1. Overview and demo of Nokia Qt SDK 1.0

2. Taking your Qt app to Nokia platforms usingNokia Qt SDK The topics that you need to know about

Symbian and Maemo and how to handlethose.

3. Publishing to Ovi and Ovi Store SymbianSigning Service

4. Spicing up the soup with platform SDKs When you might want to tap into

platform specific SDKs focusing onSymbian.

Soup of today

Switching Target Platforms

Select Symbian or Maemo target

Build, deploy and debug

Supports also switching the target

to Remote Compiler or

Symbian Emulator


9/65

Remote compiler

For Mac and Linux local builds for Symbian are not

supported

Builds can be done remotely using remote compiler When installing Nokia Qt SDK select remote compiler from the

Experimental section

Your application sources are sent to a Nokia server where the

build is done

You get back a ready installer package (sis for symbian, deb for

maemo)

Taking your Qt application to

Nokia platforms

The topics to consider


12/65

Taking your app to Nokia

platforms the laundry list

Symbian - minimum laundry list

1. Optimize the app

2. Get an UID

3. Figure out the capabilities

4. Do an icon

5. Modify .pro file

6. Test on several devices

7. Create a sis file with Nokia Qt

SDK8. Sign the sis file

9. Take smart installer into use

10. Distribute the embedded pkg

Maemo - minimum laundry list

1. Optimize the app

2. Do an icon

3. Modify .pro file

4. Test on the Nokia N900

5. Tweak the debian files for

Nokia Qt SDK6. Create the debian package

7. Distribute


13/65

Optimization

Know the limitations of the target devices.

To provide the best experience optimize

UI

Resource usage: Memory, network usage, speed

UI optimization, atleast:

MainWindow w;

w.showFullScreen(); //w.showMaximized();

Network usage : avoid significant data transfer, atleastif not in WLAN

Consider the usage of Qt Webkit in your application.


14/65

Application features

When taking your applicationfrom desktop to smartphones

dont stop when you get it

working. Think about how you

can improve the user experience

with mobile specific features.

Qt + Mobility offers already a

pretty comprehensive set offeatures.

You might still want to spice up your

application with some platform

specific use cases like home screen.

Symbian platform security -

background

1. Capability model APIs protected with capabilities

Indicates application signing

2. Process identity

Each process has a unique identifier (UID)3. Data caging

Apps cant access all data on the device

Figuring out the capabilities

Majority of Qt applications will manage withthe user and system capabilities.

With few known exceptions, f.ex Bearer Mgmt APIs

certain use cases require NetworkControl

How do I figure out the capabilities?

Documentation

Try, Error, Fix

Use Symbian platform tooling demo later on


19/65

Icon

Use SVG-T See examples, f.ex

C:\NokiaQtSDK\Examples\4.6\animation\animatedtiles\

animatedtiles.pro includes symbianpkgrules.pri file

which defines the following

vendorinfo= \

"; Localised Vendor name" \

"%{\"Nokia, Qt\"}" \

" " \

"; Unique Vendor name" \

":\"Nokia, Qt\"" \

" "

examples_deployment.pkg_prerules += vendorinfo

DEPLOYMENT += examples_deployment

isEmpty(ICON):ICON = $$PWD/qt.svg


20/652

Symbian platform security how to in Qt

Everything you need in a Symbian OS MMP file, can be defined in the Qt

.pro file Symbian-specific extensions should be defined inside a special block as

shown below

TARGET = HelloWorld // Not Symbian-specific

TEMPLATE = app // Not Symbian-specific

symbian {

// LIBS-keyword as such is not Symbian-specific, but bitgdi library is

LIBS += -lbitgdi

ICON = ./images/myIcon.svg

TARGET.UID2 = 0x100039CE

TARGET.UID3 = 0xA000017F

TARGET.SID = 0xA000017F

TARGET.VID = 0x70000001

TARGET.CAPABILITY = NetworkServices Location

// Qt app stack typically larger than 8kb

TARGET.EPOCSTACKSIZE = 0x5000

// Min 128Kb, Max 16MbTARGET.EPOCHEAPSIZE = 0x20000 0x1000000

}

This way the same .pro file would potentially work in otherenvironments as well


21/65

Platform security & signing summary

Symbian native apps need to be signed. Neededsigning process depends on applications capabilities

In case Restricted or Manufacturer capabilities are needed

signing needs to happen in Symbian Signed, where a publisher

ID is needed (and you need to have a company to get one)

CommDD ,DiskAdmin, NetworkControl, MultimediaDD & AllFiles, TCB, DRM

You should very rarely run into this situation.

Individuals can publish to Ovi store and get their

application signed in Ovi Store Symbian Signing

Service free of charge

24/65

Publishing Qt apps for maemo

First create the debian package and test it withNokia Qt SDKs maemo tools (MAD) on N900

The debian package created by Nokia Qt SDK isa development version.

To make one for publishing a bit of tweaking is

needed. For details seehttp://wiki.maemo.org/Packaging_a_Qt_application

Smart installer overview

Scenario is

Sign your application

Create a embedded package that contains

Your application

Smart installer Publish the embedded package

Qt for Symbian SDKs qmake supports automatic creation of the

package.

Smart installer and Qt versions

Note; The newest Qt versions may not be available for applicationdistribution i.e exist in Smart Installer server.

Once you build an app with Qt the dependency is automagically set to

that version (f.ex 4.7.0). If that version is not available for the target device smart installer will fail

Using what is available in Nokia Qt SDK i.e Qt 4.6.3 is the current

commercial solution

For checking what is available for distribution :

http://tinyurl.com/SmartInstaller

If youre using mobility or Qt Webkit the dependencies will be created

automagically by qmake and those components will be installed

along with your application

Smart installer sis file is in NokiaQtSDK\ Symbian\SDK

Steps to take smart installer

into usage

Build the app qmake app.pro

make release-gcce

Now depending on the signing process you select

1. Ovi Store Symbian Signing Service : use the certificatesyouve gotten from them to sign the application and the

embedded package. Test.

2. Symbian signing : sign the application with your published

ID. Send the application for signing. Once you have the signed

application back create the embedded package. Lets go through the creation of package for

Ovi publishing (using Ovi Store Symbian

Signing Service) next

C ti th k f O i

Creating the package for Ovi

publishing

Planning to publish collindingmice (which Idefinitely own and have rights to publish ;)

qmake collidingmice.pro

32/65

To support Symbian^3

After youve run qmake patch the .pkg files(_template.pkg and _installer.pkg)

Locate the following lines

; Default HW/platform dependencies

[0x101F7961],0,0,0,{"S60ProductID"}[0x102032BE],0,0,0,{"S60ProductID"}

[0x102752AE],0,0,0,{"S60ProductID"}

[0x1028315F],0,0,0,{"S60ProductID"}

Add Symbian^3 product ID to the list and save the file

Change the UID to 0x2002CCCF (smart installer

UID)

#{"collidingmice installer"},(0x2002CCCF),1,0,0

Set the vendor name to both packages; Localised Vendor name

%{"Vendor"}

Qt apps on Ovi store

Currently : Qt apps can be published for Symbian and Maemo devices using Qt

4.6.3

Currently 19 devices supported (29th of October 2010): Symbian^3: N8-00, C7-00, C6-01, E7-00

due to recent issue no new content should be published until Store 2.2 (coming in some

weeeks)

S60 5th Edition devices: X6-00, N97 mini, C6-00, 5800, 5530, 5230, 5228, 5235, N97

S60 3rd Edition devices: E72, E71, E63, E52, E66

Maemo/Meego: N900, with PR1.3 and Qt 4.7

Next ones targeting wk 44 are : 5250, N95 8GB, N95, E72, N82, 5233,

5232, Nuron C5-03

Early 2011 : Qt 4.7 based application distribution enabled*

* 4.7 apps can be deployed to N900 already once PR 1.3 is available


40/65

Publishing Qt apps to Ovi

Register as an Ovi publisher For individuals cost is 1 euro

For maemo no signing is needed, after testing one can

move on directly to publishing

For Symbian Ovi signing and publishing (which is also free) for individuals

Or symbian signed (in case of restricted/manufacturer

capabilities) for companies

Ovi Store Symbian Signing Service

Registering :

1. Emails publisher support ([email protected]) to start the registration process.

After accepting and signing the terms and conditions

2. Publisher provides IMEI numbers for up to 5 devices for testing purposes

3. Ovi Publish support sends publisher UIDs, a cert installer, and developer cert/key pair for

testing their app

Publishing:

1. Ovi Publisher packages the SIS file using the UID provided and tests on their device making sure

is tested against Symbian Signed test criteria

2. Ovi Publisher submits their app to the intake tool

3. QA will test the app based on Nokia content and store guideline, specific operator guideline and

Symbian Signed test criteria. If it passes, it will be express signed by Nokia and published intoOvi Store
