What is the application of StrongReference in memory management?

StrongReference in memory management is a regular reference to an object that prevents it from being garbage collected. As long as there is at least one strong reference to an object, the garbage collector will not remove this object from memory.

Example: if you have an object and assign it to a variable, this variable is a strong reference. The object will live as long as this variable exists and refers to the object.

In Android, this is important to not lose necessary objects, but caution is needed to avoid memory leaks, for example, when strong references hold objects longer than necessary.
