Buildozer failing on Arch + questions on building configuration

[Goffi]

Hello,

I'm trying to use buildozer to port our XMPP client to Android. I'm compiling
using Arch Linux with aur/python2-buildozer-git. Note that "python" is Python
3 on Arch, but my application is Python 2.

The build is failing (traceback below), and I have a couple of questions:

1) how can I specify that I want python 2 and not python 3 in my APK ? If I
add python2 in requirements in buildozer.spec is it enough?

2) I have dependencies to local packages, how the requirements work in this
case? Actually is it taking packages (with no recipes) in pypi, or does it
copy it from my PYTHONPATH? My dependencies are pure python, so a recipe
should not be needed.

3) minor point, but buildozer is looking for main.py, can I specify an other
name?

4) I had to specify p4a.local_recipes = ./.buildozer/android/platform/python-
for-android-master/pythonforandroid/recipes in buildozer.spec


5) I have tried to do a build with just a few dependencies (I'm not expecting
to see the app running for the moment, I just want to success to create a
apk), and it's failing with the following trace below (just putting the
interesting part).


Thanks for any help, and for all this great work done :)

1) Just adding python2 in the requirements is fine.

2) requirements without recipes are pulled from pip. There isn't a convenient way to include local packages automatically, but you can just put them in your code folder.

3) python-for-android assumes a main.py entry point. It would be possible (and not hard) to add an option for something else, but nobody has done it. A PR adding this functionality would probably be welcome.

4) Thanks for the report, this is in the process of being fixed.

5) Could you post (or link to a pastebin with) the full log, not just this part?

I've tried to use a symbolic link, it doesn't seems to work neither (would be
a simple workaround). I'm using a bind mount for the moment, it works fine.

yes sure, that should be an easy entry point to the code, I'll check it when I
have some time

yes, I realised than my buildozer.spec was not good (I have made a fresh one
and forgot to change the values), but after doing it I have a different error,
still related to ant:

https://paste.debian.net/857784/

here is the buildozer.spec:

https://paste.debian.net/857786/

thanks!

Hello,

I've tried to install ubuntu version in a Docker image, and I have the same
result (ant related error), with android_new.

Tried to remove .buildozer then build in Ubuntu Docker image with old tool
chain (android), I have an other error, still related to ant:

https://paste.debian.net/858052/

This one seems related to a ticket already open: https://github.com/kivy/
buildozer/issues/406


any help welcome :)

thanks

Oh, I found a bug.

I was intrigued by the following line in buildozer logs:

[aapt] /cagou/src/.buildozer/android/platform/python-for-android/dist/cagou/
bin/AndroidManifest.xml:2: Tag <manifest> attribute package has invalid
character '-'.

after checking I realized it's because I have this in my buildozer.spec:

package.domain = org.salut-a-toi.cagou

by removing the "-" (using an other package.domaine = org.goffi.cagou), the
build seems to work.

Don't have time now to investigate more, but it seems than having dashes in
package.domain breaks the building process.

I have now an .apk in by bin dir (using old tool chain with Ubuntu Docker
image), It can't work has I have removed all dependencies, but it's a big step
in the right direction :)
