My GeofenceTransitionsIntentService does not send any notifications when a geocenter transition occurs

Question

I am trying to implement the function of adding and monitoring geopotentials, and I thought that this tutorial is the best one to start with.

I did everything as they described, and it works, but not in the way I would like. I noticed that geofence transistors are not being tracked, what I really want to say is that when I enter geofence, nothing happens, but when I run the application inside the geofence, I get some response. I also noticed that none of the methods from my GeofenceTransitionsIntentService are executed, which actually means that geospatial transition data will never be broadcast to MainActivity.

Honestly, this is the first time I'm trying to implement such a function, so I really don't know what could be causing this problem. If you have an idea, answer, I will be grateful.

This is what I have done so far.

My GeofenceTransitionsIntentService.java
