Reading files in Unity from different platform

Questions & Answers
1

I’m using JSON to store data.

As these data are required at the start of the game,
I would like to read the file as soon as the game starts.

my JSON files are currently stored under /Asset/Resources/Tables/_____.json

On PC,
I am appending UnityEngine.Application.dataPath with rest of the subpaths to read data using native C# file I/O libraries (i.e. StreamReader)

However, it seems such technique does not work for Android.

What’s the best way to store and read JSON files in Unity games that support multiple platforms?

Thanks in advance,

public static void CreateFile(string path, string fileName){
if(!File.Exists(path+“/”+fileName)){
File.Create(path+“/”+fileName).Dispose();
}
}

public static void WriteFile(string path,string fileName,string data){
if(File.Exists(path+“/”+fileName)){
StreamWriter sw = new StreamWriter(path+“/”+fileName);
sw.WriteLine(data);
sw.Flush();
sw.Close();
}
}

public static string ReadFile(string path,string fileName){
string output=“”;
if(File.Exists(path+“/”+fileName)){
StreamReader sr = new StreamReader(path+“/”+fileName);
output=sr.ReadLine();
sr.Close();
}
return output;
}

public static string GetAppDataPathIOS(){
	string path=Application.dataPath.Substring(0,Application.dataPath.Length-5);	
	path=path.Substring(0,path.LastIndexOf('/'));
	return path+"/Documents";
}

public static string GetAppDataPathAndroid(){
	return Application.persistentDataPath;
}

You may want to look into using Application.persistantData instead of Application.dataPath. I traced out the paths that persistantData gave on Windows and Android platform and these were the results I got:

Windows: “C:/Users/USERNAME/AppData/LocalLow/Company/ProductName”

Android(internal): “/data/data/com.Company.ProductName/files”

Android(external): “/storage/emulated/0/Android/data/com.Company.ProductName/files”
