The following is based on kivy/python-for-android
So currently on Android pyjnius needs sdl so we need to compile sdl first
sdl source can be found here
https://github.com/kivy/python-for-android/tree/master/src/jni/
this is what python-for-android do for sdl :
push_arm <== initialize environment , define in distribute.sh
try ndk-build V=1 <== build
pop_arm <== leave environment
try cp -a $SRC_PATH/libs/$ARCH/*.so $LIBS_PATH
next for pyjnius :
push_arm <== initialize environment , define in distribute.sh
export LDFLAGS="$LDFLAGS -L$LIBS_PATH"
export LDSHARED="$LIBLINK"
# fake try to be able to cythonize generated files
$HOSTPYTHON setup.py build_ext <=$HOSTPYTHON seems to be a local
python binary compiled just before
try find . -iname '*.pyx' -exec $CYTHON {} \; <= $CYTHON is a
system wide installed cython
try $HOSTPYTHON setup.py build_ext -v
try find build/lib.* -name "*.o" -exec $STRIP {} \;
try $HOSTPYTHON setup.py install -O2

If you can identify what steps need to be taken, rather than the
details of how to actually do it, for example...
<br>
<br>
The Cython source file that needs converting to C.
<br>
The C files (generated or otherwise) that need compiling.
<br>
Any .py files that need including.
<br>
Any additional include directories that need to be searched.
<br>
Any additional libraries that need to be linked.
<br>
<br>
I can then see how to add general support for Cython extensions to
pyqtdeploy.
<br>
