5 Design Patterns Every Android Developer Must Know

Common Design Patterns for Android Developer

1. Singleton: This pattern ensures that a class has only one instance, and provides a global point of access to it.

2. Observer: This pattern defines a one-to-many dependency between objects, such that when one object changes state, all of its dependents are notified and updated automatically.

3. Factory: This pattern provides an interface for creating objects in a superclass, but allows subclasses to alter the type of objects that will be created.

4. Builder: This pattern separates the construction of a complex object from its representation, so that the same construction process can create different representations.

5. Adapter: This pattern allows classes with incompatible interfaces to work together by wrapping one class with an adapter that translates calls to the other class.

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