I have similar one, when u got a solution, would u mention me pls

[AHiXilTOr]

@xxxkvastarasxxx
requirements = Cython==0.29.33
p4a.branch = release-2022.12.20

[xxxkvastarasxxx]

That is what I have in my buildozer.spec file

title = Test App
package.name = testapp1

package.domain = org.test
source.dir = .

source.include_exts = py,png,jpg,kv,atlas,data,ep,ico
source.branch = release-2022.12.20

version = 0.1

requirements = python3==3.7.6,hostpython3==3.7.6,cython==0.29.33,kivy,kivymd==1.1.1,pillow

presplash.filename = %(source.dir)s/data/presplash.jpg
icon.filename = %(source.dir)s/data/icon.ico

orientation = portrait

osx.python_version = 3.7.6
osx.kivy_version = 1.9.1

fullscreen = 1

android.permissions = android.permission.INTERNET,android.permission.WRITE_EXTERNAL_STORAGE,android.permission.READ_EXTERNAL_STORAGE

And the message that appears after compilling.
As you can see, I have added the cython version and the branch and still have a problem.
Any other recommendations or advices.
Would be grateful!!!

I ran into the same issue and the proposed fix worked for me. Though I can now build the APK, when it runs on device it crashes and shows log:

01-31 15:39:59.601 14315 14348 I python  : Python for android ended.

Is this as simple as specifying requirements = kivy==2.1.0,... in buildozer.spec?

Edit:
Fix was to pin kivy==2.2.0 in my case.
