I’m developing an android game, and just added a main menu. This is a separate activity – so when someone clicks the ‘new game’ button on the menu, it opens a new intent to the game activity.

My problem is if the user hits ‘back’, it closes the game and returns to the main menu. When I hit ‘New Game’ again, it crashes.

I think it is attempting to make a second version of the game, and running out of memory. Should I be trying to hold a copy of the game activity in the menu, then reopen it if they hit ‘New Game’ again? Or is there an easier way to do this?

My “new game” button listener does the following: (IslandGame is my main game class – the bundle is just to tell it whether to start a new game or load a previous game, and which level to start in)

ButtonNewGame.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {                 
            Bundle bundle = new Bundle();
            bundle.putString("RESTORE", "NEW"); //in the restore key, say we want a new game
            bundle.putInt("CAMPAIGN", 1); //start in campaign #1

            Intent intent = new Intent(Intent.ACTION_RUN);
            intent.putExtras(bundle);
            intent.setClassName(thisActivity, IslandGame.class.getName());
            startActivity(intent);
        }         
    });

The logcat is:

    I think it is attempting to make a second version of the game, and running out of memory.

    You are absolutely correct. If you properly finished the game activity, then it should be trying to create a second version because the first version should be gone.

    Should I be trying to hold a copy of the game activity in the menu, then reopen it if they hit ‘New Game’ again?

    In general, this is considered a horribly bad practice for a number of reasons. The most important of these is a memory leak due to contexts.

    Or is there an easier way to do this?

    You may define the game activity as a singleTask or singleInstance. An issue with this (at the moment) is that it is not a solution to fix memory bugs. SingleTasks are programmed differently than multiple instance applications and there are other considerations. Since your issue lies in the fact that you have memory being used in the first place, before going this route, I would definitely review the following:

    1. Make sure all resources are released. Of particular concern here is any static reference to a View. If you have them, clean them up.

    2. Make sure ALL bitmaps are recycled. Sometimes when resizing bitmaps, the original is left behind. Often a silly oversight. Just take a look. 🙂

    3. If you are accessing files, make sure they are closed. Almost never the problem, but always worth a try.

    4. Add a System.gc() call after your game activity is finished. This really can help after a major release of resources. Unfortunately, it is not guaranteed to. In your case, it might be best in the onResume() of your Main Menu.

    Once you have exhausted all of those, then the singleTask route is simply choice of implementation.

    Hope this helps,
