SDL error:could not load any libpythonXXX.so

[atheistrepublic]

I have created my application using buildozer.And everything works fine.But the moment i replace:

1)"package.name = myapp" to "package.name = anoop"
2)"package.domain = org.test" to "package.domain = org.singh"
in the .spec file the app crashes on my andoid with the error "An error occured while trying to start the application.Please try again and/or reinstall.
Error: Could not load any libpythonXXX.so".

Note that the when i run buildozer android debug everything works fine its omly that the app crashes on android.
I am attaching the error screenshot.

I suspect you're missing python3 from your requirements. You should share your buildozer.spec at least

The problem is when i change
1)package.name = myapp to package.name=anoop and
2) package.domain = org.test to package.domain = org.singh
the above error appears.
This is my .spec file:

#    Instead of doing:
#
#[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

OK good to know. Maybe try again from a clean build by deleting the project .buildozer/ directory

[atheistrepublic]

I tried that(i.e., deleting the .buildozer directory) and runnig buildozer android debug but the problem remains.

[RobertFlatt]

I filed what I suspect is the same issue under Python for Android:
kivy/python-for-android#2045

[LukasSliacky]

Hm, this is wierd, because in my case this problem start when i renamed package name from "ruscan" to "ruscanapp".
After renamed back to "ruscan" work everything okay.

[borabod]

after installing a release apk, sdl error could not load any libpythonxxx.so
here is what i did and make the release apk work:
in keytools, the 'organization unit' and that of 'organization' you made for your keystore must be same.

example:
What is the name of your organizational unit?
[Unknown]: someorg

and also,

What is the name of your organization?
[Unknown]: someorg
i left the package name as is:

package.name = myapp

copy this on your buildozer.spec:

package.domain = someorg

however i got too excited and change my buildozer spec requirement from python3 to python2 and it still work.. in my case the someorg is just a single word no (dots) in between. No changes on the .py or .kv file..

im really new here at github, please excuse if i made some errors while typing these.

[Masikini]

I just got out of the same issue, i uninstalled what i had previosuly had on my phone and on my linux deleted the spec file and generated a new one. Am able to run the apk on my phone now.

Hi!
Since this is now closed (The other topic) I write it here:
I have the same problem always WHEN I build on the same folder for different platforms one after another.
The workaround that works for me is, after changing the buildozer.spec is easy, I perform a
buildozer android clean
always before
buildozer android debug (or build).

Hope it helps others and maybe to identify the problem.

[Masikini]

Hello Javier Thank you for the explanation. I will simply adopt your way too.

But wait I thought this was fixed recently in kivy/python-for-android#2127
Could you try on p4a.branch = develop?

[AndreMiras]

kivy/python-for-android#2127 was merged into master
