byte to string android

So I'm using files to save some scores of my program but the problem is that I don't can't just print them. I tryed several things but I don't find the right one the is my code:

try{
        String FILENAME = "FrogScoreFile";
        FileInputStream fos = openFileInput(FILENAME);
        byte[] b = new byte[1];
        fos.read(b);
        fos.close();
        String score= String b;
        game5HighScore.setText(b);
        }catch (java.io.FileNotFoundException e) {
        } catch (IOException e) {
                e.printStackTrace();
    }

try{
        String FILENAME = "FrogScoreFile";
        FileInputStream fos = openFileInput(FILENAME);
        BufferedReader br = new BufferedReader(new InputStreamReader(fos));
        String yourText = br.readLine();
        br.close();
        game5HighScore.setText(yourText);
    }catch (java.io.FileNotFoundException e) {
    } catch (IOException e) {
            e.printStackTrace();
}

By The way. why not save your score with SharedPreferences Or SQLite database?

SharedPrefrences Guide.

public static void saveScore(Context context) {
    final SharedPreferences.Editor editor = context.getSharedPreferences(
            "settings", Context.MODE_PRIVATE).edit();
    editor.putInt("score", 100);
    editor.commit();
}

public static int readScore(Context context) {
    final SharedPreferences sp = context.getSharedPreferences("settings",
            Context.MODE_PRIVATE);
    return sp.getInt("score", 0);
}

You can convert Byte array to string by creating new string object.

byte[] b = new byte[1];
fos.read(b);
fos.close();
String message = new String(b);
