  <p>It has no effect, I did debugging and it enter in if part but without setting the list to empty, the list continue to appear ! I can't understand why, I appreciate your help.</p>
  
  <pre><code>final ProjectContainer container = gson.fromJson(resultat,
                      ProjectContainer.class);
              final ListView lv = (ListView) findViewById(R.id.list);
              TextView emptyList = (TextView) findViewById(R.id.emptyList);
              // if list empty
              if (container == null) {
                  lv.setEmptyView(emptyList);
                  emptyList.setText("No Projects Found");
  
              }
  </code></pre>
  
  <p>Thanks in advance.</p>
