ImportError when the apk launches with SDL2 bootstrap, kivy and python3crystax #658

haricot · 2016-03-02T09:05:57Z

I do not know if it actually works, but in my case it does not work with android 5.0. And I'd like to know why :-) (the apk works well with sdl2, Kivy, python 2)

Maybe it's a bug
python3.5 https://bugs.python.org/issue12029
python3.6 https://bugs.python.org/issue25537

Can we apply a patch python3crystax?

inclement · 2016-03-03T23:14:13Z

I'm not sure what's wrong here - it could maybe be the bug in python, but I know the python3 with crystax can work and the error isn't with any custom code which I haven't tested.

There's currently a bug with python3crystax and kivy that could maybe manifest this way, involving being compiled with the wrong python. Could you try building with kivy 1.9.1 (not the master branch, as is the default) - I think you should be able to use 'kivy==1.9.1' in the requirements, though you'll also need to make sure everything is rebuilt (you can do p4a clean_all first to be sure)?

Thank you for your answers.
I follow your instructions but I get the same result.

inclement · 2016-03-03T23:47:35Z

Interesting that it's a different symbol it can't find. I think maybe it more generally has failed to find/load the python3 .so file. I haven't tried the build for a while, but I'll see if I can reproduce it (it could be a few days before I have time though).

If you'd like to investigate, I'd start by checking the java bootstrap code and finding a way to check if it's loading python3.5m.so correctly. There may be a log message about this already, but I don't remember the format. If it isn't loading it, that is probably the problem.

haricot · 2016-03-04T00:08:26Z

Yes you are right, i went a little fast, this is not the same result.
With Kivy==1.9.2
cannot locate symbol "PyErr_GivenExceptionMatches"

and with kivy==1.9.1
cannot locate symbol "PyObject_GetAttr"

I looked where the files .so point with my phone root and it seemed to be the right place but I may be wrong.

inclement · 2016-03-04T00:15:14Z

It's the libpython3.5m.so that's important - did you find that one? And even if it's there (in the libs/armeabi folder), the important question is probably if it's loaded by the java bootstrap.

haricot · 2016-03-04T00:31:33Z

I do not know if the libpython3.5m.so and finally fully charged by the bootstrap Java.

Perhaps we must add a few things as below to the bootstrap sdl2 _event.so) work ?
( python-for-Android/pythonforandroid/bootstrap/sdl2/build/jni/src/start.c)
(kivy/kivy/_event.pyx ( _event.so))

#Presentation EuroPython 2012: C++ APIs on Python

#Exception translation
PyObject *t, *v, *tb;
PyErr_Fetch(&t, &v, &tb);

// Check if it's a ValueError
if (PyErr_GivenExceptionMatches(

    value_error_class_obj, t))
{
 throw ValueError();
}

Have you a clues for to invest bootstrap sdl and libpython3.5m.so ?

haricot · 2016-03-30T20:55:18Z

it is good it works :-)
He was the llibpython3.5m.so who has not been charged

I added this to the setup.py file Kivy

      if PY3:
            e.extra_link_args += ['-lpython3.5m']

and this to the setup.py file pyjnius:

I'm having the same problem with my kivy app on android (built on ubuntu), so it's great this is fixed! I'm using python-for-android - can someone please spare a few minutes to tell me how I merge the fix?

haricot · 2016-04-12T08:09:16Z

@m-mcgowan This bug does not appear on distributions based on Archlinux.
The pull resquests that I proposed are not ideal because it must be placed in rather p4a.
(To test you simply apply the above modif to your Kivy packages and Pyjnius (.local/share/python-for -android/packages/))
I reinstalled a distribution based on Debian but for now I do not own solution and that it works without modif on Archlinux distributions confuses me a little.

I think the bug comes from python-3.5 on Debian based,
because BLDLIBRARY is set to a static lib.

Debian
~$ python3.5 -c "import distutils.sysconfig; print(distutils.sysconfig.get_config_var('PY_ENABLE_SHARED'))"
None
~$ python3.5 -c "import distutils.sysconfig; print(distutils.sysconfig.get_config_var('BLDLIBRARY'))"
-lpython3.5m

~$ python3.2 -c "import distutils.sysconfig; print(distutils.sysconfig.get_config_var('PY_ENABLE_SHARED'))"
None

~$ python3.2 -c "import distutils.sysconfig; print(distutils.sysconfig.get_config_var('BLDLIBRARY'))"
-L. -lpython3.2mu

Archlinx
~$ python3.5 -c "import distutils.sysconfig; print(distutils.sysconfig.get_config_var('PY_ENABLE_SHARED'))"
1
~$ python3.5 -c "import distutils.sysconfig; print(distutils.sysconfig.get_config_var('BLDLIBRARY'))"
-L. -lpython3.5mu

So I think it needs to be patched python3.5 for debian based but the easiest might be to add temporary patches recipes for Kivy and pyjnius.

In recipes of kivy and pyjnius
(if recipe is for version python3crystax==3.5)( here (if) I don't know how do)

#patch because BLDLIBRARY is set to a static lib with some distributions
    try:
        py35 = sh.Command('python3.5')
        cmdline = shprint(py35, '-c', "import distutils.sysconfig; \
        print(distutils.sysconfig.get_config_var('BLDLIBRARY'))")
        cmdlineout=str((cmdline.stdout).decode("utf-8"))
        if cmdlineout=='-lpython3.5m\n':
            patches=['set_extra_link_args_35.patch']
    except:
       sys.stdout.write("your BLDLIBRARY is already good ! ")

set_extra_link_args_35.patch (in recipe kivy)
("if PY3" is not needed if version of python3crystax==3.5 in recipes)

Nice detective work. I don't have a debian-based install, but if you or anyone else would like to make a PR to fix it, it should be great to merge it.

(I suspect the real issue is the way p4a calls python3, which is a bit hacky, so maybe eventually changing that would also fix things).

Hi,
I got bit by the same bug and applied the proposed patches to add "-lpython3.5m" to kivy and pyjinus with the same results as above.

However, as above, it just fails with an other error :

I/python (31712): [ERROR ] [Input ] AndroidJoystick is not supported by your version of linux
I/python (31712): Traceback (most recent call last):
I/python (31712): File "/data/data/org.hello.world/files/crystax_python/site-packages/kivy/input/providers/androidjoystick.py", line 17, in

I/python (31712): ImportError: No module named 'android'
I/python (31712): During handling of the above exception, another exception occurred:

I/python (31712): raise Exception('android lib not found.')
I/python (31712): Exception: android lib not found.

I tried to fix this by adding 'android' to the list of requirements, but that opened a new can of worm ☹.
Has anyone had a working kivy apk with python3.5 built from a Debian based system ?
Any help would be greatly appreciated !

The exact same thing is happening here under Ubuntu 16.04. As with Debian, BLDLIBRARY is set to a static lib, and making the above patches to eliminate the _clock.so and _event.so errors results in android lib not found.

I think this is probably fixed by ed1e1a8
