A badly written code is a NIGHTMARE (when needed to maintain). For any developer there is nothing better than having a clean, structured code. And if you want to achieve this, you must follow a design pattern for your projects. So this Android MVVM Tutorial is for all the people out there who learned the basics of android development and now want to learn something advanced. Because if you are seeking a JOB then knowing only the basics are not enough. You should know some design patterns.
What is MVVM?
MVVM stands for Model View ViewModel and it is a design pattern that is used to build softwares. But here our focus is only about Android App Development. MVVM helps us to separate the Business Logic of our Application from the Views or UI. And doing this thing is very important in case of any kind of software or app development.
Model : This is responsible for handling the data in the application. Model cannot directly interact with Views, but it interacts with ViewModels and then Views with the help of observables. (Sounds confusing right? Don’t worry in the course we will cover every step in detail).
View: This is the User Interface of our Application. It should not contain any application logic.
ViewModel: It is basically a link between Model and View.
MVVM in Android
When we want to use MVVM in Android, we use this architecture.
One more thing is involved here and that is the Repository. So repository is responsible for handling the data. Repository may use multiple data sources according to the need, it may fetch data from a Remote Source or from the local storage.
Advantages of using MVVM
Now let’s talk about what are the advantages of using MVVM in your android project.
- If you use MVVM it will help you structuring your code in a nice way so that it is easy to understand for a new developer.
- Using MVVM makes your project maintainable as everything is well organized and making changes are very easy.
- Testability is easy with MVVM because all modules are independent and testable.
- MVVM enhances the re-usability of the code.
