Hi you need to use ProviderManager first, otherwise search will not work properly.Below is my working code which works perfectly, Hope it will help:

            try {

                Form searchForm = search.getSearchForm("search."+mXMPPConnection.getServiceName());
                Form answerForm = searchForm.createAnswerForm();

                answerForm.setAnswer("search", searchString);  
                org.jivesoftware.smackx.ReportedData data = search.getSearchResults(answerForm,"search."+mXMPPConnection.getServiceName());  

                if(data.getRows() != null)

                        System.out.println(row);
                        Iterator iterator = row.getValues("jid");

                            l.add(value);
                            System.out.println("Iteartor values......"+value);
                        }

                }
            } catch (Exception e) {
                System.out.println("Exception in Loading user search"+e);
            }
            return l;
        }

Answer 2

Try this. It solves my problem.

UserSearchManager search = new UserSearchManager(mXMPPConnection);  

Form searchForm = search.getSearchForm("search."+mXMPPConnection.getServiceName());

Form answerForm = searchForm.createAnswerForm();  
answerForm.setAnswer("Username", true);  

answerForm.setAnswer("search", user);  

org.jivesoftware.smackx.ReportedData data = search.getSearchResults(answerForm,"search."+mXMPPConnection.getServiceName());  

if(data.getRows() != null)
{
    Iterator<Row> it = data.getRows();
    while(it.hasNext())
    {
        Row row = it.next();
        Iterator iterator = row.getValues("jid");
        if(iterator.hasNext())
        {
            String value = iterator.next().toString();
            Log.i("Iteartor values......"," "+value);
        }
        //Log.i("Iteartor values......"," "+value);
    }
    Toast.makeText(_service,"Username Exists",Toast.LENGTH_SHORT).show();
    );
}

If Server has not any entery with that specified name then Itearator it has no value and code will not go inside while(it.hasNext).
