What approaches exist for efficient memory allocation and deallocation in software systems?

In Android, the following approaches are used for efficient memory allocation and release:

• Using the garbage collector, which automatically frees unused objects.
• Avoiding memory leaks, for example, by properly managing contexts (not holding references to Activity or Context longer than their lifecycle).
• Using weak references (WeakReference) for objects that can be removed when necessary.
• Optimizing resource usage, for example, caching images with libraries (Glide, Picasso) and releasing resources in a timely manner.
• Profiling memory with Android Studio tools (Memory Profiler) to identify and fix leaks.

These approaches help keep the application responsive and prevent excessive memory consumption.
