How do I implement MVVM in my Android app?

To implement MVVM in your Android app, start by creating your Model, View, and ViewModel classes. The Model handles data, the View displays it, and the ViewModel acts as a bridge.

What libraries should I use for MVVM in Android?

You can use libraries like LiveData, ViewModel, and Data Binding from Android Jetpack to simplify your MVVM implementation.

Can you give me a simple code example?

Sure! Here's a basic example:

class MyViewModel : ViewModel() {
    val data: LiveData<String> = MutableLiveData("Hello, MVVM!")
}

class MyActivity : AppCompatActivity() {
    private lateinit var viewModel: MyViewModel

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        viewModel = ViewModelProvider(this).get(MyViewModel::class.java)
        viewModel.data.observe(this, Observer { value ->
            // Update UI
        })
    }
}

What are the benefits of using MVVM?

MVVM promotes separation of concerns, making your code more modular and testable. It also enhances UI responsiveness by using data binding.
