What is the difference between <uses-permission> and <permission> tags in Android manifest?

Automatic memory cleanup (Garbage Collection) is important in the following cases:

• When developing applications with dynamic allocation of many objects to avoid memory leaks.
• In multithreaded applications where manual memory management is complicated.
• When working with long-living services where accumulation of unused objects can lead to performance degradation.

Considering the garbage collector's work helps optimize memory usage and improve application stability.
