BitmapFactory.decodeByteArray returns null

Question

Looks good?

public static Bitmap stringToImage(String base64) {

    byte[] decodedString = decode(base64, Base64.DEFAULT);
    return BitmapFactory.decodeByteArray(decodedString, 0, decodedString.length);
}

this code returns null, if my base64 string starts with "data:image/jpeg;base64,". but if I remov this prefix - this code works fine! How to solve this problem?

I tested my base64 string and it works fine (comment 1 How to display Base64 images in HTML?)

I can to remove this prefix manually, but whether there is a class/method that will automatically remove it? — monyag, Jul 02 '12 at 05:14
using the regexp - Pattern.compile("^(data:image/.+;base64,).+"); Android does not contains a mime-type strip method :( — monyag, Jul 02 '12 at 09:29

Unless I'm confused, "data:image/jpeg;base64," is not a valid part of a base64 string. If that's the case, it's really no wonder it's not decoding correctly. Just remove it from the head of the string before you decode if it's causing problems.
