Here is my Code : 

public class OpenERP extends  AsyncTask<Context, Void, Void>{


final String TAG = "ERP";  
 final String url = "192.168.1.11:8069";  
 final String db = "Rabii";  
 final String username = "admin"; 
 final String password = "123";  
 String a[] = new String[]{db, username, password}; 
 List<String> list = new ArrayList<String>(Arrays.asList("", "", "", "")); 
 Map emptymap = emptyMap();   List<String> list1 = new ArrayList<String>(Arrays.asList("", "", "", "", "")); 
 
 @Override   
protected Void doInBackground(Context... params) {     
 try {        
 final XmlRpcClient client = new XmlRpcClient();      
 final XmlRpcClientConfigImpl common_config = new XmlRpcClientConfigImpl();     
 common_config.setServerURL(new URL(String.format("%s/xmlrpc/2/common", url))); 

 int uid = (int)client.execute(    common_config, "authenticate", asList(db, username, password, emptyMap())); 
 
 final XmlRpcClient models = new XmlRpcClient() { { setConfig(new XmlRpcClientConfigImpl() {{ setServerURL(new URL(String.format("%s/xmlrpc/2/object", url)));               }}); 
 }         };         final Integer id = (Integer) models.execute("execute_kw", list2( db, uid, password,"pointage.task", "create",       
 asList(new HashMap() {{                  put("name", "New Partner");               }})         ));      }
 catch (MalformedURLException e) {         Log.e(TAG, "URL exception: " + e.getMessage());      }
return null ;   }  
 private List asList(String db, String username, String password, Map<Object, Object> objectObjectMap)
 {      return null;   }}
