Python-for-android: error building compiled components in netifaces

Created on 18 Dec 2018 · 7Comments · Source: kivy/python-for-android

Versions

Python: 2.7.13
OS: Buildozer VM
Kivy: 1.10

Description

I run into errors when i try to build an apk. The errors occur during the compilation of netifaces. without including netifaces as a requirement in buildozer.spec file the apk build process goes to completion, which confirms that the error is as a result of compling netifaces.

buildozer.spec

Command:
```buildozer android debug


Spec file:
Requirement from buildozer.spec file

requirements = python2,kivy==master,git+https://gitlab.com/kivymd/KivyMD.git,netifaces

Yes netifaces recipe seems pretty unmaintaned, last commit is from summer 2016 96edc06.
It's even disabled in Travis: https://github.com/kivy/python-for-android/blob/5f66527/ci/constants.py#L40
So contributions to fix it are welcome :smile:

We should fix netifaces or just remove the recipe. If the project is really not active any more, probably the latter.

oh my! I would prefer we fix it please. that's the only library i know of that i can use to get the IP address from an android device. Using netifaces on PyDroid, does exactly what i want. PyDroid is a python interpreter for android devices.

We still accept pull request contributions @princeIta :smile:

@AndreMiras, I think that netifaces should work now, at least the compilation issues should be gone, it was fixed in here: https://github.com/kivy/python-for-android/pull/1549

@princeIta, please, can you check again if netifaces works for you and close this issue if that it's the case? I just made a build with netifaces and python2 without problems...

Note: be aware that you need to change your android's ndk to version r17c...also you should check the following variables in your buildozer.spec file:

android.api = 28
android.minapi = 21

I see that your minapi is set to 19, and that was for the old python recipe...now we use 21 (that it's important because otherwise you will not be able to successfully build the python recipe).

Thanks @opacam I confirm I could build it in Docker with the following command:

python setup_testapp_python3.py apk --sdk-dir $ANDROID_SDK_HOME --ndk-dir $ANDROID_NDK_HOME --requirements python3,kivy,netifaces

I'm not sure why it's still in the the ci/constants.py however. I'll check if it builds in Travis and PR

Proof it's building in https://api.travis-ci.org/v3/job/488531781/log.txt via https://github.com/kivy/python-for-android/pull/1675
