Unity - Read JSON file From android [duplicate] - json

Question

This is how i read my textfile in android.
#if UNITY_ANDROID
string full_path = string.Format("{0}/{1}",Application.streamingAssetsPath, path_with_extention_under_streaming_assets_folder);
// Android only use WWW to read file
WWW reader = new WWW(full_path);
while (!reader.isDone){}
json = reader.text;
// PK Debug 2017.12.11
Debug.Log(json);
#endif
and this is how i read my textfile from pc.
#if UNITY_STANDALONE
string full_path = string.Format("{0}/{1}", Application.streamingAssetsPath, path_with_extention_under_streaming_assets_folder);
StreamReader reader = new StreamReader(full_path);
json = reader.ReadToEnd().Trim();
reader.Close();
#endif
Now my problem is that i don't know how to write the file on mobile cause i do it like this on the standalone
#if UNITY_STANDALONE
StreamWriter writer = new StreamWriter(path, false);
writer.WriteLine(json);
writer.Close();
#endif
Help anyone

You can't save to this location. Application.streamingAssetsPath is read-only. It doesn't matter if it works on the Editor or not. It is read only and cannot be used to load data.
Reading data from the StreamingAssets:
IEnumerator loadStreamingAsset(string fileName)
{
string filePath = System.IO.Path.Combine(Application.streamingAssetsPath, fileName);
string result;
if (filePath.Contains("://") || filePath.Contains(":///"))
{
WWW www = new WWW(filePath);
yield return www;
result = www.text;
}
else
{
result = System.IO.File.ReadAllText(filePath);
}
Debug.Log("Loaded file: " + result);
}
Usage:
Let's load your "datacenter.json" file from your screenshot:
void Start()
{
StartCoroutine(loadStreamingAsset("datacenter.json"));
}
Saving Data:
The path to save a data that works on all platform is Application.persistentDataPath. Make sure to create a folder inside that path before saving data to it. The StreamReader in your question can be used to read or write to this path.
Saving to the Application.persistentDataPath path:
Use File.WriteAllBytes
Reading from the Application.persistentDataPath path
Use File.ReadAllBytes.
See this post for a complete example of how to save data in Unity.

Answer 2

This is the way I do it without the WWW class (works for Android an iOS), hope its useful
public void WriteDataToFile(string jsonString)
{
if (!Directory.Exists(folderPath))
{
Directory.CreateDirectory(folderPath);
}
if (!File.Exists(filePath))
{
File.Create(filePath).Close();
File.WriteAllText(filePath, jsonString);
}
else
{
File.WriteAllText(filePath, jsonString);
}
}
