4 | A basic Android application to read serial input from an Arduino that is connected over USB (via a USB on-the-go cable on Android 3.1+).

 5 | 
 6 | # This file is only used by the Ant script.
 7 | 
 8 | # You can use this to override default values such as
 9 | #  'source.dir' for the location of your java source folder and
10 | #  'out.dir' for the location of your output folder.
11 | 
12 | # You can also use it define how the release builds are signed by declaring
13 | # the following properties:
14 | #  'key.store' for the location of your keystore and
15 | #  'key.alias' for the name of the key to use.
16 | # The password will be asked during the build when you use the 'release' target.

17 |              The name of the output directory. Default is 'bin'.

20 |          files in the SDK, at tools/ant/build.xml
21 | 
22 |          Properties related to the SDK location or the project target should

72 |              - copy/paste the content of the rules files (minus the top node)
73 |                into this file, replacing the <import> task.
74 |              - customize to your needs.
