I have an Android app with a main fragment that you can navigate from using navigation graph. Data is loaded when the main fragment is opened. The problem is when I navigate from it and go back the data is loaded again, because fragment is recreated. How is it possible to load data only once?

You can use ViewModel with the app and make a check if the ViewModel is already created do not load the data again
