try code....

picturecallback mypicturecallback_jpg = new picturecallback() {      @override     public void onpicturetaken(byte[] data, camera arg1) {          bitmapfactory.options opt;          opt = new bitmapfactory.options();         opt.intempstorage = new byte[16 * 1024];         parameters parameters = arg1.getparameters();         size size = parameters.getpicturesize();          int height11 = size.height;         int width11 = size.width;         float mb = (width11 * height11) / 1024000;          if (mb > 4f)             opt.insamplesize = 4;         else if (mb > 3f)             opt.insamplesize = 2;          //preview camera         bitmap bitmap = bitmapfactory.decodebytearray(data, 0, data.length,opt);        } }
