The application allows delivery ofgraphics, themes and ring tones, Java ME applications, native SymbianOS C++ applications, videos, music and content developed using Flashtechnology.344RELEASING YOUR APPLICATIONIndependent channels are usually the preferred route to market forapplication developers working alone or in small companies, becauseit is easier to place an application for sale with the channel than toforge a relationship with a network operator or content aggregator. Thechannel will take a percentage of each sale of the application, but thisis typically less than a network operator or aggregator, and the channelwill allow developers to set the price of the application themselves. Forexample, the Nokia Software Market takes 40 % of the sales price set bythe developer, with revenue paid every quarter.
For more informationabout working with the Nokia Software Market and Catalogs application,please see www.forum.nokia.com/main/software market/index.html orconsult the Nokia Sales Channels section on the main Forum Nokiadeveloper site at www.forum.nokia.com.6.2.3 Content AggregatorsContent aggregators are specialists at gathering content, such as mobileapplications, video, and ring tones. The content is acquired from supplierssuch as games publishers or independent channels, and distributed by theaggregators to sales channels. Content aggregators provide an easy wayfor businesses to source downloadable material without having to seek itout and build a relationship with each supplier.
An example of a contentaggregator is Jamba, which is one of the largest channels for mobile content and applications. Jamba also distributes content and applications viathe Nokia Catalogs client on Nokia devices, as described in the previoussection. Forum Nokia publishes a comprehensive list of mobile contentaggregators at www.forum.nokia.com/main/go to market/aggregators.html.6.2.4 Pre-Installed ApplicationsOne way to distribute your application to users while avoiding thecomplicated relationship between publishers, content aggregators andnetwork operators is to get the application built onto a phone handsetby the manufacturer (or provided on a CD ROM in the box that contains the handset).
Naturally, there are far fewer opportunities for built-inapplications than there are developers who wish to get their application pre-installed onto a phone! The market exposure of an embeddedapplication is an excellent opportunity; however, it is not without itsproblems.
Trying to ship an application on a handset that is not releasedmeans the developer is often working with pre-commercial firmware andhardware. Final versions of the hardware may become available just daysbefore the deadline for embedded software on the handset, resulting inuncomfortable ‘crunch’ periods.WHERE TO GO NEXT3456.2.5 Open SourceIf you are interested in setting up an open source project, a goodplace to start is the open source page on Symbian Developer Network atdeveloper.symbian.com/main/tools/opensrc. You will also find a thrivingopen source community at opensource.nokia.com and, of course, atwww.sourceforge.net.6.3 Where To Go NextA range of technical papers, which can be found at developer.symbian.com/oslibrary, are published weekly on Symbian Developer Network.The papers cover all aspects of Symbian OS C++ programming, as wellas programming in other languages and runtimes, and range from thebasic through to the most advanced levels.
The technical papers covertopics such as the best techniques for debugging and error handling,how to use Symbian’s C++ idioms, how to solve particular problems andintroductions to using the new technologies available on Symbian OS.You can also find the Symbian OS System Model, as shown inFigure 6.1, at www.developer.symbian.com/main/oslibrary/sys models.Figure 6.1 The System Model for Symbian OS v9.2346RELEASING YOUR APPLICATIONA collection of FAQs is provided at developer.symbian.com/main/learning/faq.The Symbian Developer Network also has a wiki site, where youcan post contributions to content of relevance and of use to Symbiandevelopers.
The wiki is found at developer.symbian.com/wiki and isregularly updated by both Symbian staff and external developers – forexample, to record errata lists for the Symbian Press books, publishpresentations given at public developer events, and post useful links todeveloper blogs and websites, information about tools, open sourceprojects and example code.
