How does LeakCanary detect memory leaks in an application?

LeakCanary detects memory leaks in Android applications by tracking objects that should be released but remain in memory after the corresponding Activity or Fragment has been destroyed.

How it works:

1. LeakCanary automatically monitors the lifecycle of application components.
2. After a component is destroyed, it checks whether there are still references to objects associated with that component.
3. If such objects have not been garbage collected, LeakCanary considers this a leak.
4. LeakCanary then generates a report with information about the chain of references preventing the object from being released.

This helps developers quickly identify and fix memory leaks.
