This doesn't seem like a kivy issue, but a py4a issue.

[inclement]

Don't know what has happened here, unless you have set $P4A_kivy_DIR perhaps?

[nitanmarcel]

@inclement Yes, I've set that $P4A_kivy_DIR

[inclement]

@nitanmarcel Aha, in that case I think you're hitting a bug where p4a does not recompile kivy because the setup.py process sees the .so files are already present, and doesn't know that they are for the wrong architecture. I think I'm working around that by deleting kivy/_event.c, which should trigger cython to be re-run without preventing the Kivy install from being used for other stuff.

[nitanmarcel]

@inclement deleted the env variable also the .buildozer folder and the error is still there

[inclement]

Can you do that again, re-run buildozer, and post the full build log?

[nitanmarcel]

@inclement Here is the full console log https://transfer.sh/FqXFs/buildozer.log

[nitanmarcel]

Can you do that again, re-run buildozer, and post the full build log?

After a lot of fights with switching between different versions of p4a and kivy I managed to build using kivy==master . I still have no idea what caused that weird bug and why it's working right now. I will leave this issue open if you need it for future reference.

[windowsansiblernew]

where did you give kivy==master this? in buildozer.spec? i also have the same issue, please help

[TechnoLenzer]

Once I fixed this issue as mentioned above and rebuilt, the 64-bit app crashes upon launch. The logger doesn't specify the error and there's no Traceback, it just says that python-for-android ended. Is there possibly an issue with the imports or would it be with my phone (Huawei P20)?

[inclement]

@TechnoLenzer Please paste the full adb logcat output at the kivy-users mailing list or kivy discord channel.

[HelaFaye]

I just encountered a similar error with android while moving from python2 to python3. Cleaning up after previous builds helps.

[TechnoLenzer]

@inclement The issue wasn't actually anything to do with the change to 64-bit, but it was that the app crashed when it asked for the ACCESS_FINE_LOCATION permission. I didn't really need it so I deleted it from the code.

[chavarinbonbyn]

This fails on a Huawei phone. In my other phones works just fine. This applies for the laptop as well. What could be the issue ?
