android UTF8 encoding from received string

I am receiving a string that is not properly encoded like mystring%201, where must be mystring 1. How could I replace all characters that could be interpreted as UTF8? I read a lot of posts but not a full solution. Please note that string is already encoded wrong and I am not asking about how to encode char sequence. I asked same issue for iOS few days ago and was solved using stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding. Thank you.

You can use the URLDecoder.decode() function, like this:

String s = URLDecoder.decode(myString, "UTF-8");

Well this string is already encoded, you have to decode:

String sDecoded = URLDecoder.decode("mystring%201", "UTF-8");

so now sDecoded must have the value of "mystring 1".

The "Encoding" of String:

String sEncoded = URLEncoder.encode("mystring 1", "UTF-8");

sEncoded must have the value of "mystring%201"

Looks like your string is partially URL-encoded, so... how about this:

try {
 System.out.println(URLDecoder.decode("mystring%201", "UTF-8"));
} catch(UnsupportedEncodingException e) {
 e.printStackTrace();
}
