I guess there are no fortune tellers nor mind readers in Qt Developer Network so it will be better to show your source code :)

hahahah right! =) why can you everytime understand me? =P

Add more folders to ship with the application, here

folder_01.source = qml/Werfer
folder_01.target = qml
DEPLOYMENTFOLDERS = folder_01

Additional import path used to resolve QML modules in Creator's code model

QML_IMPORT_PATH =

symbian:TARGET.UID3 = 0xEC4A8CB9

Smart Installer package's UID

This UID is from the protected range and therefore the package will

fail to install if self-signed. By default qmake uses the unprotected

range value if unprotected UID is defined for the application and

0x2002CCCF value if protected UID is given to the application

#symbian:DEPLOYMENT.installer_header = 0x2002CCCF

Allow network access on Symbian

symbian:TARGET.CAPABILITY += NetworkServices

If your application uses the Qt Mobility libraries, uncomment the following

lines and add the respective components to the MOBILITY variable.

CONFIG += mobility
MOBILITY += multimedia messaging contacts systeminfo

Speed up launching on MeeGo/Harmattan when using applauncherd daemon

CONFIG += qdeclarative-boostable

Add dependency to Symbian components

CONFIG += qt-components

i am using symbian^1!

leon.anavi

I suggest to add proper "Symbian capabilities":http://developer.qt.nokia.com/wiki/Symbian_Capabilities to the pro file. I think that QContactManager requires ReadUserData and ReadDeviceData but you might need something else too.

spode

may you help me? i am using: QContact, QMessage and QMediaPlayer for symbian...

EDIT: ah this is the problem i should solve to make my app start:

bq. Patching: Unable to patch the package for self-singing.
Use a proper developer certificate for signing this package.

AFAIK , self-sign will get you only basic capabilities.
which are :
@LocalServices
Location
NetworkServices
UserEnvironment
ReadUserData
WriteUSerData@

You might need developer or symbian certificates for extended capabilities.
