python for android recipe

[Davide Macocchi]

hi guys!
can someone help me writing the recipe to build autobahn module for python-for-android?

If you mean "Scripting Layer for Android" (SL4A), there are some notes
on the

https://github.com/tavendo/AutobahnPython/blob/master/README.md

Any luck with this? I would be curious to know if you managed to get this working and what issues you have run into.

Sorry, I have never tried that myself. Other have (and had success), and
hence this was added to the README ..

Hi everybody, I also try to figure out how I can get a recipe done fore buildozer,
cause I want to use autobahn in a kivy app wich is running on android thru python-for-android.
But now I am stuck...

1. I dont know exactly on wich autobahn depends
2. if i let it compile thru buildozer I got the following error:

running build_ext
Twisted found (default reactor is <class 'twisted.internet.epollreactor.EPollReactor'>)
Twisted dropin.cache regenerated.
running build_ext
Twisted found (default reactor is <class 'twisted.internet.epollreactor.EPollReactor'>)
Twisted dropin.cache regenerated.
find: "build/lib.*": Datei oder Verzeichnis nicht gefunden #File or Folder not found
# Command failed: ./distribute.sh -m "kivy twisted autobahn" -d "btms"
#
# Buildozer failed to execute the last command
# The error might be hidden in the log above this error
# Please read the full log, and search for it before
# raising an issue with buildozer itself.
# In case of a bug report, please add a full log with log_level = 2

I read about that the byte code is not created....


Here is my recip:

#!/bin/bash

VERSION_autobahn=${VERSION_autobahn:-0.10.9}
URL_autobahn=https://pypi.python.org/packages/source/a/autobahn/autobahn-$VERSION_autobahn.tar.gz

function prebuild_autobahn() {
    echo "tty.pyo" >> "${BUILD_PATH}/whitelist.txt"
    echo "termios.so" >> "${BUILD_PATH}/whitelist.txt"
}

function shouldbuild_autobahn() {
    if [ -d "$SITEPACKAGES_PATH/autobahn" ]; then
        DO_BUILD=0
    fi
}

function build_autobahn() {

    cd $BUILD_autobahn

    push_arm
    export LDFLAGS="$LDFLAGS -L$LIBS_PATH"
    export LDSHARED="$LIBLINK"

    export PYTHONPATH=$SITEPACKAGES_PATH:$BUILDLIB_PATH

    # fake try to be able to cythonize generated files
    $HOSTPYTHON setup.py build_ext
    try find . -iname '*.pyx' -exec $CYTHON {} \;
    try $HOSTPYTHON setup.py build_ext -v
    try find build/lib.* -name "*.o" -exec $STRIP {} \;

        try $BUILD_hostpython/hostpython setup.py install -O2 --root=$BUILD_PATH/python-install --install-lib=lib/python2.7/site-packages

    try rm -rf $BUILD_PATH/python-install/lib/python*/site-packages/autobahn/test
    try rm -rf $BUILD_PATH/python-install/lib/python*/site-packages/autobahn/*/test

    unset LDSHARED

    pop_arm
}

function postbuild_autobahn() {
    true
}

Maybe you can point me in the right direction or you get a working one :-)

Thanks !

Hi Jakob

I used autobahn in a kivy app running on android, and got away by having

requirements = kivy,crossbar

in my buildozer.spec. I'm not sure anymore, but I think I did not use

requirements = kivy,autobahn

because I also needed to import inlineCallbacks from twisted.internet.defer.

It appears to me that there is no need for a recipe when using the Twisted-based autobahn/crossbar.io, since there is a recipe for Twisted already.

Thank you Roger for your answer.

I also try it with crossbar in the requirements but this not work. Buildozer draws the following error cause the recipe for crossbar is missing.

If its possible it would be nice when you take a look at your buildozer folder there should be a crossbar folder with a recipe.sh file under and if true poste it please:

.buildozer/android/platform/python-for-android/recipes

Thank you!

Hi Jakob,

you need to take care of the virtualenv issue first (command not found). Then report back again, please.

Cheers,

Roger

Hi Roger,
last night I install buildozer in a virtualenv
like in this tutorial http://www.gurayyildirim.com.tr/howto-install-kivy-and-buildozer-on-ubuntu-15-04-1169.html
installed also twisted, autobahn, crossbar.

Frist I tried with crossbar in the requirements but this raise an error:

Collecting cffi>=1.1.0 (from cryptography>=0.7->pyOpenSSL>=0.11->treq>=15.0.0->crossbar)
  Using cached cffi-1.3.1.tar.gz
    Complete output from command python setup.py egg_info:
   
        No working compiler found, or bogus compiler options
        passed to the compiler from Python's distutils module.
        See the error messages above.
        (If they are about -mno-fused-madd and you are on OS/X 10.8,
        see http://stackoverflow.com/questions/22313407/ .)
   
    ----------------------------------------

Now I got in the requirements = kivy,autobahn,twisted
Build run fine and my app is running on android.

YES :-)

Crossbar or Autobahn dont show up in the recipe folder like i expected but it is packed directly in applibs.

Thank you for your time!
