The snippet I showed you is a non anonymous Handler class you can use without leaking your Activity.
The host property is stored in a WeakReference using the delegate I shared earlier here: https://gist.github.com/LouisCAD/7ce3a30cb88c27858b12d5f26c118b0b
You can then create an instance of this Handler in your Activity passing the Activity itself, or an anonymous class of the Activity as the Host, or any object tied to the Activity lifecycle (can also be instantiated there), without risking a memory leak since you're using a WeakReference
