It's very very dificult to develop an Mobile APP for Nokia with QtMobility! Any one help me pls!

hungchuviet

Thank you!
I'm a beginer QT, I'm a C#,MS C++, SQL server, Oracle develper for a long time
I've spend 6 days to install and configure Nokia QT SDT, QTMobility.
I have 2 computer,I've installed Nokia QT SDK, QtMobility, Active perl, CarbIDE.c++
on all of them:
On my mobile phone I've installed:
1.QT for symbian
2.QTMobility for symbian
3.TRK
4.SQLIte

My project work on 1 computer, on other Computer my app not work. if i desable QtMobility, my app work fine. (The app have

some line of codes)

Alot of error happend:
1.Requested application not granted
2. No such file or directory ....
3. OS-Related Error
4. Include..... not found

I think, Nokia may be release install package for different platform (Ex: Windows, Unix, Linux )
each palatform need only one install package (All in one) and simple guid to install.
The same project, the same computer, some time it work, another time it not work, I don't know
what's happend.
Here is my code:
@
//-----------------
untitled.pro

QT += core gui
TARGET = untitled
TEMPLATE = app
SOURCES += main.cpp
mainwindow.cpp
smslib.cpp
HEADERS += mainwindow.h

CONFIG += mobility
MOBILITY = systeminfo messaging
symbian {
TARGET.UID3 = 0xeac1efb9
TARGET.CAPABILITY=NetworkServices
LocalServices
ReadUserData
WriteUserData
UserEnvironment
ReadDeviceData
WriteDeviceData
TARGET.EPOCSTACKSIZE = 0x14000
TARGET.EPOCHEAPSIZE = 0x020000 0x800000
}

// Match all messages whose status field includes the Incoming flag
QMessageFilter filter(QMessageFilter::byStandardFolder(QMessage::InboxFolder));
//QMessageFilter filter(QMessageFilter::byStatus(QMessage::Incoming));
// Order the matching results by their reception timestamp, in descending order
QMessageSortOrder sortOrder(QMessageSortOrder::byReceptionTimeStamp(Qt::DescendingOrder));
// Acquire a handle to the message manager
QMessageManager manager;

// Find the matching message IDs, limiting our results to a managable number
const int max = 100;
const QMessageIdList matchingIds(manager.queryMessages(filter, sortOrder, max));
// Retrieve each message
foreach (const QMessageId &id, matchingIds) {
    QMessage message(manager.message(id));
    retVal.append(message.content());
}
return retVal;//

Have you seen "this posting":http://labs.qt.nokia.com/2010/10/04/important-update-on-qt-mobility-1-1-0-beta-package/? Maybe that solves it?

Thank you!
Yes. I follow this guid "Important Update on Qt Mobility 1.1.0 Beta Package" to fix bug. but my app doesn't work.
I'm very tired

Hello,

Let's look at how you've handled signing. All mobile phone platforms require apps to be signed. Symbian breaks capabilities into a few categories (click "here ":http://developer.symbian.org/wiki/index.php/Capabilities_(Symbian_Signed) for more detail ). Most of the capabilities you reference are user grantable. ReadDeviceData and WriteDeviceData are not. They are system capabilities which require a different kind of signing ( click "here ":http://developer.symbian.org/wiki/index.php/Category:Symbian_Signed for more detail ).
