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

savedInstanceState will be null if the app is not already loaded in memory. If you want to detect whether the app has run for the very first time, you have to apply different technique, such as using sharedPrefs / DB to store a property for the first run.

i.e. Check sharedPrefs for property "firstRun"

if exists, then it is not a first run

else it is the first run

set the firstRun property to true
