Introduction to app architecture

So far, we have learned how to create apps and designed beautiful UIs with Material 3 and Jetpack Compose. We haven’t yet started adopting any architecture for our apps. In this section, we will look at some of the app architectures that we can use to build our apps. We will also look at some of the best practices that we can follow when building our apps. First, let’s see some of the benefits of using an app architecture:

• Separation of concerns: Using an architecture allows us to separate our code into different layers. Each layer only does one thing. This makes it easy to separate and group our code into different layers. Each layer has its responsibility. This prevents things from being mixed up and makes it easier to maintain our code.
• Easy testing: Using an architecture makes it easy to test our code. We can easily test each layer of our code in isolation since things are not tightly coupled.
• Easy to maintain: Using...
