Bootstraps
|
|
==========
|
|
|
|
This page is about creating new bootstrap backends. For build options
|
|
of existing bootstraps (i.e. with SDL2, Pygame, Webview etc.), see
|
|
:ref:`build options <bootstrap_build_options>`.
|
|
|
|
python-for-android (p4a) supports multiple *bootstraps*. These fulfill a
|
|
similar role to recipes, but instead of describing how to compile a
|
|
specific module they describe how a full Android project may be put
|
|
together from a combination of individual recipes and other
|
|
components such as Android source code and various build files.
|
|
|
|
This page describes the basics of how bootstraps work so that you can
|
|
create and use your own if you like, making it easy to build new kinds
|
|
of Python project for Android.

Creating a new bootstrap
|
|
------------------------
|
|
|
|
A bootstrap class consists of just a few basic components, though one of them must do a lot of work.
|
|
|
|
For instance, the SDL2 bootstrap looks like the following::
|
|
|
|
from pythonforandroid.toolchain import Bootstrap, shprint, current_directory, info, warning, ArchAndroid, logger, info_main, which
|
|
from os.path import join, exists
|
|
from os import walk
|
|
import glob
|
|
import sh
|
|
|
|
|
|
class SDL2Bootstrap(Bootstrap):
|
|
name = 'sdl2'
|
|
|
|
recipe_depends = ['sdl2']
|
|
|
|
def run_distribute(self):
|
|
# much work is done here...
|
|
|
|
|
|
The declaration of the bootstrap name and recipe dependencies should
|
|
be clear. However, the :code:`run_distribute` method must do all the
|
|
work of creating a build directory, copying recipes etc into it, and
|
|
adding or removing any extra components as necessary.
|
|
|
|
If you'd like to create a bootstrap, the best resource is to check the
|
|
existing ones in the p4a source code. You can also :doc:`contact the
|
|
developers <troubleshooting>` if you have problems or questions.
