The repository will perform email changing operation with DB, Firebase or API, cache results in local memory and distribute new info to subscribers through RxJava subjects. It also maps elements to the understandable by UI layer type, by reducing amount of outer layer dependencies or adding fields that might be needed to display content. We will follow the dependency rule on this well-known picture to have an application with interchangeable parts.

Dagger2 is used to avoid detail-complicated boilerplate code of connecting architecture elements one to another. Dagger2 is a great library that allows you to everything you need where you need it and handle the lifecycle of created objects.

Dagger2Ī fast dependency injector for Android and Java. Seriously, you should check it out if you’re still not familiar with RxJava. But in my opinion, the main purpose of RxJava is to have universal structures for data flow in an application. RX operators that RXJava provides easy to use stuff for working with data streams and threads. Looking for extra hands? Hire Dedicated Android Developers at Uptech. Functional part of Kotlin will reduce side effects of your code and make it easier to test and understand. This will allow you to think less about implementation details and more about the whole app structure. Kotlin features extremely simplify android development not just by allowing you to use smaller constructions of language, but maintaining semantically right functions in your app. On the first sight you may consider Clean architecture as a bunch of abstract ideas without ‘real code’ power, but in this article I’ll try to show you how these may be implemented on the Android side.Īt first let’s have a quick intro to the project structure: I will be using Views and Presenters to display the UI part of the application and Kotlin+RXJava2+Dagger2 to implement Clean Architecture principles in the work with networkdbcacheetc. Clean Application is extremely maintainable, because of interchangeable implementations it would be easy for you to change every aspect of your app: from UI and simple data processing to DB and API frameworks. By implementing the Clean in your project you’ll have decoupled, testable parts for data storing, processing and presenting. The thing I want to describe in this article is application architecture in Clean Architecture way.

We should talk about rv_item_list.Even though we are living in the Agile world with a bunch of available Time and Energy management techniques that are easy to implement in your life, there are still a few things in software development that may increase your productivity and improve general quality of your code. In the constructor you assign an instance of your adapter to this property (note you don’t need to use new in Kotlin) and assign two things to rv_item_list - a LayoutManager (which is used for positioning), and an Adapter (which we’ve just created).

So here you’ve defined the adapter as a lateinit variable - lateinit is telling Kotlin that you want to initialize this at some stage after creation, not the default in Kotlin classes - normally you have to initialize things immediately.

For example, often you’ll see curly brackets used as function parameters:īuildscript It resembles other languages you may have seen but some things look off, often because it is so concise!ĭon’t panic - because it is so extensible there are many ways to write the same code, and many shortcuts that aren’t available in other languages. Here is the complete code if you rather go straight to the end.īefore we start, let’s talk a bit about Kotlin. If you don’t have any Android experience you should be able to follow along but you might have to Google a few things here and there. I’m going to assume you have some Java experience and have at least played around with creating an Android app. Spring Boot is a great way to create a robust REST API with a minimal amount of code. In this tutorial, you’ll use Spring Boot for the API that powers your Android (+ Kotlin) mobile app. The best way to start is by creating a complete app yourself, which you’ll do in this tutorial. Kotlin was recently given official Android support status by Google, but it remains difficult to understand for many developers.
