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

Import per project custom build rules if present at the root of the project. 
This is the place to put custom intermediary targets such as: 
-pre-build 
-pre-compile 
-post-compile (This is typically used for code obfuscation. 
Compiled code location: ${out.classes.absolute.dir} 
If this is not done in place, override ${out.dex.input.absolute.dir}) 
-post-package 
-post-build 
-pre-clean 
--> 
<import file="custom_rules.xml" optional="true" /> 
<!-- Import the actual build file. 
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.
