UTF-8 encoding in Volley Requests

Question

In my Android app I am loading json data with a Volley JsonArrayRequest. The data were created by myself and I saved them with Sublime with UTF-8 encoding. When

Answer 1

another approach: you can encode your whole response by this line of code.

newStr = URLDecoder.decode(URLEncoder.encode(oldStr, "iso8859-1"),"UTF-8");

I have encoded whole response string into UTF-8 as I know volley default encode method is iso8859-1

Answer 2

I have same problem like this and i solve it using UTF-8 charset.

String str = "";
try {
     str = new String(strFromService.getBytes("ISO-8859-1"), "UTF-8");
} catch (UnsupportedEncodingException e) {

 e.printStackTrace();
}

String decodedStr = Html.fromHtml(str).toString();

I hope this will work for you

Answer 3

donot use try{} catch in the onResponse block, that is giving some problem in my code , rather than that you can implement like this .

@Override 
onResponse(String s) {

s= fixEncoding(s);
Toast.makeToast(this,s,Toast.LENGTH_LONG).show();

}

and i think you will get the required result

 public static String fixEncoding(String response) {
            try {
                byte[] u = response.toString().getBytes(
                        "ISO-8859-1");
                response = new String(u, "UTF-8");
            } catch (UnsupportedEncodingException e) {
                e.printStackTrace();
                return null;
            }
            return response;
        }

Answer 4

If you know that absolutely all of the files you are requesting will be in the UTF-8 format, which it sounds like you do, then you might consider forcing your Volley request to return UTF-8 formatted strings. You could accomplish this by subclassing the standard JSON request. Something like this:

public class Utf8JsonRequest extends JsonRequest<JSONObject> {
    ...
    @Override
    protected Response<JSONObject> parseNetworkResponse (NetworkResponse response) {
        try {
            String utf8String = new String(response.data, "UTF-8");
            return Response.success(new JSONObject(utf8String), HttpHeaderParser.parseCacheHeaders(response));
        } catch (UnsupportedEncodingException e) {
            // log error
            return Response.error(new ParseError(e));
        } catch (JSONException e) {
            // log error
            return Response.error(new ParseError(e));
        }
    }
}

I had the same problem earlier two days ago and i have tried every thing my friends just said and it`s the same problem and i tried so meany things .. my file is written in php and using volley to get the data as json i followed these steps to solve the problem ..

1. before executing the query in your database write this query

   mysqli_query($this->connection,"set_NAMES_utf8");

2. use this header in your file if it`s php

   header('Content-Type: application/json ; charset=utf-8 ');

3. while you are echoing the json according to php there is a solve for this problem use this special charachter in json_encode($json,JSON_UNESCAPED_UNICODE)

   i hope it helped

Answer 6

Add this line of code inside response of volley :

 public void onResponse(String response) 
    {

     if (response != null) 
      {
        response=new String(response.getBytes("ISO-8859-1"), "UTF-8");
      }
   }
