Hi,

I assume you mean a byte array and not a byte, because converting an image to a byte does not make much sense.

Have a look here:

Try this:

Java

// convert from bitmap to byte array
public byte[] getBytesFromBitmap(Bitmap bitmap) {
    ByteArrayOutputStream stream = new ByteArrayOutputStream();
    bitmap.compress(CompressFormat.JPEG, 70, stream);
    return stream.toByteArray();
}

Thank you, but probably you forgot to give that vote, :p.

No, I didn't forget to vote. It's a bug: it takes some time before the stars show up. You can find a post about it in the Bugs & Suggestions forum. For me, they show up fine now.
