These are my blocks. I have searched for similar issues and it says install apk to fix the issues. But im still not able to fix the issue. The issue is its not able to function well as when we put the timing for the sleep tracker, it will automatically set to 12.00am instead of the timing stated.
In your AfterTimeSet event you set the alarm time to 00:00... so each time you set a new time, you set again the alarm to 00:00... is this what you want? therefore each time you get the message, that the alarm already has been set... hope that helps...
