Buldozer / Python for android error: _event.so" is too small to be an ELF executable

[Tom Geiger]

Hi all,

i wrote a Kivy app that i used to package for android the old way with distribute.sh and build.py. I was using Kivy 1.7.2 and although it was not too convenient i managed to run it on my phone.
Now that i updated to Kivy 1.8.0 I tried bulldozer, and while the apk-package is actually built, i cannot run it in android. In logcat, the errror looks as follows:

Appenrently, there's something wrong with the _event.so file. When i checked my old dist - folders, i noticed that this file has always been 0 byte.

So I tried the old way, running 

./distribute.sh -m "sqlite3 kivy" 

but unfortunately i can't get it to work either:

collect2: ld returned 1 exit status

I installed the libpng ubuntu package, and also tried ./distribute.sh -m "sqlite3 png kivy" with no success.

Any ideas on how to solve these issues (especially the bulldozer method, as i think it's a great improvement)

cheers

# 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 

[Ben Rousch]

I can't find any problem and can't replicate it using the current stable buildozer. My only advice is to uninstall buildozer, delete  ~/.buildozer, delete the .buildozer dir in your project, re-install buildozer, and try it again.

There must be some problem with my underlying Ubuntu / Python installation. I tried it on a different computer and there was no error, the package was built and worked.

Thanks

[Ben Rousch]

That's interesting. Could you give some more details about your setup (Ubuntu version, Python version, how you installed Kivy)?

First i had installed kivy using the 1.8.0 tarball and "sudo python setup.py install", the same way i did with the 1.7.2 package earlier. Afterwards I tried the python-kivy ubuntu package with the same results.

I'm using Ubuntu 12.10. 

Python 2.7.3 (default, Feb 27 2014, 19:37:34) 

[GCC 4.7.2] on linux2

[INFO   ] Kivy v1.8.0

>>> cython.__version__

'0.20.1

I attached the verbose output from the buildozer build process, maybe there's some information in it that you can use.
Since I have used Python in many different projects, it might just be the case that i misconfigured it in some place in the course of time.

Hi,

I am facing this same issue. I have tried both buildozer and python for android (not that it would have made any difference, but I can confirm that P4A had been working previously). With both, I get the spit the following error:

I/python  (20467):  ImportError: dlopen failed: "/data/data/org.test.tst/files/lib/python2.7/site-packages/kivy/_event.so" is too small to be an ELF executable
I/python  (20467): Python for android ended.

I also had a linker problem and symbols not being read correctly when I tried P4A. I was able to solve that by upgrading my NDK from r7 to r9.

Thanks,

Gaurav

[Gaurav Trivedi]

I have created https://github.com/kivy/python-for-android/issues/234 to track this issue.

Gaurav

[Gaurav Trivedi]

My issue got resolved when I updated my OSX to 10.9.2 along with the new developer tools.

@Tom: If you are on Mac, I am guessing one of the updates in between broke something.

Gaurav

[Tom Geiger]

Gaurav, thanks a lot for investigating the issue in https://github.com/kivy/python-for-android/issues/234

It helped me to get rid of the error by deleting the P4A_kivy_DIR Variable in my .bashrc file. The app runs fine now. 

[Gaurav Trivedi]

Tom, Akshay (quanon) has further narrowed this issue. You can work around this issue by deleting the build/ directory from your  P4A_kivy_DIR
every time you create a distribution. Make sure you clean your P4A directory (builds and dists) as well before you do this the first time.

I think they are working on a fix for this and create a PR soon.

I have the same error and I
deleted the P4A_kivy_DIR variable from .bashrc,
executed "source ~/.bashrc",
deleted the .buildozer directory from my project and
issued "buildozer android debug".
And I still have the same error.

[Ben Rousch]

After removing the P4A_kivy_DIR you may need to restart your console session for it to take effect.
