Kivy : Error weakly-referenced object (in a clock function) no longer exists

Question

So here is my error code I think there\'s something hard in this error, i looked on forums but couldn\'t find out.

And ... i have the error on my phone

Answer 1

What I usually do to keep a reference to e.g. my_object is to add my_object: my_object.__self__ line in the kv part of my root rule.

Since you haven't provide any code, I can't be more specific...
