issue doesn't already exist: https://github.com/kivy/python-for-android/issues
I have a short, runnable example that reproduces the issue
I reproduced the problem with the latest development version (p4a.branch = develop)
I used the grave accent (aka backticks) to format code or logs when appropriated

This looks like it is the same issue as #2675. It looks like matplotlib needs to have need_stl_shared=True in its recipe, so that the c++ runtime library is installed.

This looks like it is the same issue as #2675. It looks like matplotlib needs to have need_stl_shared=True in its recipe, so that the c++ runtime library is installed.

Hi, thank you for your help! Could you specify which file I need to change? at what location?

tcaduser · 2023-10-22T18:28:11Z

If you are installed in a virtual environment, look in $VIRTUAL_ENV/lib/ for the pythonforandroid/recipes/matplotlib/__init__.py and put:

need_stl_shared=True

with the other global variables in the recipe class. If that fixes your problem, please consider making a pull request so others can benefit from it.

tcaduser · 2023-10-22T18:36:33Z

Actually my suggestion might not work at all, since matplotlib is a C++ recipe, and it should be including the library already

RobertFlatt · 2023-10-23T05:29:19Z

Read the last paragraph here https://github.com/Android-for-Python/Android-for-Python-Users#install

The error reported is (failing to report) a memory usage error.
While what looks like an NDK limitation "should" not happen, the real issue may be memory usage.
Look for Python variables storing C memory references being garbage collected.
If in doubt use Python class variables not local variables.

shixiangheng · 2023-10-23T19:40:13Z

If you are installed in a virtual environment, look in $VIRTUAL_ENV/lib/ for the pythonforandroid/recipes/matplotlib/__init__.py and put:
need_stl_shared=True
with the other global variables in the recipe class. If that fixes your problem, please consider making a pull request so others can benefit from it.

Yes, this one solved my problem I think. I changed the recipe.py file with "need_stl_shared=True". I also added this in the init.py file. I can see the canvas now after opening the app, so I believe the matplotlib dependency's problem is solved.

josh140520 · 2023-12-15T03:41:16Z

were to write this need_stl_shared=True in init.py? just anywere?

tcaduser · 2023-12-15T04:16:03Z

this would be a class variable, not instance variable of one of the recipes. It is already implied by this line:

python-for-android/pythonforandroid/recipes/matplotlib/__init__.py

Line 8 in 0df46c8

class MatplotlibRecipe(CppCompiledComponentsPythonRecipe):

Since it is derived from a class setting that variable:

python-for-android/pythonforandroid/recipe.py

Line 1017 in 0df46c8

need_stl_shared = True

So make sure if matplotlib is in your buildozer.spec, this should be taken care of. If you are not using matplotlib, then you need to find the package failing to set this flag.

josh140520 · 2023-12-15T04:35:17Z

Thanks for the reply; it's well appreciated. Which branch do I need to use? I am currently using the 'develop' branch from my fork in Kivy.

tcaduser · 2023-12-15T04:37:10Z

if you are using matplotlib, this should all just work
