Database problem in mobile application

I'm currently using the OfflineStorage API in QML. I changed the OfflineStorage database path using the setOfflineStoragePath() method and declared it as a resource file using a .qrc file.

I'm able to retrieve data from my databases using the Desktop debugger and Qt Simulator. My problem is, whenever I deploy my application and install it in a mobile device (Nokia N8), the program does not retrieve the database values. How come?
