Setting Singleton property value in Firebase Listener

Question

I\'m currently testing out Firebase along with a Singleton model I plan to use to access during the lifecycle of the whole app. I\'m now stuck with something that seems real

Answer 1

You have to initialize your Singleton when the class is loaded. Put this on your code:

private static BookSingleton  model = new BookSingleton();

private BookSingleton() {
}

public static BookSingleton getModel() {     return model == null ? new BookSingleton() : model;
}
