To handle memory leaks in Android applications, first identify the leaks using tools like LeakCanary and Android Profiler. LeakCanary is a library that detects leaks by monitoring heap dumps and notifying developers when an object is retained longer than necessary. Android Profiler provides real-time data on memory usage, allowing you to pinpoint problematic areas.
Once identified, fix memory leaks by:
1. Using WeakReferences for non-critical objects.
2. Unregistering listeners or callbacks during onPause() or onStop().
3. Avoiding static references to Context or View objects.
4. Properly managing threads and AsyncTask instances.
5. Releasing resources such as Bitmaps, files, or network connections when no longer needed.
6. Implementing onDestroy() method to clean up resources and release memory.
Optimize memory usage further by employing techniques like caching, lazy loading, and recycling views with RecyclerView. Regularly monitor your application’s performance using the aforementioned tools to ensure optimal memory management.
