I created a singleton class , but I read that Dagger is better , In may application I changed a objects in my singleton :



public class Singleton {

private static Singleton instance;
public ROOT root;
public ConcurrentHashMap<String, List<LoadingRow>> expandableListDetail = new ConcurrentHashMap<>();
public ArrayList<RowEntity> rowEntities = new ArrayList<>();
public volatile ArrayList<RowEntity> rowEntityArrayList = new ArrayList<>();


private Singleton() {
// Constructor hidden because this is a singleton
}

public static void initInstance() {
if (instance == null) {
// Create the instance
instance = new Singleton();
}
}

public static Singleton getInstance() {
return instance;
}

}


And Now I don not know if I can use a dagger to do this , in singleton I have a list which I use into an Adapter and a class ROOT which I have another objects. And I have a question how I can use dagger in my case , I changed a value in root into rowEntities

  • Why do you use a Singleton to store a list of objects?

  • Off-topic: who tells you you need to use a Singleton? It seems like your application is an architectural mess and adding Dagger won't solve your issue. Dagger won't make your application safer.

  • @ZUNJAE in my service I update this list , in 5 activities I work at this objects , I use a singleton to get this objects and update

  • Why not save those data to disk and only retrieve it when needed?
