5 Design Patterns Every Android Developer Must Know

Common Design Patterns for Android Developer

1. Singleton: This pattern assures that a class has only one instance and offers global access to it.

2. Observer: This pattern creates a one-to-many relationship between objects, so that when one object's state changes, all of its dependents are automatically notified and changed.

3. Factory: The factory pattern provides an interface for creating objects in a superclass while allowing subclasses to customize the type of objects created.

4. Builder: This pattern isolates a complex object's production from its representation, allowing the same construction process to generate multiple representations.

5. Adapter: This pattern enables classes with incompatible interfaces to collaborate by wrapping one class in an adapter that translates calls to the other.

It is important to note that design patterns are not a one-size-fits-all solution and should be used appropriately based on your application's specific needs.
