With the Qt SDK 1.2 it is now easier to install and take into use the In-Application Purchase API available for the Symbian^3 and later devices. This article will illustrate the installation steps.
The installation of the In-Application Purchase (IAP) API relies on Qt SDK's new feature called multiple repository support. While the API is not part of SDK's initial content, and is traditionally delivered as a zip file to be unpacked into the new SDK, the new solution allows its deployment using the familiar SDK install process by simply pointing the SDK to an additional repository, hosted by Nokia Developer.
The most important information is therefore obviously the URL where this repository can be found, so we're starting with providing it. The IAP repository is hosted at http://nds2.fds-forum.nokia.com/extras/inapppurchase/repository ( no trailing / ). To simplify things, and since the installer framework can handle HTTP redirects, you can also use the tiny URL http://tinyurl.com/repoiap (again, no trailing /).
That being said, here are the steps:
1) If you are installing a new instance of the SDK using the online installer, open installer's "Settings" which are available in the first screen of the install wizard. If you already have the SDK installed but want to add this new API, start SDK's maintenance tool and select the Package manager (you may want to apply whatever SDK updates are available first).
2) Add the new repository URL as illustrated below (note that no username and password are required).
3) Close the Settings dialog and with the "Package manager" option selected, move to the "next" step
4) In the Components listing view, you can select (or deselect if you want to unstall it) the In-Application Purchase API (beta) component.
5) Press "next" and you can now see the list of selected components, which should include also the IAP packages listed below
6) Confirm the selection by pressing next and have the content installed.
The installer will copy Examples, Documentation and API package at the correct location so that the new API is ready to use.
Note: as full support for the Symbian tool chain is only available in the Qt SDK release for Windows, the setup has not be tested on Linux and MacOS.
