Reading from a file not working on Android

Hi, I have this block of code which loads from a plain text file the info needed to create a bunch of blocks in my breakout-like game. It works perfect on windows, but when I export my project and install it on my android phone, the level shows empty (blockCount shows 0), I am assuming that the file isn't loading, but I see no errors and all the other game logic appear to work correctly.

Any ideas what could I be doing wrong? I tryed to manually copy the file to what I tought was the datapath on my phone, but the result was the same.

         sr = new StreamReader(Application.dataPath + "\\test.txt", Encoding.Default);
         using (sr) {
         
             do {
                 sLine = sr.ReadLine();
                 if (sLine != null) {
                     string[] sDatos = sLine.Split(',');
         
                     int iTipo = int.Parse(sDatos[0]);
                     
                     Vector2 targetPosition = new Vector2 (float.Parse(sDatos[1]),float.Parse(sDatos[2]));
                     GameObject newBlock = (GameObject)Instantiate(blocks[iTipo], targetPosition, Quaternion.identity);
                     newBlock.GetComponent<Rocas>().setHP(int.Parse (sDatos[3]));
                     blockCount++;
 
                     Debug.Log("Tipo : " + sDatos[0] + "\n");
                     Debug.Log("X,Y : " + sDatos[1] + "," + sDatos[2] + "\n");
                     Debug.Log("HP : " + sDatos[3] + "\n");
                 }
             }
             while (sLine != null);
               
             sr.Close();
         }

Thanks in advance!
