    Launcher App / UID questions

    Hi,

    I'm developing a launcher-style application. I now have some questions about the return value of
    so.IAppManager.GetList(criteria).

    I get the following result (abridgment):

    Code:
    CAPTION | UID | SHORTCAPTION
    Custom Dictionary|0x2002bc8a|Custom Dictionary
    MCSInstaller|0x2002abde|MCSInstaller
    Communicator|0x2002b425|Communicator
    MCSAppServer|0x2002abe2|MCSAppServer
    MCSStartupClient|0x2002abda|MCSStartupClient
    mcsContacts|0x2002abdc|mcsContacts
    McsConfiguration|0x2002abdd|McsConfiguration
    Communicator|0x2002acd3|Communicator
    MCSUninstaller|0x2002abdf|MCSUninstaller
    COUPIES|0x2004acbe|COUPIES
    Opera Mini|0x2002ee59|Opera Mini
    World Of Rabbit|0x20044de9|WOR
    Vlingo - Voice|0x2001f632|Vlingo - Voice
    Hier und jetzt|0x2000e557|Hier und jetzt
    1) Exists there some kind of blacklist? Stuff like MCSInstaller is something a user probably never wants to start up. How can I filter those system apps?
    2) How unique is the UID? Is it the same on every device? Will it be different if the app has another version or language? Because tha apps are displayed with their local name, e.g. "Hier und jetzt" is "Here and now" on other devices. Will I be able to find the app on an English device, using the Caption or UID displayed here?
    3) Can I somehow access the application icons?

    Yours,
    Ludger

    Hi Ludger,

    1) You could try filtering by using UserInstalledPackage criteria

    Re: Launcher App / UID questions

    2) UID is expected to remain unchanged within the platform. In other words, an app should have the same UID across all Symbian^3 devices. Ovi store uses UID as one of parameters, to detect if there is a update to app, so different versions are likely to have same UID. So in most cases you can use UID find an app.

    3) Well not in a easy way. You can do it with native Symbian code using CreateAppIconLC, but then you would have to implement API bridge plugin for your widget.
