  • Replacepicturewith ENIACAnimatedOviIcon -&gt; Arrow to indicate downloadNokia Smart Installer for Symbian (or Smart Installer, for short) is a tool that ensures that the installed 3rd party applications have always access to the required versions of their dependent libraries. Smart Installer is split into two components: smartinstaller and smartinstaller ADM (for ‘application dependency manager’). Smart Installer is a small component that will be embedded with the application to a wrapper package; it ensures that a recent version of ADM is installed on the device and installs/upgrades ADM, if necessary. Because of the nature of Smart Installer functionality, network connection is always required during installation. See Section 1.2, ‘Smart Installer network usage’, for a detailed description about network usage. Smart Installer is invoked during the application installation process on the Symbian device. It immediately fetches the latest ADM from the server and runs it. ADM checks whether the required components (dependencies) are already installed on the device and downloads and installs, or upgrades them, if needed. Information about the application’s dependencies is extracted from the application sis file, where each dependency is defined using the standard dependency statements as defined in the pkg file format. For Qt, the dependencies are automatically generated during the build process, but developers can manually adjust them as well. After the required dependencies have been successfully installed to the device, the application installation process is invoked. This follows the normal UI flow of application installation on a Symbian device.     1. Select Start &gt; Nokia Qt SDK &gt; Symbian &gt; Qt for Symbian Command Prompt to open a command prompt with the appropriate environment set.    2. Change directory to your project folder.    3. To build the application executable, enter the following command: qmake &amp;&amp; make release-gcce    4. To build and sign your application SIS file with your Ovi Publisher key and certificate, enter the following command:make sis QT_SIS_CERTIFICATE=developer.cer QT_SIS_KEY=developer.keyHere, the publisher certificate and key are located in the current folder. If they are located in another folder, specify the path as well as the filename.    5. To package Nokia Smart Installer with your application and sign it:a. Open the wrapper package in an editor. It will be named &lt;myapp&gt;_installer.pkg.b. Replace the testing UID A000… with the reserved wrapper package UID 0x2002CCCF.c. Replace the “c” in the install file destination path with a “!” and then save the file; eg:&quot;X:/proj/myapp/myapp.sis&quot; – &quot;c:private2002CCCEimportmyapp.sis&quot;&quot;X:/proj/myapp/myapp.sis&quot; - &quot;!:private2002CCCEimportmyapp.sis&quot; d. Then enter the following command: make installer_sis QT_SIS_CERTIFICATE=developer.cer QT_SIS_KEY=developer.key e. A “wrapper” SIS is generated with a name like &lt;myapp&gt;_installer.sis      6. Submit this wrapper SIS file to Publish to Ovi.
