Proposal: Android-Specific Metadata Support in Recipes #3179
Description
Introduce support in python-for-android to parse Android-specific metadata from pyproject.toml of pip-installed packages. This enables modular bundling of assets into APK builds, allowing packages to contribute platform-native components directly.
Example pyproject.toml Layout
[tool.python-for-android.android]
src = "android/src/"
res = "android/res/"
extra_manifest_xml = "android/extra_manifest.xml"
extra_manifest_application_xml= "android/extra_manifest_application.xml"
activities = [
{
"name": "org.package.android.MyActivity",
"process": ":package_process",
}
]
proguard = "android/proguard-rules.txt"
jniLibs = "android/jni/"
assets = "android/assets/"
resources = "android/resources"
etc. Etc.How It Works
- During dependency resolution (p4a.recipe or pip stage), check for [tool.python-for-android.android] in pyproject.toml.
- Resolve declared paths from the site-packages directory.
- Inject collected files into dists/<your_app>/build/ before Gradle build.
Please consider this.
THANKS!!

@kuzeyron I want to take on this, but I don't know if the approach I have in mind is okay. Here's what I'm thinking: directly under this code:
python-for-android/pythonforandroid/build.py
Lines 528 to 531 in 359975b
p4A can loop through all installed python packages looking for a
android.tomlor in the root folder of each package or inroot/android. When found it loads toml file and extracts the java src file only and copy it toctx.javaclass_dir.The reason I said java src file only is because modifying xml or adding resources can conflict with what the user want's to modify themselves.

Something even better,
--requirementsargs can be modified to accept extra arguments. e.gwhere
androidandjavaare the directory inside the packages containing the java files in a java compliant package directory. then we can extract them and put inenvironjust like the way theversionsare stored inenvironalso. and then copy them toctx.javaclass_dir.@kuzeyron what do you think?

Sure, why not? Make sure to write a proper documentation of this if you proceed with this task.
