Closes #3020

First step towards: https://github.com/orgs/kivy/discussions/38
#3013

Updating python to 3.13 removes distutils, so we can't run setup.py directly so all recipes has to be ported to PyProjectRecipe.

  • Introduces a new way to build only recipes using pythonforandroid.recipebuild.

Hey, how is development on this going, and is your version ready to build something? Because I tried using this version, as I really want to build my app using pydantic and openai but that doesn't work because the hashes are missing. Using your version and changed recipes I can build anything, but kivy itself, giving an output that is very long but boils down to this:

I am bit inactive on github due to some other things going on. This PR works on my system, kivy latest recipe isn't ported yet. I will work on it this week.

Wow, thanks for the quick response! The PR works, and I do get compilation working without kivy working (only in the recipe folder and not in requirements) but as soon as I add kivy to requirements it stops working. Sadly I have no idea how recipes work so I probably can't fix it myself. I'll still look at it.
Thanks for the quick reply and thanks a lot if you do end up getting it to work.

Sorry but I don’t seem to understand what you are suggesting/how this is relevant.

Update: So using the old pull directory as source dir (before the update of the kivy recipe, just before posting my initial error message) , I get the first error, but pulling again (using git clone -b prebuilt-artifacts https://github.com/T-Dynamos/python-for-android.git p4a/ I get the second error (both with updated recepies from the newer repo)

I just looked through the differences between the two directories locally, and honestly, I have no Idea what might make such a massive difference.

#-----------------------------------------------------------------------------
#   Notes about using this file:
#
#   Buildozer uses a variant of Python's ConfigSpec to read this file.
#   For the basic syntax, including interpolations, see
#       https://docs.python.org/3/library/configparser.html#supported-ini-file-structure
#
#   Warning: Comments cannot be used "inline" - i.e.
#       [app]
#       title = My Application # This is not a comment, it is part of the title.
#
#   Warning: Indented text is treated as a multiline string - i.e.
#       [app]
#       title = My Application
#          package.name = myapp # This is all part of the title.
#
#   Buildozer's .spec files have some additional features:
#
#   Buildozer supports lists - i.e.
#       [app]
#       source.include_exts = py,png,jpg
#       #                     ^ This is a list.
#
#       [app:source.include_exts]
#       py
#       png
#       jpg
#       # ^ This is an alternative syntax for a list.
#
#   Buildozer's option names are case-sensitive, unlike most .ini files.
#
#   Buildozer supports overriding options through environment variables.
#   Name an environment variable as SECTION_OPTION to override a value in a .spec
#   file.
#
#   Buildozer support overriding options through profiles.
#   For example, you want to deploy a demo version of your application without
#   HD content. You could first change the title to add "(demo)" in the name
#   and extend the excluded directories to remove the HD content.
#
#       [app@demo]
#       title = My Application (demo)
#
#       [app:source.exclude_patterns@demo]
#       images/hd/*
#
#   Then, invoke the command line with the "demo" profile:
#
#        buildozer --profile demo android debug
#
#   Environment variable overrides have priority over profile overrides.
