csv module

[dcorio]

csv is included in the standard library, but i cannot load the module on android.

adb logcat says this:

I/python (20884): File "/home/enlightx/Development/Kivy/python-for-android/build/python-install/lib/python2.7/csv.py", line 8, in
I/python (20884): ImportError: No module named _csv

It's part of the modules that are blacklisted by default to make the shipping packages lighter, you can safely reactivate it by editing the blacklist.txt file of your python-for-android distribution.

Keep in mind from https://groups.google.com/forum/#!msg/kivy-users/mgisdssF39M/28vgOWfM0y0J that:

There are 2 locations for blacklist.txt, one is inside .buildozer/android/platform/python-for-android/src/ and the other is in python-for-android/dist/distname, the first changes the blacklist for every compilation the other for a specific compilation.

So don't forget to remove it from BOTH. I accomplished that with the following lines in my makefile bash script (my app is called lanki):

# Create the .buildozer folder and download its subcomponents, including the blacklist.txt file we are about to modify
buildozer android update

# Remove the line containing csv so the csv module is installed, as per the warning on
# http://python-for-android.readthedocs.org/en/latest/usage/#step-2-package-your-application
# grep -v reverses the search, showing all lines except the one matching the pattern

# INSTALL CSV module
# This requires removing _csv from the two blacklist files
# According to

cd .buildozer/android/platform/python-for-android/src/
cat blacklist.txt | grep -v "_csv" > blacklist.txt2
rm blacklist.txt
mv blacklist.txt2 blacklist.txt

cd $cwd

cd .buildozer/android/platform/python-for-android/dist/lanki/
cat blacklist.txt | grep -v "_csv" > blacklist.txt2
rm blacklist.txt
mv blacklist.txt2 blacklist.txt

cd $cwd
