[buybuyxyz]

Checklist

• the issue is indeed a bug and not a support request
• 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

Versions

• Python:3.8.10
• OS:Ubuntu 20.04
• Kivy:2.0.0
• Cython:0.29.24
• OpenJDK:11.0.11

Description

// REPLACE ME: What are you trying to get done, what has happened, what went wrong, and what did you expect?

buildozer.spec

Command:

buildozer android debug deploy run
// REPLACE ME: buildozer command ran? e.g. buildozer android debug
// Keep the triple grave accent (aka backquote/backtick) to have the code formatted

Spec file:

// REPLACE ME: Paste your buildozer.spec file here
change following lines 

package.domain = org.test1
requirements = python3,kivy,matplotlib
android.archs = arm64-v8a
p4a.branch = develop

Logs

// REPLACE ME: Paste the build output containing the error
// Keep the triple grave accent (a.k.a. backquote/backtick) to have the code formatted

I found a way to avoid the error.

pythonforandroid/recipes/matplotlib/__init__.py

self.ctx.get_site_packages_dir() => self.ctx.get_site_packages_dir(arch),

The same bug is found below files.
pythonforandroid/recipes/cffi/__init__.py
