interesting that python hides itself in an mp3 file on android

Customize your distribution

The basic layout of a distribution is:

AndroidManifest.xml     - (*) android manifest (generated from templates)
assets/
    private.mp3         - (*) fake package that will contain all the python installation
    public.mp3          - (*) fake package that will contain your application
bin/                    - contain all the apk generated from build.py
blacklist.txt           - list of file patterns to not include in the APK
buildlib/               - internals libraries for build.py
build.py                - build script to use for packaging your application
build.xml               - (*) build settings (generated from templates)
default.properties      - settings generated from your distribute.sh
libs/                   - contain all the compiled libraries
local.properties        - settings generated from your distribute.sh
private/                - private directory containing all the python files
    lib/                  this is where you can remove or add python libs.
        python2.7/        by default, some modules are already removed (tests, idlelib, ...)
project.properties      - settings generated from your distribute.sh
python-install/         - the whole python installation, generated from distribute.sh
                          not included in the final package.
res/                    - (*) android resource (generated from build.py)
src/                    - Java bootstrap
templates/              - Templates used by build.py

(*): Theses files are automatically generated from build.py, don't change them directly !
