      <td>Layout Direction</td>

      <td>Examples:<br/>

        <code>ldrtl</code><br/>

        <code>ldltr</code><br/>

      </td>

      <td><p>The layout direction of your application. {@code ldrtl} means "layout-direction-right-to-left".

      {@code ldltr} means "layout-direction-left-to-right" and is the default implicit value.

      </p>

      <p>This can apply to any resource like layouts or values or drawables.

      </p>

      <p>For example, if you want to provide some specific layout for the Arabic language and some

      generic layout for any other "right-to-left" language (like Persian or Hebrew) then you would have:

      </p>

<pre class="classic no-pretty-print">

res/

    layout/   <span style="color:black">

        main.xml  </span>(This is the default layout)

    layout-ar/  <span style="color:black">

        main.xml  </span>(This is the specific layout for Arabic)

    layout-ldrtl/  <span style="color:black">

        main.xml  </span>(This applies to any "right-to-left" language, except for Arabic, because the ar language qualifier has a higher precedence.)
