Complementing Android with Mobile OSGi

OSGi complements, not competesthe Android programming model

Technical Value Add

Mobile Web Widgets• 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

Technical Concept:• Middleware components are deployed into OSGi• OSGi Services (incl. custom code) can be 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)

Pushes the limits of web widgetsas developers can break out ofthe browser sandbox!!

Remote Management

Supported Features:• Android & OSGi App Lifecycle Mgmt• App Push Deployment• App Uninstall, Update• App Start/Stop

• Remote Configuration• Remote Monitoring• Remote Lock & Wipe• Server Initiated Session Support• Postload of Agent possible

Supported Standards:• OMA-DM 1.2• OMA-DLOTA 1.0• OSGi 4.0 MOs• SCOMO• LAWMO

• OSGi adds remote Management capabilitiesto Android

• Comes with fully inte-grated OMA-DM Agent

• Eases enterprise usageof Android devices

• Value add for customercare & maintenance

2

OSGi Programming Model

• 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

3

OSGi Use Case Example

• 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

Apps&

APIs

Add & manage yourAPIs & Appsat any time

You control the platformValue Add not Google

Lets you & the community do more than just Apps!Opens the Platform for Innovation

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
