How to detect an app installed or not by appuid or name?

Hi, as title. How to detect an app installed or not by appuid or name?

As usual, our wiki would have ready made examples for this use case: [url]http://www.developer.nokia.com/Community/Wiki/How_to_discover_all_installed_applications[/url]

Thank you, Are there any APIs in OS link these:

TBool IsAppExist(TUid app_id);

TBool IsAppExist(const TDesC &app_name);

basically you you need to code those yourself, though it should be really not hard at all.

For the first one you can use RApaLsSession::GetAppInfo.
