* Use dark navigation bar on dark theme
This approach uses `tools:targetApi` instead of separate theme file and
avoids lint errors.
* Use dark navigation bar in QR scanner activity
This is consistent with the black background that is already used in
that activity.
There are countless arguments on both sides of the Jabber ID vs XMPP address
debate which makes deciding between them a really tough decision.
Pro Jabber ID
* Jabber is easier pronounce
* We have always called it Jabber
* Jabber is more recognizable (This claim can not be backed up by Google Trends)
* Jabber ID has a nicer typography
Pro XMPP address
* People like the term address. People also liked 'Chat address' or
'Conversations address'. Address is also used in Email address or other
protocols. Even if people don’t understand the 'XMPP' part of the term they
might understand the 'address' part and know what is going on.
* While people might have heard of Jabber rather than XMPP; people have heard
of it in the 00s and associate it with something old. Depending on the
target audience this is a good thing. And people who value sustainability
know what XMPP is anyway.
* Jabber is a Cisco product. If we were to succeed in making 'Jabber' cool
again we don’t want to share that success with Cisco. What has Cisco ever
done for us? Aside from providing us with a venue for the XSF summit. And
building nice aqueducts.
* The Cisco owned trademark is a damocles sword. While the XSF technically
has the right to hand out sublicenses to use the term this can be a lengthy
process. And automated filter system that for example monitor Google Play
store descriptions don’t care that the XSF has the rights or that the terms
of use are more nuanced. They just see a trademark and reject the
publication. And we all know how impossible it is to speak to an actual
human at Google.
