Android app architectures Standard Android MVP and MVVM
Archi
This repository showcases and compares different architectural patterns that can be used to build Android apps. The exact same sample app is built three times using the following approaches:
Standard Android: traditional approach with layouts, Activities/Fragments and Model.
MVP: Model View Presenter.
MVVM: Model View ViewModel with data binding.
The App
The sample app displays a list of GitHub public repositories for a given username. Tapping on one of them will open a repository details screen, where more information about the repo can be found. This screen also shows information about the owner of the repository.
Libraries used
- AppCompat, CardView and RecyclerView
- Data Binding (only MVVM)
- RxJava & RxAndroid
- Retrofit 2
- Picasso
- Mockito
- Robolectric
Standard Android
The /app
directoy contains the implementation that follows the traditional standard Android approach. This is a couple of layout files, two Activities and the model. The model is exactly the same for the three implementations and it contains: Repository
, User
and a retrofit service (GithubService
).
With this approach, Activities are in charge of calling the GithubService
, processing the data and updating the views. They act kind of like a controller in MVC but with some extra responsibilities that should be part of the view. The problem with this standard architecture is that Activities and Fragments can become quite large and very difficult to tests. Hence why I didn’t write any unit test for this case.
MVP – Model View Presenter
In /app-mvp
you will find the sample app implemented following this pattern. When using mvp, Activities and Fragments become part of the view layer and they delegate most of the work to presenters. Each Activity has a matching presenter that handles accessing the model via theGithubService
. They also notify the Activities when the data is ready to display. Unit testing presenters becomes very easy by mocking the view layer (Activities).
MVVM – Model View ViewModel
This pattern has recently started to gain popularity due to the release of the data binding library. You will find the implementation in /app-mvvm
. In this case, ViewModels retrieve data from the model when requested from the view via data binding. With this pattern, Activities and Fragments become very lightweight. Moreover, writting unit tests becomes easier because the ViewModels are decoupled form the view.

How to create anything in Android
Course Summary
Here is one important question Android developers ask while making apps: “How can I do ________ in Android?”
The following are versions of this question that we came across recently:
- How can I add radio buttons to my app?
- How can I play a sound?
- How can I navigate between multiple screens?
This course is a collection of such questions and their answers.
By the end of this course you will have mastered the ability to implement new Android features by reading a blog or article — this is a critical skill possessed by professional Android developers. As a result, you will also be able to use several User Interface components — like Toggle Buttons, Menus, Grid View and many more — that are central to making functional and delightful Android apps.
