			 the name of your application package as defined in the manifest. Used by the
			 'uninstall' rule.
		 source.dir
			 the name of the source directory. Default is 'src'.
		 out.dir
			 the name of the output directory. Default is 'bin'.

		 Properties related to the SDK location or the project target should be updated
		  using the 'android' tool with the 'update' action.

		 This file is an integral part of the build system for your application and
		 should be checked in in Version Control Systems.

		 and import the build rules files.

		 The rules file is imported from
			<SDK>/platforms/<target_platform>/templates/android_rules.xml

		 To customize some build steps for your project:
		 - copy the content of the main node <project> from android_rules.xml
		 - paste it in this build.xml below the <setup /> task.
		 - disable the import by changing the setup task below to <setup import="false" />

		 This will ensure that the properties are setup correctly but that your customized
		 build steps are used.
