A badly written code is a Night Mare (When needed to be maintained). There is nothing better for any developer than having clean, structured code. And if you want to achieve this, then you should follow a design pattern for your projects. So this Android MVVM tutorial It is for everyone who has learned the basics of Android development and now wants to learn something advanced. Because if you are asking for JOB then it is not enough to know only the basics. You should know some design patterns.
What is MVVM?
MVVM means MOdell View ViewMOdell and this is a design pattern used to create softwares. But here our focus is only on Android App Development. MVVM helps us to separate the business logic of our application from the view or UI. And in case of development of any kind of software or app it is very important to do this work.
Sample: It is responsible for handling data in the application. The model cannot interact directly with the view, but it interacts with the ViewModels and then the view with the help of observatories. (Right confusing voice! Do not worry in the course we will explain each step in detail).
Opinion: This is the user interface of our application. It should not contain any application logic.
Viewmodel: This is basically the link between the model and the view.
MVVM in Android
When we want to use MVVM in Android, we use this architecture.
One more thing is included here and that is Repository. Therefore the repository is responsible for handling the data. The repository can use multiple data sources as per requirement, it can receive data from remote source or from local storage.
Benefits of using MVVM
Now, let’s talk about the advantages of using MVVM in your Android project.
- If you use MVVM it will help to structure your code in a good way so that it is easier for a new developer to understand.
- Using MVVM makes your project maintainable because everything is well organized and it is very easy to make changes.
- Testing capability is easy with MVVM because all modules are independent and testable.
- MVVM increases reusability of code.
