Android base64转bitmap 报错 java.lang.IllegalArgumentException: bad base-64

public static Bitmap stringtoBitmap(String string) {
//将字符串转换成Bitmap类型
Bitmap bitmap = null;
try {
byte[] bitmapArray;
//就是这一句报错：java.lang.IllegalArgumentException: bad base-64
bitmapArray = Base64.decode(string, Base64.DEFAULT);
bitmap = BitmapFactory.decodeByteArray(bitmapArray, 0, bitmapArray.length);
} catch (Exception e) {
e.printStackTrace();
LecoUtils.Log("转图片 e=" + e);
}

return bitmap;
}
这是我传入的从网上获取的base64生成的图片：data:image/png;base64,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
然后老转换不过来，老报错，求大神指点

把头的那小段去掉，保留纯正的BASE64部分 data:image/png;base64, 不要。

我试过，不行啊，光传个 iVBORw0KGgoAA...............QAAAABJRU5ErkJggg=或者是传个base64, iVBORw0KGgoAA...............QAAAABJRU5ErkJggg=都不行，还是在那句报同样的错误，请问您觉得还可能是什么情况呢？

追答

bitmapArray = Base64.decode(string, Base64.DEFAULT);
这段，得到的就是一个二维码的图片，jpg的。

后面的生成bitmap不正确，是JPG，不是BMP的

那我怎么样用代码把那些一长串的base64转成bitmap呢？
