Weak handler
Memory-safe Android Handler implementation using WeakReferences to prevent memory leaks from delayed messages and runnables.
What is Weak handler?
Android Weak Handler is a memory-safe implementation of Android's standard Handler class that prevents memory leaks by using WeakReferences for posted messages and runnables. It solves the problem where anonymous Runnables or Messages create hard references that keep large objects like Activities or Fragments in memory longer than necessary, especially when using delayed posts with large timeouts.
Android developers working with Handlers, particularly those building Activities, Fragments, or other UI components that use delayed operations and want to prevent memory leaks.
Developers choose Android Weak Handler because it provides a drop-in replacement for the standard Handler that automatically prevents common memory leaks without requiring code changes, making memory management safer by default while maintaining full API compatibility.
