Hello, sorry if naive question, but I am not sure how to google it.
I wonder if I can share some variable between each launch of app, without saving it to file.
I know how to save to file, and read it. But I need to do some trivial thing:
I want to show some tip for user when he launch the app. But I want that tip to appear only for example first 2 times he launch the app.
Do I need to save it to the file? Or is there any smarter way?
