AsyncTask를 확장하는 클래스에서 오류가 발생했습니다.

Question

저는 내 dotnet webservice에서 데이터를 가져 와서 json 형식으로 결과를 내 안드로이드 응용 프로그램에 전달하려고했습니다. json 데이터는 invokeJSONWS을 호출하여 doInBackground 함수 (재정의 됨)에서 검색됩니다. 이것은 내가 publishProgress 메서드를 호출하려고 할 때 오류가 발생합니다. json 데이터를 publishProgress 메서드에 전달해야합니다. 반환 형식이 문자열 []이므로 publishProgress을 재정의해야합니다.

private class ChartTask extends AsyncTask< String,Void, Void>{ 

    // Generates dummy data in a non-ui thread 
    @Override 
    protected Void doInBackground(String... params) { 
     int i = 0; 
     invokeJSONWS(params[0],"PopulateCities"); 
     return null; 
     try{ 
      do{ 
       String [] values = new String[2]; 
       Random r = new Random(); 
       int visits = r.nextInt(27); 

       values[0] = Integer.toString(i); 
       values[1] = Integer.toString(visits); 

       publishProgress(values); 
           //Error here:The method publishProgress(Void...) in the type AsyncTask<String,Void,Void> is not applicable for the arguments (String[])      
       Thread.sleep(1000); 
       i++; 
      }while(i<=30); 
     }catch(Exception e){ } 
     return null; 
    } 

    // Plotting generated data in the graph 
    @Override 
    protected void onProgressUpdate(String[] values) { 
     visitsSeries.add(Integer.parseInt(values[0]), Integer.parseInt(values[1])); 
     mChart.repaint(); 
    } 
      //error here:The method onProgressUpdate(String[]) of type MainActivity.ChartTask must override or implement a supertype method 

} 


//Method which invoke web methods 
public void invokeJSONWS(String country, String methName) { 
    // Create request 
    SoapObject request = new SoapObject(NAMESPACE, methName); 
    // Property which holds input parameters 
    PropertyInfo paramPI = new PropertyInfo(); 
    // Set Name 
    paramPI.setName("country"); 
    // Set Value 
    paramPI.setValue(country); 
    // Set dataType 
    paramPI.setType(String.class); 
    // Add the property to request object 
    request.addProperty(paramPI); 
    // Create envelope 
    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
      SoapEnvelope.VER11); 
    envelope.dotNet = true; 
    // Set output SOAP object 
    envelope.setOutputSoapObject(request); 
    // Create HTTP call object 
    HttpTransportSE androidHttpTransport = new HttpTransportSE(URL); 

    try { 
     // Invole web service 
     androidHttpTransport.call(SOAP_ACTION+methName, envelope); 
     // Get the response 
     SoapPrimitive response = (SoapPrimitive) envelope.getResponse(); 
     // Assign it to static variable 
     responseJSON = response.toString(); 

    } catch (Exception e) { 
     e.printStackTrace(); 
    } 
} 


@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    getMenuInflater().inflate(R.menu.activity_main, menu); 
    return true; 
} 

}
