Android Directories with XML

When saving and loading XML, will the way the directories are saved and loaded change based on the OS?
I'm currently developing on Mac OSX and I got saving and loading working in Unity with XML, however when I run on the Android it no longer works.

I suspect the way I handle the directories is the problem because I had to adjust them for the source code I found.
Here's what I have that works on my Mac, but not on the Android as far as I can tell.

Code (csharp):

1. // Saves out the XML. Should not be called by anything except this class.
2. private void CreateXML()
3. {
4.     // Mac Saves might work differently than on other computers. Look into it.
5.     // "//" Might be needed for on Android
6.     StreamWriter writer;
7.     FileInfo t = new FileInfo(m_FileLocation + m_FileName);
8.        
9.     if(!t.Exists)
10.         writer = t.CreateText();  
11.     else
12.     {
13.         t.Delete();
14.         writer = t.CreateText();
15.     }
16.    
17.     writer.Write(m_data);
18.     writer.Close();
19.     Debug.Log("File written.");
20. }
21.    
22. // Loads the XML. Should not be called by anything except this class.
23. private void LoadXML()
24. {
25.     // Mac Loads differently. Other systems will want "//" possibly.
26.     StreamReader r = File.OpenText(m_FileName);
27.     string _info = r.ReadToEnd();
28.     r.Close();
29.     m_data = _info;
30.     Debug.Log("File Read");
31. }
