### Your question

our Android application initiates background location updates upon user login. However, upon user logout, it's essential to gracefully stop the background service responsible for location updates and unregister all associated listeners to optimize resource usage and ensure proper application behavior.

**So How can we stop background service and dispose all listeners ( stream) in case of user logout or we want to stop listning the location on simple button click**
