application developed in tight communication with Ubuntu One team to ensure flawless functionality and back-end support of proposed features.
Design
The application should be user friendly, have a clear interface and therefore be easy to use. This specification section will surely get expanded.
Features:
- browsing of cloud files
- downloading / opening of a cloud file
- uploading of a file (like a camera image) to cloud storage
- publishing a file to a public URL / publishing a file to a public URL and then sharing that URL with an Intent
- sharing a cloud folder with another Ubuntu One user
- implementing syncdaemon for specific UDFs
Implementation
The project will be developed in Java language, the choice of Android platform. CouchDB has an existing Android library, see links below.

BoF agenda and discussion
List of features that are possible (not necessarily feasible during summer period) for the project to implement. EDIT: We have picked the best/feasible ones for GSoC, features listed in Design section.
Planned/future features:
- File sync
full sync - for spacious SD cards and cheap data plan
semi sync - syncs only selected (favourite) files
sync on demand - TODO (manual/forced sync in some cases might be useful)
sync specific User Defined Folders
- Particularly: (all via Ubuntu One; no cables, much comfort; wifi preferred)
- Upload Music to Apd
Download Pictures from Apd
- That is - sync selected system-folders, also.
Let the user choose where to place the sync folder (default: Ubuntu One on SD card, if present) 5
Good file manager 6 (use Astro?)
- How sync works is dependent on the settings
- Which connection we want to sync on?
- WIFI/3G+ (HSDPA)
- 3G (EDGE, UMTS)
- 2G
- GPRS (ultra light sync, couchdb data perhaps)
- How frequently we want to sync? (battery drain)
- Should the files removed from U1 be removed from Apd? (This one is good. On the PC, you move Pictures to your home folder, and so they can be removed from Apd and free up some space. By default, file removal is disabled.)
- Which connection we want to sync on?
- Easy sharing
so called intent to share file by selecting option from Menu -> Share with -> Ubuntu One
- file is uploaded to the cloud (not sure how this would work; how would you have found a file on your Android device? there aren't file managers) (publishing a camera image, though, for example, would be great)
- user receives public link...(saving a file into Ubuntu One and then getting a public link for it is called "publishing")
- ..and can email it, tweet it, sms' it, share with barcode, etc -- make it easy to tweet the link by "sharing" the link with installed Intents
- Share a file to another specific Ubuntu One user
- Viewing files using intents (let other apps handle pdf or jpeg viewing, play an mp3, etc)
Special mode that allows backup/restore of the entire device 6
- Streaming data - would it be possible to watch a movie from U1 without downloading the whole file? (It might be a silly idea, but I wrote it down anyway.)
- Support for partial file updates [on the other hand - synced files with mobile phones are rather small..]
- the back-end software would have to support partial updates, nevertheless it is rather a case for U1 for PCs than Android powered phones. Users rarely edit graphis, for example. And editing text.. well, text files are small. You can always download/reupload a full file. All in all, this feature is interesting from algorithmic point of view and can be implemented as project continues after GSoC.
- showing notes
- editing notes
- showing contacts (contacts stuff needs to be thought about in conjunction with the Android client for mobile sync; that client is open source, so perhaps adding lots to it?)
- purchasing music from the Ubuntu One Music Store
- syncing playlists from Rhythmbox
Another idea (not necessarily feasible during summer /GSoc). We could design a plugin system to Ubuntu One (based on Android intents), similarly to what Locale application has. Then, any application that supports couchdb could plug in to Ubuntu One for Android to pull/update couchdb data in easy, uniform way (to say more concisely: open Ubuntu One for Android and:
- you have access to Tomboy notes if you have Tomboy plugin
you have access to passwords if you have Keyring plugin 7
you have access to any other couchdb per-application specific data, if you have specific-plugin!
https://launchpad.net/tomdroid - progress is little, we could integrate that functionality as a plugin
Comments and feature requests
Please leave any comments here. Feature requests and ideas are more than welcome!
I love this idea, one major request is playlist syncing from banshee as well as rhythmbox. Also, being able to backup my text messages to the cloud would be awesome.
Questions
If you have any questions about the project, leave them here or contact me directly (https://wiki.ubuntu.com/GSoC/2010/MichalKarnicki)
- Can I use Ubuntu One name openly? This project will be Open Source, I hope 'Ubuntu One' is not a trademark - if it is, who can provide formal agreement for such course.
Other/TODOs
How to add this page to https://wiki.ubuntu.com/CategorySpec ?
- Can I add my mentor to Contributors in the first section?
