Questions & Answers

This what I have written so far and it works fine in the editor but when I try it on my android phone it doesnt work. So what am I doing wrong?

using UnityEngine;
using System.Collections;
using System.IO;
using System.Text;

public class AndroidScoreSavingTest : MonoBehaviour {

string message;
string loadMessage = "Yeah working";
string data;
FileInfo f; 

void Start()
{
	f = new FileInfo(Application.dataPath + "\\" + "myFile.txt");
	Screen.SetResolution(800, 600, true);
}

void OnGUI()
{
	GUILayout.BeginArea(new Rect(0,0,500,500));
	GUILayout.Label(message + " " + data);
	if(GUILayout.Button("Save"))
	{
		
		if(!f.Exists)
		{
			message = "Creating File";
			Save();
		}
		else
		{
			message = "Saving";
			Save();
		}
	}
	if(GUILayout.Button("Load"))
	{
		if(f.Exists)
		{
			Load();
		}
		else
		{
			message = "No File found";	
		}
	}
	GUILayout.EndArea();
}

void Save()
{
	StreamWriter w;
	if(!f.Exists)
	{
		w = f.CreateText();	
	}
	else
	{
		f.Delete();
		w = f.CreateText();
	}
	w.WriteLine(loadMessage);
	w.Close();
}

void Load()
{
	StreamReader r = File.OpenText(Application.dataPath + "\\" + "myFile.txt");
	string info = r.ReadToEnd();
	r.Close();
	data = info;
}

}

On android you might not have direct write access to the dataPath of the project.

Try using Application.persistentDataPath instead. This is where save files are intended to be stored.

I needed to load json and similar text files into my Android game. Unfortunately I could not access the internal memory from the Application.persistentDataPath, so when I searched, I found this amazing tool that helped me use these functions, and it only cost $ 9.90. Now I can read and write files in internal memory, manage files and folders, and so on.

I hope this helps anyone who is reading in the future!
