kamenchunathan / kivy-android-alarm-manager-example Goto Github PK

First of all thank you so much for your effort to implement android AlarmManager to Kivy. This is the only real example you can find on internet. Unfortunately i know nothing about java. I just need to wake up my app's service every hour through alarm manager when my app is not running because the service is always being killed by android system after a while even i tried sticky service. I just don't know how to trigger it every hour with this example. Is it possible? how? Thanks in advance.

Thank you very the very helpful example..
Android version is 8.0.0
I faced an issue. The notification works fine if the app is on. However, if the app is closed, I get the below error:
