What are the main difficulties that can arise from improper implementation of structured concurrency?

Incorrect implementation of structured concurrency in Android can lead to the following issues:

• Memory and resource leaks: if coroutines or tasks are not properly canceled, they may continue running in the background, consuming resources.
• Difficulty canceling tasks: lack of proper lifecycle management of tasks results in tasks continuing to execute even when they are no longer needed.
• Unpredictable UI behavior: if asynchronous operations are not synchronized with component lifecycles (Activity, Fragment), it can lead to errors or crashes.
• Debugging difficulties: without a clear structure, it is hard to understand which tasks are active and how they interact.

Proper structured concurrency helps avoid these problems by providing a hierarchy of tasks and their correct completion.
