If our app is lagging due to high memory usage, we should start by profiling it using tools like Android Studio Profiler, or Xcode Instruments to pinpoint bottlenecks. We can optimize data structures by replacing HashMap with SparseArray (Android) or using ArrayDeque instead of Stack for better efficiency. Implementing lazy loading and caching will help by loading resources only when needed and using an LRU cache for frequently accessed data. Reducing unnecessary object allocations, tuning garbage collection, and properly managing resources—like closing database cursors and avoiding memory leaks from static Context references—are also key.

I have worked closely with our engineering team to prioritize memory management techniques like implementing lazy loading and optimizing data structures. When explaining these optimizations to stakeholders, I have also learnt to translate memory improvements into tangible user benefits like "40% faster load times on older devices" rather than technical metrics that are difficult to comprehend.

1. Use caching, downscale large images, and load images efficiently 2. Implement Lazy Loading & Pagination 3. Load data in chunks to reduce memory pressure 4. Stream data instead of loading everything at once (Use Memory-Efficient APIs)

You can optimize memory usage by using efficient data structures, implementing lazy loading, reducing memory leaks, and optimizing algorithms to minimize unnecessary object creation.

My number one solution to this issue is optimizing the visuals. You might have to delete some of them and consider hosting it on a dedicated server.
