Convert byte array to a string - - With Performace Android

Question

Bitmap foto = b.getBitmap();

byte[] bytes = null;
ByteArrayOutputStream ba = new ByteArrayOutputStream();
foto.compress(Bitmap.CompressFormat.JPEG, 100, ba);
foto.recycle();
foto = null;

bytes = ba.toByteArray();

String bBytes = Arrays.toString(bytes);

I'd like this method to return a String of the Byte values. For example, it would be : "12,23,34 ...." .

Here is how you can do it.

import java.util.Arrays;

public class Test {

    public static void main(String[] args) {
        byte[] bytes = {1,2,3,12};
        String bBytes = Arrays.toString(bytes);
        bBytes = bBytes.replaceAll(" ", "");
        bBytes = bBytes.replaceAll("\\[", "");
        bBytes = bBytes.replaceAll("\\]", "");
        System.out.println(bBytes);     
    }

}
