Question

所以在我的应用程序中，我通过一个名为datacontroller的游戏对象来完成我的三个场景。持久场景是一个空场景，菜单屏幕场景，然后是游戏场景。我的应用程序在我的计算机和编辑器模式下完美运行，但当我下载apk到我的Android平板电脑它不再有效！我读过这可能与我的对象代码有关，但我不认为我写的只能在编辑器中运行。

enter code here
using UnityEngine;
using UnityEngine.SceneManagement;
using System.Collections;
using System.IO;                                                             // The System.IO namespace contains functions related to loading and saving 
files

public class DataController : MonoBehaviour
{
    private RoundData[] allRoundData;
    private PlayerProgress playerProgress;

private string gameDataFileName = "data.json";

void Start()
{
    DontDestroyOnLoad(gameObject);

    LoadGameData();

    LoadPlayerProgress();

    SceneManager.LoadScene("MenuScreen");
}

public RoundData GetCurrentRoundData()
{
    // If we wanted to return different rounds, we could do that here
    // We could store an int representing the current round index in PlayerProgress

    return allRoundData[0];
}

public void SubmitNewPlayerScore(int newScore)
{
    // If newScore is greater than playerProgress.highestScore, update playerProgress with the new value and call SavePlayerProgress()
    if (newScore > playerProgress.highestScore)
    {
        playerProgress.highestScore = newScore;
        SavePlayerProgress();
    }
}

public int GetHighestPlayerScore()
{
    return playerProgress.highestScore;
}

private void LoadGameData()
{
    // Path.Combine combines strings into a file path
    // Application.StreamingAssets points to Assets/StreamingAssets in the Editor, and the StreamingAssets folder in a build
    string filePath = Path.Combine(Application.streamingAssetsPath, gameDataFileName);

    if (File.Exists(filePath))
    {
        // Read the json from the file into a string
        string dataAsJson = File.ReadAllText(filePath);
        // Pass the json to JsonUtility, and tell it to create a GameData object from it
        GameData loadedData = JsonUtility.FromJson<GameData>(dataAsJson);

        // Retrieve the allRoundData property of loadedData
        allRoundData = loadedData.allRoundData;
    }
    else
    {
        Debug.LogError("Cannot load game data!");
    }
}

// This function could be extended easily to handle any additional data we wanted to store in our PlayerProgress object
private void LoadPlayerProgress()
{
    // Create a new PlayerProgress object
    playerProgress = new PlayerProgress();

    // If PlayerPrefs contains a key called "highestScore", set the value of playerProgress.highestScore using the value associated with that key
    if (PlayerPrefs.HasKey("highestScore"))
    {
        playerProgress.highestScore = PlayerPrefs.GetInt("highestScore");
    }
}

// This function could be extended easily to handle any additional data we wanted to store in our PlayerProgress object
private void SavePlayerProgress()
{
    // Save the value playerProgress.highestScore to PlayerPrefs, with a key of "highestScore"
    PlayerPrefs.SetInt("highestScore", playerProgress.highestScore);
}

}

我开始自己通过统一教程，所以我不是专家。：）

但我会尝试的是第一件事。 using System.IO;不确定这是否可以在android上获取文件，因为android具有不同的文件结构。因此，我首先删除它并对文件路径进行硬编码或使用System.IO类注释掉代码，然后在统一中重新编译apk并检查它是否有效。我也看过这篇文章：http://answers.unity3d.com/questions/1023391/systemio-dont-work-on-android.html

如果这不起作用我会评论功能并编译apk并检查它是否工作，如果它没有评论更多的代码，直到你找到导致它在Android上的错误的行或代码。这种方法需要很长时间才能排除故障或导致代码导致问题，但对我来说这已经成功了。

我猜是因为它正在你的pc上工作它的类或其引用的东西在android中不可用。

如果您弄清楚代码的哪一部分，请分享您的发现。因为我也想知道阻止我这样做。：）

避免在Android上使用System.IO，一般在Unity上使用。

请改为使用“资源”，只需执行以下步骤：

创建名为“资源”的文件夹
在其上移动json文件并重命名为.txt
使用此代码获取字符串：

var file = Resources.Load("filename_here") as TextAsset;
Debug.Log(file.text)

统一android游戏对象无法正常工作
