Product

Music Store is an offline music shop for mobile phones. Music Store is a unique application, as it differs from many analogues. Its unique feature is the ability to provide previews for music tracks which could be bought by a user in a safe mode. The application downloads up-to-date catalogs of tracks from the service-provider server, and a user can listen to track preview before buying it as a ring-tone or a full track. The pre-listening is organized in a safe way: the application downloads the tracks to the secure Java storage from which they are not reachable for other purposes but for the use by the application. As a JAVA application, Music Store provides user-friendly look-and-feel with highly customized design and convenient controls. Such features would be lacked on WAP page.

Music Store also provides user commercial information which it receives from server in different ways, e.g. colorful promo banners, server alerts and browser links. Thus, being an application which is eligible for offline launch (user can browse the once loaded catalogs offline), Music Store can maintain frequent connections via HTTP with server-side service engine, which controls the client's behavior in many ways.
