    <!-- Execute the Android Setup task that will setup some properties
         specific to the target, and import the build rules files.

         The rules file is imported from
            <SDK>/tools/ant/
         Depending on the project type it can be either:
         - main_rules.xml
         - lib_rules.xml
         - test_rules.xml

         To customize existing targets, there are two options:
         - Customize only one target:
             - copy/paste the target into this file, *before* the
               <setup> task.
             - customize it to your needs.
         - Customize the whole script.
             - copy/paste the content of the rules files (minus the top node)
               into this file, *after* the <setup> task
             - disable the import of the rules by changing the setup task
               below to <setup import="false" />.
             - customize to your needs.
