我在解码Base64编码图像时遇到问题。例如，我从服务器获得以下字符串：

我在这里找到的Online Tool正确地解码了String但是代码我在这里用过：

byte[] imageAsBytes = Base64.decode(imageString.getBytes(), Base64.DEFAULT);

Bitmap bitmap = BitmapFactory.decodeByteArray(imageAsBytes, 0, imageAsBytes.length);

产生错误：

02-02 19:16:56.460: E/AndroidRuntime(18237): java.lang.IllegalArgumentException: bad base-64

问题出在哪里？我想如果它不是一个有效的Base64编码字符串，我提供的链接中的在线工具也无法解码它。

修改

发现了另一个Online Tool：

The input is not a valid Base-64 string as it contains a non-base 64 character, more than two padding characters, or an illegal character among the padding characters.

但它不知道在哪里。我删除了填充＆＃39; =＆＃39;但它没有改变。

Answer 1

我不知道这是正确的解决方案，但在我的情况下，我从上面的回复中删除了起始部分data:image\/jpg; base64,，它对我有用。这是不是编码数据部分的数据。

Android base64编码的字符串无效？
