What difficulties have you faced during project implementation and how did you overcome them?

When implementing an Android project, I often faced challenges such as managing the lifecycle of activities and fragments, which could lead to memory leaks or incorrect UI updates. To address this, I used Android Jetpack architectural components like ViewModel and LiveData, which help separate logic from UI and manage state correctly.

Another issue was working with asynchronous tasks and network requests. I used libraries like Retrofit and Coroutines, which simplified request handling and error management.

Additionally, there were difficulties in adapting the interface for different screen sizes and densities. I used ConstraintLayout and resources with different qualifiers to ensure proper display on various devices.
