What is the main execution flow of the application?

The main execution thread of the application is the Main thread, also known as the UI thread. It is responsible for:

• Handling user interface events (clicks, swipes, etc.).
• Updating the user interface (drawing Activity, View).
• Executing code that interacts with UI elements.

All operations that could block the UI thread (such as network requests, long computations, database operations) should be performed in separate threads to avoid ANR (Application Not Responding).
