Matplotlib issue in android

[Jyoti Patil]

hello all , i have posted this issue on discord but no one is responding...

i am building an visual speech app for android . the app runs properly on desktop but its gets crash on android. It gives me issue for matplotlib.

I am using kivy garden's matplotlib 3.2.1 version , kali linux . i am attaching my log and .spec files here also. Is there anyone who have used matplolib in android?

Please help me why its happening to me..does buildozer doesnt supports matplotlib?

or there is any alternative for matplotlib in kivy?

Thanks in advance.

#
#[app]
#source.exclude_patterns = license,data/audio/*.wav,data/images/original/*
#
#    This can be translated into:

#[app:source.exclude_patterns]
#license

#


#    -----------------------------------------------------------------------------
#    Profiles
#
#    You can extend section / key with a profile
#    For example, you want to deploy a demo version of your application without
#    HD content. You could first change the title to add "(demo)" in the name
#    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

I suspect the issue is the version of matplotlib specified in the buildozer.spec

The recipe is for a different version, see line 11 in :

https://github.com/kivy/python-for-android/blob/develop/pythonforandroid/recipes/matplotlib/__init__.py

You can probably test this assumption by removing the version in the .spec, then buildozer appclean, buildozer android debug.

Presumably this version is specified for a reason, your options are:

1) change the app to use the recipe version

2) modify the recipe to build the matplot version you want. Do this by creating a local copy of the recipe, and make any required changes.

    I don't know the scope of the required changes, presumably at a minimum it would be the patch files.

I have made an apk with matplotlib and kivy but when I am running it is crashing I have attached logfile and buildozer.spec files also any body who can help??

[Degenerate Tech]

connect your phone to computer and turn on debug mode

run
adb logcat *:S python:D

then open your app in android
put all log

[Robert Flatt]

The way to debug this is to look in that log file for "Traceback", you will find the Python stack trace:

10-10 12:15:36.474 29371 29575 I python  :  Traceback (most recent call last):

10-10 12:15:36.478 29371 29575 I python  : Python for android ended.

So it is something about the way the app imports garden.matplotlib

Personally I make a local copy of garden.matplotlib (suitably edited) and it works just fine.

Possibly you did that, but didn't follow all of the instructions?  https://groups.google.com/d/msg/kivy-users/Muf26gVO7l0/XttmJ6BQBgAJ
