#    -----------------------------------------------------------------------------
#    List as sections
#
#    You can define all the "list" as [section:key].
#    Each line will be considered as a option to the list.
#    Let's take [app] / source.exclude_patterns.
#    Instead of doing:
#
#[app]
#source.exclude_patterns = license,data/audio/*.wav,data/images/original/*
#
#    This can be translated into:
#
#[app:source.exclude_patterns]
#license
#data/audio/*.wav
#data/images/original/*
#


#    -----------------------------------------------------------------------------
#    Profiles
#
#    You can extend section / key with a profile
#    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

now you will better understand my problem.

Edit: After your new suggestion about error, it gives new error in buildozer logcat, it crash my app. Following below is log which got during application launch on device.

I think it is error of debugging, but how can i solve this.

Answer 1

The error is clear, it tries to extract egg to a folder that it doesn't have permission to write to.

Python .egg is this, however it seemed kind of weird that other packages work and this one somehow... doesn't.

I looked at its code and it's not pure-python however and as I see the recipe's comment, the author mentioned that the recipe creates an egg and doesn't install it.

You can look at other recipes, find what's missing and test it. If it runs, the recipe should be ok. Try add -v at the end of this line as I find it in some packages containg C code.

Edit:

I maybe found a way(or two) how to do this without .egg file. I haven't tried it yet because I don't have VM right now. Read this answer. Make a backup of the recipe you have in your buildozer's p4a installation and then edit the netifaces recipe:

change this to:

try $BUILD_hostpython/hostpython setup.py install -O2 --prefix $BUILD_PATH/python-install --old-and-unmanageable

If it doesn't work, then try to make a different change to the recipe. Change this to:

try $BUILD_hostpython/hostpython setup.py build_ext --inplace

then run buildozer, let it create the app, but do not play with it yet. Go through the .buildozer folder(I think?) where p4a installation should be(if not, then look into home/ folder maybe .python-for-android will be there). You need to find the source code for netifaces, because that should now contain compiled stuff(.o and/or .so files).

If you find them, then it's the folder you want. Copy the whole netifaces folder that contains compiled files to your app's folder, delete netifaces from requirements in .spec and run the buildozer again. Hopefully it'll work.

For each recipe change you should clean the cached files of the netifaces package, because it will contain old files and probably even the .egg file.

Also you should check IRC, maybe someone had the same problem or knows how to fix that recipe.
