Unity: чтение json с android

Спустя несколько дней, как я начал сходить с ума по этой проблеме, нашлось решение. Все дело в цикле while (!reader.isDone) { }. Видимо, он криво выполнялся и вел к тому, что файл не читался. Прилагаю свой рабочий код:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using System.IO;
public class LocalizationManager : MonoBehaviour {
public static LocalizationManager instance;
private Dictionary<string, string> localizedText;
private bool isReady = false;
private string missingTextString = "Localized Text not found";
// Use this for initialization
void Awake () {
    if (instance == null)
    {
        instance = this;
    }
    else if (instance != this)
    {
        Destroy(gameObject);
    }
    DontDestroyOnLoad(gameObject);
}
public void LoadLocalizedText(string fileName)
{
    localizedText = new Dictionary<string, string>();

    string filePath = Path.Combine(Application.streamingAssetsPath, "Languages/" + fileName + ".json");
    Debug.Log(filePath);
    if (File.Exists(filePath))
    {
        string dataAsJson = File.ReadAllText(filePath);
        LocalizationData loadedData = JsonUtility.FromJson<LocalizationData>(dataAsJson);
        Debug.Log("Translate is done on Editor");

        for (int i = 0; i < loadedData.items.Length; i++)
        {
            localizedText.Add(loadedData.items[i].key, loadedData.items[i].value);
        }
        Debug.Log("Data loaded, dictionary contains: " + localizedText.Count + " entries");
    }
    else
    {
        Debug.LogError("Can not find file!");
    }
    isReady = true;
}

IEnumerator LoadLocalizedTextOnAndroid(string fileName)
{
    localizedText = new Dictionary<string, string>();
    string filePath = Path.Combine(Application.streamingAssetsPath, fileName + ".json");
    WWW reader = new WWW(filePath);
    yield return reader;
    Debug.LogWarning(filePath);
    if (reader.error != null)
    {
        Debug.LogWarning(reader.error);
        yield break;
    } 
    string dataAsJson = reader.text;
    LocalizationData loadedData = JsonUtility.FromJson<LocalizationData>(dataAsJson);
    Debug.Log("Translate is done on Android");
    for (int i = 0; i < loadedData.items.Length; i++)
    {
        localizedText.Add(loadedData.items[i].key, loadedData.items[i].value);
        Debug.Log("KEYS:" + loadedData.items[i].key);
    }
    isReady = true;
}

public void SetLanguage(string fileName)
{
    if (Application.platform == RuntimePlatform.WindowsEditor)
        LoadLocalizedText(fileName);
    else if (Application.platform == RuntimePlatform.OSXEditor)
        LoadLocalizedText(fileName);
    else if (Application.platform == RuntimePlatform.Android)
        StartCoroutine("LoadLocalizedTextOnAndroid", fileName);
}

public string GetLocalizedValue(string key)
{
    string result = missingTextString;
    if (localizedText.ContainsKey(key))
    {
        result = localizedText[key];
    }
    return result;
}
public bool GetIsReady()
{
    return isReady;
}
}
