Host and Target Platforms

• Host System OS Fedora 12, 13, 14 Ubuntu 10.04, 10.10 Windows XP SP3, Windows 7 TBD: Mac / OS X

• Target Platforms x86 Netbook, x86 Handheld (nCDK or Avaa?), n900

Includes images for the device and emulation in QEMU

6

Installation

• Single SDK file download• GUI-based (Qt) Installer for all hosts• Current status:

• Windows: meego-sdk-installer.exe• Linux:

1. Update system repo config2. Install meta-package3. Download vertical build tools and QEMU image(s)4. Configure Qt Creator to use correct tools

7

Emulation

• Qt Simulator−*New with Qt Creator 2.1. Preview available by mid-February

−Ability to run/debug Qt and QML applications

−Device simulation

• QEMU Virtual Machine−Boot full MeeGo OS on host

−Integrated with Qt Creator. Button to launch QEMU for running/debugging

−Coming: Accelerated graphics (Linux only)

• Flexible skin framework−Defaults for handset and tablet. Customizable: add skin for your device

−Map skin areas to events (click button sends event to QEMU)

−Rotation

−Zoom in/out skin and QEMU

Virtualized Devices / Sensors• Keyboard / Kpad / DPad / Trackball / Platform buttons• Mouse • Touchscreen• Landscape mode and Portrait mode support• Screen Rotation

• Audio• Network• Battery• Camera• GPS • Telephony

• Incoming calls• Incoming SMS• Incoming email

• CF/SD/MSP/XD, plug-in/pull-out• USB connection/eject• AC Battery Charge (Get Level and State)• Flexible Resolutions (864*480 for Aava..)• Accelerometer• Magnetometer• Ambient light• Nand Flash• Card-in-one Support (CF/SD/MSP/xd…)• Bluetooth• Video Capture

Currently available

Planned to be implemented

Tools

• Packaging−“Package and deploy” for debugging (Simulator, QEMU, or device)

−Package for deploy to a store

−Integrated into Qt Creator

−Documentation guidance

−Example applications

• Compliance• Application and OS checkers. Documentation.

• Integrated into Qt Creator (future)

• Performance−Performance measurements: CPU and memory usage

−Integrated into Qt Creator (future)

MeeGo API

11

MeeGo API

• Platform API: APIs for all components in the MeeGo core. Documentation derived from respective projects. No compatibility guarantee. Not productized. Subject to change.

• Extension API: Set of productized interfaces for MeeGo platform. Compatibility e.g. within Minor release, individual API can be marked as deprecated (will be removed in the next major release)

• MeeGo API: Stable, productized, forward compatible set of interfaces. Source code compatibility within Major MeeGo release (the same as Qt).

12

MeeGo 1.2 API Proposal (not final)

MeeGo API • EGL 1.4

− Required for Open GL ES • OpenGL ES 1.1

− For fixed function hardware, emphasizes image quality, graphics acceleration, and high performance.

• OpenGL ES 2.0 − Enables full programmable 3D

graphics.• Qt 4.7

− The core Qt Framework• Qt Mobility 1.2

− Backwards compatible with 1.0 version

• Qt WebKit 2.2− Delivery separated from Qt

Framework• Qt Components 1.0 *

− First set of common Qt Component API

* Requires further definition

Extensions• Accounts-Qt

• To be replaced by QtM Accounts API from 1.3 onwards• Signon

• To be replaced by QtM Accounts API from 1.3 onwards• Telepathy-Qt4

• To be replaced by QtM Presence, IM & Telephony API from 1.3 onwards• QmSystem

• To be gradually replaced by QtM System Info API• QtSparql

• To be pushed to Qt Fw 4.8• Resource Policy

• To be replaced by QtM API from 1.4 onwards• EGLIBC

• Every UNIX operating system needs a standard C library that facilitates the usual system and library calls and provides core services, since these are not integrated to the C language.

• GLib • GLib is a general-purpose utility library, which provides many useful data types,

macros, type conversions, string utilities, file utilities, a main loop abstraction, and so on.

• GStreamer • GStreamer is a development framework for creating applications like media

players, video editors, streaming media broadcasters and so on.• PulseAudio

• PulseAudio provides features like Per-application volume controls, extensible plugin architecture with support for loadable modules, low-latency operation
