You need to specify the version number for your APK in the main.py file. It should take the format of:

__version__ = '0.0.1'

You could also specify the version in your buildozer.spec file by commenting out lines 29 and 29 and uncommenting line 32.

Thanks for your help, i did generate the apk but when i run it on my device, there is a loading and after it go out, i can't open the application. but the application has been correctly installed on device. thans in advance for your help

You need to get the logs from the device to have any idea why it is crashing.

okey but how can i get it? i remind you that i'm newbie so will you help me step by step please how can i fix it. I installed an android emulator such as Bluestacks but it's the same when i ran the app by clicking on the app's logo, i got a app's loading and after it all came back on the menu of device. it seem that  the apk is empty or bad. thanks in advance for your help.

use this

buildozer android debug deploy run logcat

that will launch your app and start showing you the device logs at the terminal in real time.

also if your not using buildozer you can run.

adb logcat

at a terminal to start logging for your device.
