Hello.We already develop an app for harmattan that already published in nokia store.We decided to port the app to symbian platform.But the problem is the app wont display anything when opened.We manage to compile it but when tested on c7 device,the app just display blank and empty screenwhen open the app..We already do some modification to qml and rewrite the ui so it complies with symbian ui .The pro. file also already been define with symbian specific qt.The phone also already installed with all latest qt component and qt related.So what do we miss.There also lack of documentation on porting app from harmattan to symbian that could help

Code:
# Add more folders to ship with the application, here
folder_01.source = qml/xxxxxxx
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 = 0xE30E7865

# 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 +=

# Speed up launching on MeeGo/Harmattan when using applauncherd daemon
CONFIG += qdeclarative-boostable

# Add dependency to Symbian components
 CONFIG += qt-components

# The .cpp file which was generated for your project. Feel free to hack it.
SOURCES += main.cpp

# Please do not modify the following two lines. Required for deployment.
