buildozer - How do I specify module ?

[Iain Simpson]

I have just started trying to transfer my first working kivy program from Linux (Linux Mint 18 (Ubuntu 16.10)) to android.

I've got buildozer to install app on tablet(Kindle fire hd 7") but it fails when I try to run.

using  buildozer android logcat

I get :

which seems to indicate that it is looking for KivyCalendar.

This module is loaded as normal  - in './usr/local/lib/python2.7/dist-packages/KivyCalendar'

"version = '0.1' 

from kivy.app import App

from kivy.uix.boxlayout import BoxLayout

from kivy.uix.stacklayout import StackLayout

from kivy.uix.floatlayout import FloatLayout

from kivy.uix.relativelayout import RelativeLayout

from kivy.uix.label import Label

from kivy.properties import ObjectProperty, ListProperty, StringProperty, NumericProperty

from kivy.network.urlrequest import UrlRequest

from kivy.uix.listview import ListItemButton

from kivy.factory import Factory

from KivyCalendar import DatePicker

from kivy.core.window import Window"

Do I need to specify it in some other way ?

Sorry if this is an elementary problem but I'm still finding my way around the documentation

Thanks

Not sure without seeing the content of your buildozer.spec but looks like you were missing to add the KivyCalendar package to your requirements setting.

I am attaching buildozer.spec

I haven't done anything special for KivyCalendar as a I assumed that it would be picked up from  the python 'library' ('./usr/local/lib/python2.7/dist-packages/KivyCalendar'.

This is where I feel that I'm missing something fundemental.

Can someone point me at  a suitable document/tutorial ?

Thanks for your help

buildozer doesn't know about or use anything from your local python installation, as it is building a new python distribution for the Android environment. As such, you must tell it about all packages you want to include. If the package is pure python and available on pip, you can include it in the requirements line of buildozer.spec.

[Iain Simpson]

Thanks Alexander - that makes sense

I added KivyCalendar to requirements line

Enter code here...

# (list) Application requirements

# comma seperated e.g. requirements = sqlite3,kivy

requirements = kivy,KivyCalendar

but I now get 

Enter code here...# Cwd /home/iain/Data/iain/workspace/kivy/2nd_attempt/.buildozer

Collecting KivyCalendar

  Using cached KivyCalendar-0.1.3.tar.gz

Collecting kivy (from KivyCalendar)

    Complete output from command python setup.py egg_info:

        Cython is missing, its required for compiling kivy !

       

    Traceback (most recent call last):

Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-K0It5D/kivy/

# Command failed: pip install --target=/home/iain/Data/iain/workspace/kivy/2nd_attempt/.buildozer/applibs KivyCalendar

Earlier in the log  (attached as log1201.txt) it confirmed that cython was found at '/usr/bin/cython'

googling finds a number of references to (spurious?) 'No module named Cython.Distutils' messages but no definate cure.
