In Android, How to decode UTF-8 encoded String?

Question

I 'm using following data to decode the UTF-8 encoded String.

. Output is same as input. What is the issue?

Method:

public String decodeString(String encodedString) {
            return new String(encodedString.getBytes(), "UTF-8");

    }

It is. You can decode it here: mothereff.in/utf-8 , and result would be fine. — Usman Rana

Please post more code so it is reproducable for us. It's pretty unclear what you are doing now. For instance you should start with a string initialized and then String encodedString = .....; and so on. — greenapps

There is nothing to check if you do not provide reproducable code. We cannot even see how and with what you call that function. We do not know what that parameter encodedString contains. So show full code. — greenapps

Just Use String result = URLDecoder.decode(string, "UTF-8");

Or use this

byte[] data = Base64.decode(base64, Base64.DEFAULT);
String text = new String(data, "UTF-8");

No gain, URLEncoder and String encoding has a difference. You can check at these links with same values, result would be different: mothereff.in/utf-8 freeformatter.com/url-encoder.html#ad-output

use this

String s2 = new String(bytes, "UTF-8"); // Charset with which bytes were encoded

and if it doesn't work for you

String decoded = new String(encoded.getBytes("ISO-8859-1"));
