Developers Guideline UIQ C++ and PersonalJava
11 October 2004
• Make sure your AppUi is derived from CQikAppUi (Qikon) and not from CEikAppUi (Uikon).
• Ensure that your application is “theme aware”. Use logical colors to draw application controls and
propagate color scheme change messages through your application.
• Add a large version of your application icon for display in the Applauncher icon view.
• The media server supports MP3 audio files. If your application uses audio files in any format, other than
AMR, then convert them to MP3.
Internal user storage – C: drive
The user storage space (C: drive) is shared across applications without any imposed restrictions, apart
from the space becoming full. Unlike a PC, the user does not need to be aware of the underlying file sys-
tem. Applications will always make sensible choices and store information automatically, simplifying man-
agement of data. Third party applications may implement more complex file management solutions where
required.
Applications and information are placed in the internal storage of the P800, P900 and P910 series in the
factory. This provides sample demonstration, educational, multimedia and fun content so that the P800/
P900 series can be used directly out of the box. Much of this can be deleted by the user in order to make
the space available for personal use. The following may be deleted by the user:
• Sony Ericsson Multimedia Content
(Sound, pictures, video and other files chosen to show off the capabilities of the P800, P900 and P910
series)
• Demonstration application files are available for the P800, P900 and P910 series. These files may be
uninstalled.
•In the P800 series, Chess and Solitaire may be uninstalled if more space is needed.
In the P900 and P910 series these games do not utilise internal user storage.
• Language files (Language is selected at First Startup and Master Reset).
If the user selects any language other than UK English, the selected language files and UK English are
retained on the C: drive and the other language files are deleted.)
Note: Themes can not be deleted.
Folder view of internal storage
This section explains in more detail how the data is organised on the C: drive.
Beneath each media type and documents, the material on the mobile phone is broken into Folders. For
each named folder in the related application, a folder is created beneath the applicable media type. For
example, if the user creates a ‘My MP3’ folder in the Music player application, a ‘My MP3’ subfolder is cre-
