I'm trying to hide some menu items when a fragment is changed, but seems that this is not working. Here is what im doing:
Defining the menu and menu items:

```
@Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu items for use in the action bar
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.actionbar_sharecall, menu);

        actionMenu = menu;
        MenuItem searchItem = menu.findItem(R.id.action_searchmenuitem);
        MenuItem item = menu.findItem(R.id.action_menushare);
        // item.setVisible(false);
        // searchItem.setVisible(false);

        topSearch = searchItem;
        topShare = item;
        final MRShareActionProvider actionProvider = new MRShareActionProvider(
                this);
        MenuItemCompat.setActionProvider(item, actionProvider);
        actionProvider
                .setShareHistoryFileName(ShareActionProvider.DEFAULT_SHARE_HISTORY_FILE_NAME);
        actionProvider.setOnShareTargetSelectedListener(this);
        actionProvider.setShareIntent(createShareIntent());
        return true;

    }

```

changing the fragment and changing the visibility:

```
  //changing visibility    
    topSearch.setVisible(false);
    frag = new SyncFragment();
    FragmentTransaction ft = getSupportFragmentManager()
    .beginTransaction();
    ft.replace(R.id.fragment_content, frag);
    ft.commitAllowingStateLoss();

```

and this is my SyncFragment:

```
public class SyncFragment extends MRBaseACBFragment {

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        return inflater.inflate(R.layout.fragment_sync, null);
    }

}

```

but after the fragment is changed, i can still see the menu item. Can someone help me with a solution on how to do this?
