 # This file is only used by the Ant script.
 # You can use this to override default values such as
 #  'source.dir' for the location of your java source folder and
 #  'out.dir' for the location of your output folder.
 # You can also use it define how the release builds are signed by declaring
 # the following properties:

 #  'key.alias' for the name of the key to use.
 # The password will be asked during the build when you use the 'release' target.

         Here are some properties you may want to change/update:
         source.dir
             The name of the source directory. Default is 'src'.
         out.dir
             The name of the output directory. Default is 'bin'.
         For other overridable properties, look at the beginning of the rules
         files in the SDK, at tools/ant/build.xml
         Properties related to the SDK location or the project target should
         be updated using the 'android' tool with the 'update' action.

         To customize existing targets, there are two options:
         - Customize only one target:
             - copy/paste the target into this file, *before* the
               <import> task.
             - customize it to your needs.
         - Customize the whole content of build.xml
             - copy/paste the content of the rules files (minus the top node)
               into this file, replacing the <import> task.
             - customize to your needs.
