Menu item is not getting visible

I am inflating a menu item dynamically after specific event occurs. But menu item is not getting visible.

Below is code:

LocalBroadcastManager.getInstance(context).registerReceiver(new BroadcastReceiver() { @Override public void onReceive (Context context, Intent intent){ appCompatActivity.supportInvalidateOptionsMenu(); setHasOptionsMenu(true); setUpdateText(); appCompatActivity.invalidateOptionsMenu(); } }, new IntentFilter(UPDATE_ACTION)); void setUpdateText() { if (mainMenu != null) { mainMenu.findItem(R.id.notificationdevicemenu).setVisible(true); mainMenu.findItem(R.id.notificationdevicemenu).setEnabled(true); } } 

And I'm inflating menu like below:

 @Override public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) { super.onCreateOptionsMenu(menu, inflater); mainMenu=menu; menu.clear(); try { inflater.inflate(R.menu.main_list_fragment, mainMenu); } catch (Exception e) { e.printStackTrace(); } } 

Can anyone please tell me why menu is not getting visible. Any kind of help will be appreciated.
