I'm in the process of completely redesigning my Android app. Before, EVERYTHING was in the same class. So I tried to redraw everything so that the code is clearer apart Admob than the doc advice to put in the Main thread, I separate the different part of my code in class. So I used two technique: I created a songleton that contains variables that I want to have access to constantly,and I call my classes via weak reference.
Here is what it looks like: For example, the UIManager class that needs to update the game's IU have a weak reference looks like this:
private static SoftReference<UIManager> ManageUI;
static{ManageUI= new SoftReference<>(null);}
static UIManager get()
{
if(ManageUI.get()==null)
{
ManageUI= new SoftReference<>(new UIManager());
}
return ManageUI.get();
}
GameManager Manager=GameManager.getInstance();
to be able to use the findviewbyid for example I place in method argument the main class that is the mainthread
the singleton that contains all my variables that I want to have permanent access to looks like this:
private GameManager()
{}
/** Holder */
private static class Manager
{
/** Instance unique non préinitialisée */
private final static GameManager instance = new GameManager();
}
/** Point d'accès pour l'instance unique du singleton */
public static GameManager getInstance()
{
return Manager.instance;
}
To separate all in different class, I pass argument to my method so I can call au stuff belong to Activity like that: (My main class is called GamePlay)
void OpenGlobalScene(GamePlay activity)
{
Manager.OnTitle=false;
if (!checkLayout(activity,R.id.globalscene)) {
LayoutInflater(activity,9, true);
LinearLayout GamePlan = (LinearLayout) activity.findViewById(R.id.globalscene);
GamePlan.setAlpha(Manager.AlphaBord);
}
}
For now, I have not noticed any problems except a few slownesses on old android phone 4.4.2. Also compared to my old code were EVERYTHING was in the same class, it's much easier to change pieces of code (going to the inapp billing V3 was simpler since everything was in one class that I call like the others with weak referencre)
My questions are: -What are the problems that such a structure might pose? I had also chosen that structure to not load or leave in memory things that are not useful -How are chance that Android will erase from memory an action in progress called with weak reference? -As you can see I pass the activity has argument to the method, sometimes I pass it from a method to another. Is that fact can cause some trouble?
Thank you for your help.
