Android’s memory management system is responsible for allocating and deallocating memory resources for apps running on the device. It uses a combination of techniques such as garbage collection and automatic memory management to reclaim memory that is no longer in use. Android also employs a process called low memory killer that terminates background processes when the system is low on memory to prioritize foreground app performance.

Android’s memory management system handles the allocation and deallocation of memory resources for apps on the device. It uses techniques like garbage collection, which automatically frees up memory that apps are no longer using.
When an app is running, it uses memory to store data and perform tasks. However, when the app no longer needs certain data or when it closes, Android’s memory management system steps in to reclaim that memory and make it available for other apps or system processes.
Additionally, when the device’s memory is running low, Android’s memory management system employs a process called “low memory killer.” This process identifies background processes that are using up memory but are not currently in use by the user. It then terminates these processes to free up memory and prioritize the performance of the app that the user is actively using.
In simple terms, Android’s memory management system ensures that memory resources are used efficiently. It automatically cleans up unused memory and stops unnecessary background processes when the device is running low on memory, helping to maintain smooth app performance.
