I the last i've been creating some sort of a "contacts" app. In the main activity i have created a listview that syncronises itself with an ArrayList of strings(names). To add names to the the listview i created another activity. I have managed to get the two activities to talk to each other(send the name(the string) to the "list" activity), but i am struggeling to find a way to save the the ArrayList.
The problem is that every time the "list" activity is leaved and then resumed all the old content disappears.
So, i guess i need a good way to save an ArrayList?
