// Example of using ViewModel and LiveData in Android
public class MyViewModel extends ViewModel {
private MutableLiveData data;
public LiveData getData() {
if (data == null) {
data = new MutableLiveData<>();
loadData();
}
return data;
}
private void loadData() {
// Load data asynchronously (e.g., from a database or network)
data.setValue("Hello, World!");
}
}
// In your Activity or Fragment
