Android Firebase - setPersistenceEnabled(true) crashing the app

Question

So I was just trying out Firebase to update Toolbar label of activities from realtime database. I am getting the following error:

12-21 00:25:19.890 10295-10295/

You can use a Model class and use Method inside it such as the one mentioned below.

public class DatabaseUtility {

    private static FirebaseDatabase database;

    public static FirebaseDatabase getDatabase(){
        if(database==null){
            database=FirebaseDatabase.getInstance();
            database.setPersistenceEnabled(true);
        }
        return database;
    }
}

This will return database instance and you can use database.getReference(); method to get Root reference. This will also save some time if the database object is already present.
