android - Excepton with image_str = Base64.encodeBase64String(data); -


everytime when try convert byte array string, i´m getting exception. i´m getting byte array directly method:

public void onpicturetaken(byte[] data, camera arg1) {              image_str = base64.encodebase64string(data); }

this log:
