Question

If I initialize some static objects in an activity and then call finish(), do those objects still exist elsewhere in the application? Like say I want to access them later on in a service.

If not, are there any other solutions where I could initialize some static objects one time that other classes will have access to?

Answer 1

Yes, doing that is possible. But for the static objects to continue to exist, there should be at least one Activity/Service in the application to be running. What I normally do for such variables is to create a class to hold static methods and variables. Something like this:

public class Utils
{
    public static String s;
    public static int i;

    public static initStatics()
    {
        s = "";
        i = 0;
    }
}

This you can call from your other Activity/Service like this:

public class CustomService extends Service
{
    @Override
    public void onStart()
    {
        Utils.initStatics();
    }
}

So, these variables will be available as long as your app is running. Hope that helped. Good luck!
