    \section1 Overview

    \section2 Introducing the QtMobility Project APIs

    The QtMobility project covers a diverse range of features and technologies.
    It is not a single API but a collection of APIs and frameworks.

    This release contains the following APIs:

    \annotatedlist  mobility

    These APIs give the developer a range of desirable functions for a
    mobile platform, but now these functions become possible on platforms not
    traditionally associated with some of the features. A mobile device
    using the QtMobility Project API would be able to
        \list
        \o Locate services on-board or remotely. Find an optimal
    connection to the network for the particular service.
        \o Services built on top of these APIs would include Internet
        applications such as email and web browsing.
        \o Multimedia features enable image and video capture with audio ,
    audio recording, and the playing of music or video clips.
        \o Location will make the device aware of its geographical location
    to support GIS applications.
        \o Publish-Subscribe enables communication between separate objects
        whether local or remote to the device.
        \endlist

    The New Qt APIs deliver to developers an enabling package. It
    will be used by developers to build a variety of applications and
    services that are mobile capable or familiar to mobile users,
    irrespective of whether the platform is mobile or not. This means that
    there is the possibility of easy transfer of user experience from PC to
    phone or vice versa.

    \section1 Getting Started
    To get started with QtMobility see the
    \list
        \o \l {Installation Guide}
        \o \l {Quickstart guide}{Quickstart Guide}
        \o \l {QtMobility Examples}{List of all examples.}
    \endlist

    For users on the supported Symbian platforms, shown at the bottom of this
    page, see the instructions at the
    \l{http://library.forum.nokia.com/topic/Qt_for_Symbian_Developers_Library/GUID-7E53D0F7-72CB-41C4-8807-FE7A772B0DB4.html}{Qt For Symbian Developer's Library}

    \section2 Known Issues
    See \l {Release Notes of the QtMobility Project release}{Release Notes}.

    For an overview of Platform Compatibility see \l {Platform Compatibility}.

    \section1 The QtMobility APIs

    \section2 Service Framework

    A platform independent method of finding Services. A 'service' is an
    independent component that allows a client to perform a well-defined
    operation.

    The services are implemented as plugins installed on the device and can
    look for supporting external services running on a central server. E.g.
    weather, local tourist attractions etc. Default applications can use
    the layer to locate servers.

    Since this is an abstraction layer then the app does not need to be
    concerned with the underlying protocol, where the servers are, the
    hardware peculiarities with networking and other low level details.

    For more details see the \l {Qt Service Framework} {Service Framework API overview}.

    \section2 Messaging

    A common interface for handling SMS, MMS, MIME Email and TNEF Email
    messages. Enables access to messaging services to search and sort
    messages, notify of changes to messages stored, send messages
    with or without attachments, retrieve message data, and launch the
    preferred messaging client to either display an existing message,
    or compose a message.

    For more details see the \l {Messaging} {Messaging API overview}.

    \section2 Bearer Management

    Although not a network manager, this component manages the connectivity
    state of the device to the network. So it does not manage network
    configurations, which are the role of the platform provider, but it does
    allow the user to start or stop network interfaces. Some higher level
    management of the connection session may also be possible as well
    depending on the platform.

    Some platforms can have a set of grouped access points perhaps based on a
    common purpose. Bearer Management allows comparison and prioritization
    of the access and use of these points.

    The aim of Bearer Management is to reduce the need for the developer to be
    concerned about trying to locate the best connection from a list of
    possible IP bearers and 3G connections. The user can select the best or
    it can be selected transparently so that WLAN roaming can occur
    seemlessly.

    Some examples of the Bearer Management functionality,
        \list
        \o On demand use of the appropriate Access Point. When a user starts
    to use a browser, the appropriate access point is selected from those
    available and a connection is transparently made.
        \o Always-on applications such as email or IM roam automatically
    between cellular packet data and WLAN networks. The application developer
    is in control and for example the application can gracefully close TCP
    connections over the old bearer after setting up new TCP connections
    over the new bearer.
        \o Application developer can create a settings user interface, where
    the user can select a certain connection to be used with the application
        \o A connection manager application can be implemented with Qt. This
    application enumerates available connections, shows counters, and allows
    the user to connect or disconnect
        \endlist

    For more details, see the \l {Bearer management} {Bearer Management API overview}.

    \section2 Publish and Subscribe

    Will enable context sensitive access to information in future releases.
    Data is organized as a tree, with data being able to 'shadow' other
    data with the 'same key', a string specifying the leaf or node. The
    context is an example of a context ontology, a defined set of
    relationships. As the context changes the values of the objects change
    but the relationships remain the same. It is intended to be an enabling
    technology, the basis of a range future applications.

    At this stage the API is intended to act as a common communications
    method between applications, whether local or remote.

    For more details, see the \l {Publish and Subscribe} {Publish and Subscribe API overview}.

    \section2 Contacts

    The structure and retrieval of contact data from local or remote backends.
    It includes the ability to create, edit, list, delete and lookup contact
    information whether it is stored locally or remotely.

    For more details, see the \l {Contacts} {Contacts API overview}.

    \section2 Location

    The location API is composed of 3 components. Location positioning,
    landmarks, and mapping and navigation.  The location positioning API provides an easy to
    use interface that encapsulates basic geographical information obtained
    from satellite or other sources about the user, including latitude and
    longitude, bearing, speed and altitude.  The Landmarks API allows storage and
    retrieval of points of interests while the Maps and Navigation API provides
    mapping, geocoding and routing functionality.

    For more details, see the \l {Location API} {Location API overview}.

    \section2 Multimedia

    An API to play audio and video of various formats. Record audio. The playing
    and managing of an FM radio. This includes the typical functionality you
    would find on a music and video player, combined with an FM radio.

    For more details see the \l {Multimedia} {Multimedia API overview}.

    \section2 System Information

    An API to discover system related information and capabilities. Information
    available will cover software version numbers, hardware features,
    network connection types and status, display, data storage devices,
    device information and the screensaver.

    For more details see the \l {System Information} {System Information API overview}.

    \section2 Sensors

    An API for accessing hardware sensors. This covers both high-level
    sensors such as screen orientation (portrait, landscape) and low-level,
    real-time sensors such as accelerometer data.

    For more details see the \l{Sensors}{Sensors API overview}.

    \section2 Versit (vCard)

    An API to manage Versit \reg documents, such as vCards.

    For more details see the \l{Versit}{Versit API overview}.

    \section2 Organizer

    An API for management of calendar, scheduling and personal data
    from local or remote backends.   It includes the ability to create,
    edit, list, delete and lookup organizer information whether it is stored
    locally or remotely.

    For more details, see the \l {Organizer} {Organizer API overview}.

    \section2 Versit (Organizer)

    This is a continuation of the Versit API to interface the Organizer API
    with iCalendar documents using the same framework as for vCards.

    \section2 Camera

    The Camera API provides control of system camera devices. Providing
    support for still or video image capture with sound support. This functionality
    is part of the Multimedia API.

    For more details, see the \l {Multimedia} {Multimedia API overview}.

    \section2 Landmarks

    The Landmarks portion of the Location API facilitates the creation,
    retrieval, updating and deletion of landmarks from arbitrary data stores.

    For more details, see the \l {Landmarks} {Landmarks API overview}.

    \section2 Document Gallery

    An API for accessing collections of documents and media and their meta-data.

    The Document Gallery provides an interface to a searchable index of
    document meta-data.  The gallery may be queried to discover the meta-data
    of documents, or to discover documents with desired meta-data.

    For more details, see the \l {Document Gallery}{Document Gallery overview}.

    \section2 Feedback

    The Feedback API enables a client to control the vibration of the device
    or the piezo feedback from the screen.

    For more details, see the \l {Feedback}{Feedback API Overview}.

    \section1 The QtMobility Namespace

    The QtMobility APIs are placed into the QtMobility namespace. This is
    done to facilitate the future migration of QtMobility APIs into Qt. See
    the \l {Quickstart guide} for an example on how
    the namespace impacts on application development.
