      public void onComplete(boolean success) { 
       dismiss(); // here i get error 
       updateDatabaseSize(); 
       updateFilters(); 
       MeasureUtils.makeDefaultTemplate(SettingsActivity.this, true); 
      } 
     }); 
     getCountriesTask.execute(SettingsActivity.this); 
     showProgress(); 
     updateDataBaseProfile(); 
    }

我的内部类

private class UpdateCountries extends UserOperationsTask { 
     final DialogProgressFragment progressDialog; 

     UpdateCountries(DialogProgressFragment progressDialog) { 
      super(UserOperationsTask.TaskMode.MODE_LOAD_COUNTRIES, null); 
      this.progressDialog = progressDialog; 
     } 

     @Override 
     public void onLoadFinished(Bundle resultData) { 
      setRegionLabels(); 
      updateFilters(); 
      hideProgress(); 
      String errorMessage = resultData.getString(UserOperationsTask.RESULT_ERROR_STRING); 
      if (errorMessage != null) { 
       Log.d(TAG, "getCountriesFromServer error: " + errorMessage); 
       showMessage(getString(R.string.info_title), getString(R.string.server_request_error)); 
      } else { 
       progressDialog.start(SettingsActivity.this, DialogProgressFragment.DialogMode.MODE_UPDATE); 
       progressDialog.setCancelable(false); 
       progressDialog.show(getSupportFragmentManager(), DialogProgressFragment.class.getSimpleName()); 
      } 
     } 
    }

请告诉我如何更好地解决这个问题？

尝试把更新过程在后台服务通知UI使用的广播接收机。 –
