Probably a stupid question, but what do I have to change to make this code work:

package com.hobogames.WizardsDuel;

import com.badlogic.gdx.Gdx;
import com.badlogic.gdx.Preferences;

public class GameData {
    public static String version = "1.0.0";

    public static String data[] = {"version"};
    public static final int VERSION = 0;

    public static Preferences prefs = Gdx.app.getPreferences("WizWars");
    public static boolean played = (!prefs.get().isEmpty());

    public static String getString(int key){
        return prefs.getString(data[key]);
    }

    public static void storePrefs(){
        prefs.putString(getString(VERSION),version);
        prefs.flush();
    }
}

The part in particular that isn't working is that "played" is false every time on an android device. On desktop it's true after the first play.

我怀疑你被staticAndroid 和桌面上的行为不同的状态所困扰。当您在 Android 上退出应用程序时，您确定 VM 会退出吗？如果你在 Android 上快速重启你的应用，系统会为新的 Activity 重用同一个 Dalvik VM。由于static boolean已经初始化，因此不会重新运行初始化。如果你删除了，static所以这些东西在创建时会重新运行GameData（可能它的实例没有存储在静态变量中）你应该走得更远。
