== Acceptance criteria
[] Add button to article action bar on mobile
[] Button must appear on all article namespace pages except the main page
[] When user selects button, Print menu should be triggered
[] This article action shows only for UA Android
[] Ensure button is instrumented to send events according to https://meta.wikimedia.org/wiki/Schema:Print
== Developer Notes
1. We can add lightweight instrumentation via [the StatsD subscriber protocol](https://github.com/wikimedia/mediawiki-extensions-WikimediaEvents/blob/0af36961a57b8634ea10b457f7791269f34b6b84/modules/ext.wikimediaEvents.statsd.js), i.e.
```lang=javascript
$( '.offline-download-btn' ).click( () => {
mw.track( 'counter.offline-download-btn-click', 1 );
} );
```

**Questions**
1. Since we don't have a backend, what will clicking the button trigger?
@phuedx: It doesn't really matter.
2. Should this be feature flagged? Yes.
@phuedx: In the short term, we could develop this feature in a feature branch and deploy it to the staging server.
