"yes"?

[Tima Vaisburd, 2017/03/20 05:06:04]

string/unknownName to the rescue. The android:title must be present, and the
actual title string does not matter because it is always reset in the code. I
changed to "unknownName" because it is a better fit.

         android:alphabeticShortcut="x"

what does do exactly?

+        android:orderInCategory="2"

[boliu, 2017/03/11 00:37:52]

aren't these ordered before? why is it important explicitly specify this now?

[Tima Vaisburd, 2017/03/20 05:06:04]

The difference is that now I try to add a menu item dynamically (and want it to
be first).
The Android method Menu.add() has "order" argument, however, this order does not
work in the most intuitive way. My experiments and googling showed that you
either need to add the order to every item (e.g. Android does this in the Java
code,
https://cs.corp.google.com/android/frameworks/base/core/java/android/widget/E...),
or you need to give the category to every item.

It seems you do not need both though. I left "orderInCategory" to follow what
Android code does.
