Detect First Run

Question

I am trying to detect if my app has been run before, by using this code:

(This is in my default Android activity)

@Override
public void onCreate(Bund         


        

Answer 1

The fact is that savedInstanceState holds persistent data across activities. As such if you restart the app, savedInstanceState will be null across runs. You should either use a Preference or some data base entry to keep track of your first run. I myself use a SharedPreference for this purpose.
