How to open the options menu programmatically?

Apparently, doing it in onCreate breaks app, since Activity's not yet attached to a window. If you do it like so:

@Overridepublic void onAttachedToWindow() {    openOptionsMenu(); };

...it works.

For developers using the new Toolbar class of the Support Library, this is how it's done:

Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);toolbar.showOverflowMenu();
