【问题描述】：

我的游戏在 Unity 中运行良好，但是当我导出 apk tp android Mobile 2nd Scene 时无法正确加载并且无法运行。

请看图。这是第二个场景，未正确加载，运行按钮无法正常工作，在统一播放模式下运行良好。

【参考方案1】：

这个问题太模糊了，不过，我想到了一些事情： 1. 您是否使用过时版本的 Android SDK 进行测试，然后在手机上运行更新的 Android 版本？

情况是否相反？

您的设备是否有足够的处理能力和 GPU 能力来运行相关场景？

如果您发布一些日志和/或图片会很有帮助。

【讨论】：

您好，感谢您的帮助，请查看我在上面发布的场景 1 和场景 2 代码的代码。期待。谢谢

【参考方案2】：

由于缺乏信息，我只能建议您至少创建仅包含第二个场景（您无法加载的场景）的构建并查看结果。

请填写其他信息（场景加载代码、您的第一个场景层次结构作为屏幕截图等），以便其他人可以更好地帮助您。

同样的问题。

我坚持使用 Endless Runner 代码，它是资产商店中的示例代码。 (https://assetstore.unity.com/packages/essentials/tutorial-projects/endless-runner-sample-game-87901)

我发现 ThemeDatabase.loaded 和 CharacterDatabase.loaded 在 Unity 中都是 true，但在 Android 中是 false。

因此，在 Android 中，interactable 将是错误的。 (bool interactable = ThemeDatabase.loaded && CharacterDatabase.loaded;)

CharacterDatabase.cs 如下。

using UnityEngine;
using UnityEngine.AddressableAssets;
using System.Collections;
using System.Collections.Generic;

/// <summary>
/// This allows us to store a database of all characters currently in the bundles, indexed by name.
/// </summary>
public class CharacterDatabase

    static protected Dictionary<string, Character> m_CharactersDict;

    static public Dictionary<string, Character> dictionary   get  return m_CharactersDict;  

    static protected bool m_Loaded = false;
    static public bool loaded  get  return m_Loaded;  

    static public Character GetCharacter(string type)
    
        Character c;
        if (m_CharactersDict == null || !m_CharactersDict.TryGetValue(type, out c))
            return null;

        return c;
    

    static public IEnumerator LoadDatabase()
    
        if (m_CharactersDict == null)
        
            m_CharactersDict = new Dictionary<string, Character>();

            yield return Addressables.LoadAssetsAsync<GameObject>("characters", op =>
            
                Character c = op.GetComponent<Character>();
                if (c != null)
                
                    m_CharactersDict.Add(c.characterName, c);
                
            );

            m_Loaded = true;

那么，你在那里做了什么，与我的代码没有什么不同？但即使在 Unity 中也没有运行。
