Read and Write Textfile on mobile (C# Unity )
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
