PythonActivityUtil helper for unpacking data by AndreMiras · Pull Request #2189 · kivy/python-for-android

AndreMiras · 2020-05-10T21:59:50Z

This helper class shares code to be reused between the PythonActivity
classes of the different bootstraps.
Also adds few minor adjustments to existing classes.

I tested the artifacts for arm64-v8a and armeabi-v7a and both apps crashes before unpacking files:

Thank you for checking @opacam so I could eventually break it 🎉 😄
From my local tests it was working perfect with the tests apps, but maybe then I haven't cleaned things up properly before building again.
I'll take a look later. Thanks again for the heads up

Incredible I've tested both artifacts and they are working on my device 🤔

I'll try to understand what's going on by looking at your stacktrace.

opacam · 2020-05-11T19:39:51Z

I will try again, it could be a transfer issue with my phone

AndreMiras · 2020-05-11T19:47:14Z

That seems very unlikely to be a transfer issue to me. The stacktrace you shared is close to things I've touched so it could really be a regression on certain device. If you can reproduce on this PR, could you also check if current develop testapps are also crashing or if it's just this pull request?
In the meantime I'll try to see if I can reproduce with other devices. I may have idea how to fix, but first I want to be able to reproduce

opacam · 2020-05-11T19:50:26Z

Yea, I will try with latest artifact of develop branch...

BTW, the same error:

For the record: I tested with Android 10 device

Develop is working, tested arm64-v8a artifact

AndreMiras · 2020-05-11T20:06:27Z

OK thank you good to know it's only this PR and develop is still OK.
I'll try to find a device where to reproduce, there's no rush to merge this.
Thanks for the help 🍻

opacam · 2020-05-11T20:18:29Z

No problem, ping me when you need me 😉
Btw, I think that is a very good refactoring, thanks!!

AndreMiras · 2020-05-11T20:20:39Z

Great I could reproduce on another device!
Will try to work on the fix now

AndreMiras · 2020-05-11T21:10:03Z

Got a working fix I think, but linting errors started popping.
So let's first merge #2191 and rebase

This helper class shares code to be reused between the `PythonActivity` classes of the different bootstraps. Also adds few minor adjustments to existing classes.

Awesome work!!, thanks!!

Note: tested the latest artifact for arm64-v8a without any issue 😄
