#android bad base64

开发者在使用Android Base64库进行字符串转换时遇到问题，尝试将double类型转换为字符串后进行Base64编码，导致IllegalArgumentException。已排除默认、NO_WRAP等编码方式，寻求解决思路。

I am trying to encode and decode a String using android.util.Base64, but it gives a bad base-64 error.

The code with the problem is:

private byte[] base64ToByte(String str) throws IOException {

Log.i("encription", str);

byte[] returnbyteArray = Base64.decode(str, Base64.URL_SAFE);

return returnbyteArray;

}

The error logcat is:

The input(the str String from the code) looks like this:

08-09 13:02:18.539: I/encription(29827): 26.919047981500626

It is a double converted to a string, using:

String.valueOf(number)

The error is persistent with all encoding flags (DEFAULT, NO_WRAP, etc), any help would be apreciated, thank you.
