Kivy crashes on Android: ImportError: dlopen failed: library "libpython3.7m.so" not found #2237

Description

This line works OK on the computer and in several Phones: def open_settings(self): from controller.settings import Settings

On a Huawei that line throws the following error on ADB logcat: 06-12 19:39:53.265 10723 10762 I python : ImportError: dlopen failed: library "libpython3.7m.so" not found

buildozer.spec

Just a standard spec file, nothing special. The same spec file works on other phones.

Command: from controller.settings import Settings

Please the build log and the buildozer.spec, the kivy versions and target Python versions you shared gave me some doubts. Also please try with recent build artifacts and tell us how it runs: https://github.com/kivy/python-for-android/actions/runs/131218787 Try both bdist_test_app_unittests__armeabi-v7a-debug-1.1.apk and bdist_test_app_unittests__arm64-v8a-debug-1.1.apk By the way, these kind of errors that happen only on a given device are usually hard to fix if we can't reproduce it. So if this really happens because of the device, best would be that you investigate and fix it

-----------------------------------------------------------------------------

List as sections

#

You can define all the "list" as [section:key].

Each line will be considered as a option to the list.

Let's take [app] / source.exclude_patterns.

Instead of doing:

#

[app]

source.exclude_patterns = license,data/audio/.wav,data/images/original/

#

This can be translated into:

#

[app:source.exclude_patterns]

license

data/audio/*.wav

data/images/original/*

#

-----------------------------------------------------------------------------

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

From the log

  • master b1f6064d [origin/master] Release 2019.10.06 (#1998)

From the .spec

(str) python-for-android branch to use, defaults to master p4a.branch = master

This is a really old version of p4a, not the master version. Explains why the the message is Python3.7 not Python 3.8

But not why the message occurs, or why 'master' is not 2020.6.2

misl6 commented 1 year ago

Closing as the issue looks related to an old version of python-for-android (we're now targeting Python==3.10)

To the original author: feel free to re-open the issue if it persists with the new python-for-android release.
