com.google.firebase.database.DatabaseException: Calls to setPersistenceEnabled() must be made before any other usage of FirebaseDatabase instance

Question

I am having a problem when I try to setPersistence in fIREBASE,can someone please explain on how to go about it,

protected void onCreate(Bundle savedInstance         


        

Answer 1

You could try checking if there are any initialized firebase apps before calling setPersistenceEnabled.

if (FirebaseApp.getApps(this).size() == 0)
    FirebaseDatabase.getInstance().setPersistenceEnabled(true);
