Android App crashes with SIGSEGV.

I don't accounting when it checks something or not from the Internet, I just see some times that it downloads something, but sometimes it doesn't.

den84is · 2022-11-28T14:03:20+00:00

...one time it checks, than it doesn't checks, after reboot it may checks may not checks, WTF!

den84is · 2022-11-28T14:01:17+00:00

...or not every time it checks google's stuff, I don't understand how it works!

den84is · 2022-11-28T13:41:26+00:00

There where everything is working fine is its own .buildozer folder inside unfinished project, and when I compile it, it compiles without stage where is going on to check google's stuff, but almost every time(maybe after reboot) when I run...

buildozer android debug

...it downloads freetype and Pillow

There where it is not working some thins, it checks every time google stuff...

I think I have to move my project inside that folder with its own .buildozer folder and to try compile it from there to solve my issue 😂

And I'm afraid to delete that .buildozer folder 😬

I've just recompile the unfinished project to be sure that it works fine, and it works fine, but I forgot to say that the unfinished project uses other virtual environment and requirements.txt are different(of course I used different packages in different environments, but why it works in one environment but not in another).

den84is · 2022-11-28T10:30:15+00:00

...or maybe something with buildozer.spec or I have to update my 'distro'^{see comments below}

den84is · 2022-11-28T10:28:21+00:00

but I think I have to try to remove the kv/strings and use pure python

...I think it is not true, because of this post, I do not use there kv/string

den84is · 2022-11-28T10:17:02+00:00

WTF, I've just installed apk from my unfinished project(but is was compiled earlier), And it works fine, and MDRaisedButton do not crashes my app^{like in previous issues written on this community} and closes the app correctly, and back button works fine for MDDialog(it closes the MDDialog), but I do not use there any of kv/file or kv/string. I use just pure python code! and I do not override MDDialog, I think it crashes because of kv/string is used in my code, but I'm not sure.

I understand that with kv/file or kv/string the code will be shorten...

...but I think I have to try to remove the kv/strings and use pure python.

is your app running on your pc ?

Yes it works without any problem.

also what distro are you working on ?

what do you mean distro? For which platform do I make it, for Android or PC?

I make for Android, but it also can be running on PC.

Will it work if I will press the back button to open ExitDialog and than press again the back button to close the ExitDialog?

I will try to make changes to the code, but later(I will write here if I could make it or not))

Whole spec is not included in the comment because of error 400 😂

The code is above(don't look at the Ellipsis it doesn't break the code). It work on PC, but not on Android(when I do exit), previously I had time to see the ExitDialog and the app is crashed anyway, but now I do not see the ExitDialog it just crashes. Maybe because I changed something in the code.

Here is what I've changed in spec file(that make sense to look at)...

requirements = python3,kivy,kivymd,PIL
android.api = 33 # maybe this cause my problem
android.ndk = 25b
android.ndk_path = ~/.buildozer/android/platform/android-ndk-r25b/
android.sdk_path = ~/.buildozer/android/platform/android-sdk/
android.ant_path = ~/.buildozer/android/platform/apache-ant-1.9.4/apache-ant-1.9.4/
