In Android development, the following design patterns are frequently used:

• MVC (Model-View-Controller) — separation of data, UI, and control logic.
• MVP (Model-View-Presenter) — View and Presenter interact through interfaces, with the Presenter containing the logic.
• MVVM (Model-View-ViewModel) — ViewModel connects the model and view, often using Data Binding.
• Singleton — to create a single instance of a class, for example, a database manager.
• Observer — for implementing event subscriptions, such as LiveData in MVVM.
• Factory — for creating objects without specifying a particular class.

Example of using Singleton for a database manager:

object DatabaseManager {
    fun getConnection(): Connection {
        // returns the connection to the database
    }
}
