OSGi on Android - Value Proposition

Complementing Android with Mobile OSGi

OSGi complements, not competes
the Android programming model

Technical
Value Add

Mobile Web Widgets
1
OSGi adds support for Web Widgets like JIL, Bondi, W3C, Opera, etc.
Support for multiple browsers and Flash
JavaScript APIs (custom APIs or enabler APIs) pluggable at any time
Best of Breed:
Browser for UI
Java for Business Logic

Mobile Web Widgets, cont.
1
Pushes the limits of web widgetsas developers can break out ofthe browser sandbox!!

Technical Concept:
Middleware components are deployed into OSGi
OSGi Services (incl. custom code) canbe auto-translated into Web Services
JavaScript APIs (i.e. wrappers for OSGi services) loadable from localhost
OSGi is fully manageable from remote (app lifecycle, diagnostics,etc)

Remote Monitoring
Remote Lock & Wipe
Server Initiated Session Support
Postloadof Agent possible
Supported Standards:
OMA-DM 1.2
OMA-DLOTA 1.0
OSGi 4.0 MOs
SCOMO
LAWMO

OSGi Programming Model
3
Full support for all OSGi features
OSGi Sevices can be consumed by Android apps
Event bus integration between OSGi and Android
OSGi has become a mainstream Javaprogramming model with a growing community
OSGi brings a huge pool of existing componentsand knowhow to the Android space
OSGi turns Android into a true enterprise SOA

OSGi Use Case Example
3
OSGi simplifies implementing (Digital Life Network Alliance)
Hides complex DLNA protocol behind API
Offer APIs to developers to create apps on top

OSGi Value
Propositions

Proposition for Carriers and OEMs
Lets you & the community do more than just Apps!
Opens the Platform for Innovation
Add & manage yourAPIs & Apps
at any time
You control the platformValue Add not Google
Apps
&
APIs

Proposition for Corporate Enterprises
Enterprises discover mobile handset as strategic elements of their IT infrastructure. However, Android does not come with all required features:
OSGi provides enterprises an own remote management channel right into their applications
OSGi adds application push deployment and lifecycle management.
OSGi offers Lock& Wipe, a key requirement

Proposition for Developers
Web and J2EE developers become mobile developers without additional learning(due to Widget and OSGi programming models)
Developers can turn Widgets into powerful localapplications with full access to all phone features
Developers have control over the APIs on the device (they can add their own API at any time)
Developers can reuse their existing OSGi Java assets
Developers can modularize their applications

What is OSGi?

OSGi: An Open Industry Standard
The Dynamic Module System for JavaTM
Specification developed by the OSGi Alliance
Adopted by a rapidely growing community

OSGi: Architecture
OSGi is a manageable component framework
It hosts apps, services and middleware
It can inject functionality into the browser
