Hi,
No, that is not correct understanding. Mobile is well maintained and developed
further - just like the desktop and embedded platforms.
We are constantly investing to the mobile and improving it with each release.
For all the new features we always aim to get it running cross-platform,
including mobile, whenever possible. So the functionality of mobile grows
constantly, just like desktop and embedded.
I do understand that you would like to have more of the device related items
(volume control, brightness, ...) captured to a Qt API. But lack of this should
not be seen as equal to lack of investment to mobile. What I wrote about it
being relative easy to implement could be seen positively as well - at least I
did not mean it in any way negative or insulting.
Yours,
Tuukka

So am I correct interpreting that Qt on mobile is "finished", and we're on
our own? (Aside from maintenance) Your statement "often quite straightforward
to capture in a cross-platform API." seems like a "let them eat cake" moment. I
really think you are missing the point that these "straightforward" are
anything but. Who knows Objective C and Java? Not many. Not to mention there
are enough pain points in moving to another platform already. I believe the
promise of cross platform Qt is at least to handle the code.
What would it take to get Qt to commit to supporting device APIs?

and new Qt features work nicely on mobile and in making sure new mobile
platforms are supported swiftly. A lot of effort was put to WinRT / UWP to be
supported in addition to iOS and Android. It is true that we have not been
actively extending the support for device APIs, even though these are often
quite straightforward to capture in a cross-platform API.

Without these APIs, my organization will not be able to justify continued usage
of Qt. I have to continually defend our selection of Qt. I've never spoken to
someone who was happy to have to use Qt. Xamarin, Flutter, and ReactNative are
what other developers want to use. I cannot expect to continue to win this
fight as Qt falls behind.

Java) This is a huge pain point, considering that is the fundamental problem
that Qt claims solve. Except it doesn't... on Mobile. It's not like I'm asking
for bleeding edge APIs. Qt started supporting iOS & Android 12th Dec 2013 with
Qt 5.2. In the 5 years since, none of the above have made it in and those are
pretty basic features. Since that time there were some early iOS accessibilty
additions and Android service capabilty. That's it.

That's what I mean when I say I want a transparent roadmap for mobile.
