I'm sending information from Android to a PHP WebService through the Volley lib. Everything works perfectly except with special characters.

Map<String, String> params = new HashMap<String, String>();
params.put("nome", "áàâãõóòúç");

If the name is equal to - nome = Maria das Graças for example, it gives me this error:

Error output:

  W / System.err: at org.json.JSONTokener.syntaxError (JSONTokener.java:450) > W / System.err: at org.json.JSONTokener.nextValue (JSONTokener.java:97)

In PHP I had the same problem at first and solved using the utf8_encoder function.

You need to encode before sending any string with special characters through your JSON .

Try using the class URLEncoder , something like this:

String nome = URLEncoder.encode("áàâãõóòúç", "utf-8");
