Retreiving Json Data don't Work on Android Devices

So here's my LocalizationManager.cs

Code (CSharp):

1.  IEnumerator Refresh_()
2.     {
3.         Debug.LogWarning("TODO: 로딩 팝업 on.");
4.  
5.         rh.eLanguage language = tzGlobal.Instance.OPTION.language;
6.        
7.         string json = StreetUtility.LoadJsonFromStreamingAssets("notice.json");
8.         if (json != null)
9.         {
10.             // 필요한 부분만 분리.
11.             LitJson.JsonData data = LitJson.JsonMapper.ToObject(json);
12.             json = data[language.ToString()].ToJson();
13.            
14.             notice = LitJson.JsonMapper.ToObject<string[]>(json);
15.         }
16.  
17.         string path = string.Format("{0}/{1}/language", rh.Const.LOCALIZATION_PATH, language);
18.         json = StreetUtility.LoadJsonFromResources(path);
19.         if (json != null)
20.         {
21.             // json 로드.
22.             Dictionary<string, string> dic = LitJson.JsonMapper.ToObject<Dictionary<string, string>>(json);
23.  
24.             // dictionary 카피.
25.             dic_localization_text = new Dictionary<eTextKey, string>();
26.             eTextKey e;
27.             for (int i = 0; i < dic.Count; i++)
28.             {
29.                 e = (eTextKey)i;
30.                 dic_localization_text[e] = dic[e.ToString()];
31.             }
32.  
33.             // 등록된 localize 함수 실행.
34.             for (int i = 0; i < list_localize_method.Count; i++)
35.             {
36.                 complete = false;
37.                 list_localize_method[i].Invoke();
38.                 yield return new WaitUntil(() => complete);
39.             }
40.         }
41.  
42.         Debug.LogWarning("TODO: 로딩 팝업 off.");
43.     }

And here's my StreetUtility.cs

Code (CSharp):

1.  public static string LoadJsonFromStreamingAssets(string path_with_extention_under_streaming_assets_folder)
2.     {
3.         string json = null;
4.         try
5.         {
6.             //Android Platform
7. #if UNITY_ANDROID
8.             string oriPath = Path.Combine(Application.streamingAssetsPath, path_with_extention_under_streaming_assets_folder);
9.  
10.             WWW reader = new WWW(oriPath);
11.             while (!reader.isDone) { }
12.             string realPath = Application.persistentDataPath + "/" + path_with_extention_under_streaming_assets_folder;
13.             System.IO.File.WriteAllBytes(realPath, reader.bytes);
14.  
15.             path_with_extention_under_streaming_assets_folder = realPath;
16.  
17. #elif UNITY_IOS //IOS Platform
18.            
19. #elif UNITY_STANDALONE //PC Platform
20.             string full_path = string.Format("{0}/{1}", Application.streamingAssetsPath, path_with_extention_under_streaming_assets_folder);
21.             StreamReader reader = new StreamReader(full_path);
22.             json = reader.ReadToEnd().Trim();
23.             reader.Close();
24.  
25.             Debug.Log(json);
26. #endif
27.         }
28.         catch (Exception e)
29.         {
30.             Debug.LogWarningFormat("Failed to Load.\n{0}\n{1}", e, path_with_extention_under_streaming_assets_folder);
31.         }
32.         return json;
33.     }
34.    

and here is my .Json that is verified in https://jsonlint.com/ .

My problem here is that it's not getting the file . Please someone please help me out with this one.

 

It's not working because you aren't setting json = to the string you get in the Android section of your code, so when you return json, it returns null.

 

What do you mean sir? i don't quite understand

 

He means this line

Code (CSharp):

1. string json = null;
2. ///....
3. json = reader.ReadToEnd().Trim(); //THIS ONE

It is on your PC/Standalone compile section, but it isn't on your Android section. So json will always be null.

 

My PC/Standalone is working fine . So should i do it also on my #if UNITY_ANDROID ? like this?

Code (CSharp):

1. json = null;
2. while(!reader.isDone){}
3. json = reader.text;

 

Yeah

 

Thank you sir it's actually working now what i did is like this

json = null;
while(!reader.isDone){}
json = reader.text.Trim();
