Ways to convert image to base64 in java?

Question

Java

There is a certain ImageView in which the image lies. It is required to transfer the image to the server using the POST method. On the server, the data is processed by a php script.

img = photoHolder.getDrawable();
BitmapDrawable bitmapDrawable = ((BitmapDrawable) img);
Bitmap bitmap = bitmapDrawable .getBitmap();
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream);
imageInByte = stream.toByteArray();

And somewhere below

String img = new String(Base64.encode(imageInByte, Base64.DEFAULT));
String myParams = "img="+img;

Everything seems to work ... But the images do not open. Obviously, I'm converting to base64 incorrectly somehow..
But just in case, here's the image processing code

$img1 = base64_decode($img);
$filename = "img/asd.jpg";
file_put_contents($filename, $img1);

What's wrong?

Answer 1

So encode the same image on the server and compare, maybe the problem is just in the encoding, not in the one that is base64, but in the one in which the bytes are presented in the request - UTF-8 or 1251, start with something simpler, better with plain text files of several bytes.

- Good! *picks up mouse from table and clicks on RESET*
