In the previous lesson, you have seen that implementing MVP for a Fragment is pretty straightforward and simple, especially if you are using Dependency Injection. But how do we implement a passive RecylerView (or any other adapter views for that matter)? Generally, we create a collection within the adapter to hold the data. But this approach breaks the MVP principle...

Unfortunately, there is no “standard” way to implement MVP for Android apps 😐. There are many variations of MVP and developers adjust this pattern idea to their own style and needs. And since this is my blog, it's my way or highway 👹. My style of MVP implementation is more focused on testability rather than ease of implementation. It...

Maintaining a clean architectural pattern is imperative for project maintenance and ensuring that it is clean, testable, and expandable. In Android domain, the classic Model View Controller pattern is no longer the default choice for developers. More and more developers are shifting their loyalty to Model View Presenter pattern (including me 😝). Watch the two videos about the MVC...

Dagger 2 Dagger 2 is a framework that has been developed to simplify the process of applying dependency injection. Once you have applied Dagger 2 in your project, you will find some classes automatically generated for Dependency Injection in your app. Look at one such snippet of generated code. public final class ContextModule_ProvideUPayServiceFactory implements Factory { private final...

What is Dependency Injection?  First of all the term sounds frightening 😛. When I heard the term first, I thought it must be some very difficult design pattern meant only for very advanced developers. Now I can't imagine writing applications without it. So let's see a nice video about Dependency Injection and then we will discuss it further. Let me...

Getting Started The first step should be to clone the sample app repository and build the application in your own Android Studio. I would also suggest that you should simultaneously code your own app which is very similar to it. Like, for your entry screen you can use Github API and display most popular Android repositories! You will...

What this tutorial expects you to know So let's set out the pre-requisites before we proceed together on this journey. Something like a prenuptial agreement 😛. You should know Java (stuff like OOP, Inheritance, Interface etc.) and should have developed some Android app, even if as a hobby or learning exercise. In summary, you should have at least...
