        if(br.readLine() != null)
        {
                            Log.d("File", "Value : " + br.readLine() );
            player = br.readLine();
        }
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

Which value is null?

At if(br.readLine() != null) you are reading in the first line of the file.

At Log.d("File", "Value : " + br.readLine() ); you are at the second line of the file.

At player = br.readLine(); you are reading the third line of the file. If there is only one line in the file, this line will return null.

Try:

try {
    String temp;
    InputStream fis = game.getFileIO().readFile("AFC/save.txt");
    BufferedReader br = new BufferedReader(new InputStreamReader(fis));
    if((temp = br.readLine()) != null)
    {
          player = temp;
          Log.d("File", "Value : " + player );
    }
} catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}
