    12 <concept id="GUID-5F749184-C804-41FC-BA81-038783BDC967" xml:lang="en"><title>Resources</title><prolog><metadata><keywords/></metadata></prolog><conbody>

    13 <p>In Symbian mobile application development, resource files are used for

    14 defining user interface components and visible text. The advantage of using

    15 resource files include:</p>

    16 <ul>

    17 <li><p>making source code shorter and simpler</p></li>

    18 <li><p>saving memory, because text is loaded only when needed</p>

    19 </li>

    20 <li><p>making it easier to implement localization to different language

    21 groups</p></li>

    22 </ul>

    23 <p>A key example of the use of resource files is found in the implementation

    24 of <xref href="GUID-F3262DF6-39CA-4E96-AD0E-C1FFDE9B0A61.dita">AVKON components</xref>.

    25 AVKON UI components consist of data structures that are defined in the <xref href="GUID-D76B1001-BAF5-4557-A07E-61065523ECBE.dita">resource files</xref>, and

    26 then are called from the classes controlling the UI implementation. When UI

    27 component implementation is split into these two approaches, it means that

    28 resources can be recompiled, for example for new languages, without having

    29 to recompile the application code.</p>
