Now, those dreams become reality.

Ladies and Gentlemen I have the honor and the privilege to announce
the immediate availability of *NECESSITAS* suite.

What does „ncecessitas” mean and what is it?

 Necessitas is a latin word (Roman goddess of necessity) and it means:
necessity. It has more profound and powerful meanings, please check:
http://www.whiterosesgarden.com/deities/DTY_Roman/necessitas.htm and
you'll understand what I mean :). Why don’t I  use "Qt" and/or
"Android" words? Because Nokia "recommended" me NOT to use "Qt",
because more than 4 weeks ago I sent a mail to Google about "android"
word and I get didn’t get an answer until now. Why latin? I don't
know, maybe because I'm a latin :)

 I also bought a domain name for this project it's called
"licentia.eu", yes another latin word :) (http://
catholic.archives.nd.edu/cgi-bin/lookit.pl?latin=licentia), it means
freedom, liberty. I choosed licentia.eu as domain name and necessitas
as a subdomain because I don't want to stop here :).

Necessitas is a Qt suite for Android platform containing the following
components:
 - Ministro (http://www.archives.nd.edu/cgi-bin/lookit.pl?
latin=ministro) is a system wide qt libraries installer/provider (you
can download the latest version from http://sourceforge.net/projects/ministro.necessitas.p/files).
 - Qt framework.
 - Qt Creator for Android. (you cand download the package from
http://sourceforge.net/projects/necessitas/files). For a seamless
debugging exepience I recommend you to replace official gdb with a
newer one from: http://code.google.com/p/android-lighthouse/downloads/detail?name=gdb...

Thanks to Damien Buhl, you can find high quality documentation at
http://sourceforge.net/p/necessitas/wiki/Home/. Thank you again
fellow, without your help this release would not have been possible.

Before we get further I want to be crystal clear: This is an ALPHA
release! Is not meant to be used in production, PLEASE don't deploy
apps on Android Market because THE API IS NOT STABLE, please wait
until Nokia (or us) will ship at least a beta version! I deployed a qt
example (Animatedtiles) to Android Market ONLY to test Ministro
package promise, but it will be removed soon.
So, why this release is that important?
IMHO, for this project, this is the MOST important release ever, why?
Because now I'll put in your hands all the tools you need to begin
hacking on this project, and also to begin working on your apps,
because now, I hope, all the skeptic folks out there, will see the
potential of this project and will join us. Because Qt API is not
frozen yet, and if we need to add some API to Qt framework, now we
have a good chance to push them to upstream Qt.

Also I want to make clear one more thing, this project is community
work, Nokia and/or Google are not involved directly (yet, I hope :P )!
Also, I'm very grateful to Google because they made a wonderful truly
*free* O.S., I'm very grateful to Google because they have open minds
and they allowed this to happen, I'm very grateful to Trolltech and
Nokia because they made the best C++ framework ever: Qt framework, I'm
very grateful to Trolltech and Nokia because they made a first class
IDE for that framework.

Now the boring technical part:

What is done:

Ministro:
 It was the most critical missing piece of this project, without it
this project is almost worthless, this installer/provider is the
guarantee that all your apps will run on ALL android platforms WITHOUT
any modification! (ok, you also can compile qt statically (or worst
put all qt libs into your apk) but your application will target only
one andriod platform).

How it works:
 - when your application starts, it searches for Ministro service, if
the service is not installed, your applications will open the android
market and request user to install it (it also starts the search for
the user).
 - (after the service is installed) the application connects to
Ministro service, it  gives a list of qtmodules and waits
(patiently :) ) for Ministro's callback.
 - Ministro downloads all necessary libraries (only if they are
missing), and callbacks the application and gives it a list with all
necessary libraries to run.
 - the application loads all libraries provided by Ministro service
and finally it starts.

Known issues:
Sometime it receives corrupt data from the server (I didn't had enough
time to investigate this problem, I just try to download it again).

Qt Framework:
 - Most of Qt framework is ported or in progress. This relase is
shipped only with "sw" platform plugin.
 "sw" - comes from SingleWindow, this plugin uses only one Android
native window to draw all qt top level windows (IT DOESN'T mean you
can't have more then one top level window in Qt, like dialogs, menus,
combo-boxes, etc. ). Actually this plugins uses Nokia's framebuffer
implementation (IMHO this is very good because we don't need to
maintain our own plugin), I only made simple connections between
Nokia's plugin and android system. The ONLY problem this plugin has,
is that  it doesn't support hardware acceleration so no OpenGL. For
OpenGL I need to resurrect "mw" plugins, I'll do it after sw plugin
will be production stable.

 - The java part is cleanup and it provides only necessary
implementation for sw plugin.
"eu.licentia.necessitas.industius" (http://catholic.archives.nd.edu/
cgi-bin/lookit.pl?latin=industius) is the package name for qt
framework java part and probably
"eu.licentia.necessitas.mobile" (http://catholic.archives.nd.edu/cgi-
bin/lookit.pl?latin=mobile) will be for QtMobility part.

(A lot of :) ) Known issues:
http://code.google.com/p/android-lighthouse/issues/list?can=2&q=&sort...

Qt Creator for Android:
I think the following five words will discribes perfectly what is it:
Create, Manage, Compile, Deploy, Debug.
There are a lot of things to tell you about Qt framework <--> Qt
Creator integration, sadly my English is not good enough to do it, so
I'll let this images to speak for me: http://blip.tv/file/4790125 or
if you prefere youtube: http://www.youtube.com/watch?v=IMXUsfqUgYM
(youtube video was speedup al little bit to fit in 15 minutes youtube
restriction).

Known issues:
Sometime it hangs big time, it seems I've done something wrong
there :)

Necessitas SDK.
Known issues:
You must install it into /opt/necessitas folder.
For some misterious reason, the uninstaller, doesn't remove the icon
from your desktop.

Before I end this announce I'd like to thanks you all for your support
and consideration. Also, I want to apologizes, because it took such a
long time to release this SDK, but please understand that is very hard
to do everything almost alone (and don't forget, I had to do it only
in my free time, it doesn't mean I hate my job, I'm happy with my
current job, with what I'm doing every day (even if is not directly
related with qt, but keeps my brain in good shape), I'm proud to be
part of a great top developers team). It is extremely hard to think to
big things and also to be very carefull to the details, that’s why
you'll probably find a lot of stupid bugs, I also apologize for that
too. Also, I want to thank to all pure souls, who helped me with this
release.

I have a dream today, I have a dream that now, you'll be convinced by
this project’s potential and you'll join us in this beautiful journey,
and together, will finish this wonderful project. (Now it’s time for
you to say: keep on dreaming, sonny, keep on dreaming :) )

Seriously, now you have to decide what you want to do: you want to buy
Elot Savior bullshit about WP Nokia phones, and start learning a new
language made in Micro$oft labs, and silly-light (oh, sorry, shitty-
light, sorry again, one more try: silverlight, whew, is hard ..)API,
with, God knows how many, hidden patents which they will use them to
sue you, when they'll go down (see what happened with Google when they
tried to used java)? Or you want to stay with the most advanced and
free language and with the most advanced c++ framework and (soon) to
target millions of real phones (this phones are in peoples hands, now,
not in the Elot's dreams!), with the most used mobile O.S out there?
It's your choice!

This is awesome! You made my day better as I was very bored and angry
working on some of my projects whereas now I can play and start making
something good, finally for Android! I will check out code and everything
else in just few minutes and maybe try to make Arch Linux package. Thanks
again! :)

Now I just wonder of Necessitas will allow me to use D considering
there will be ready QtD port?

Sincerely,

That is great! Thank you for your continued effort and working on your dream!

Thank you!

I have question, again, about qt libs on sd card. I installed your demo and
after checking it I moved qt libs and demo to sd card by using some button
in settings. It works! Does it mean that libs are on sd card now or just
sinistry(?) application? Thanks.

Which one should I update ? Now you don't need to do anything special
to your qt application, just open it with QtCreator and follow the
steps.

Hi BogDan;

I'd like to build without Qt Creator also, updating the QtAnimatedTiles
example would be a great start :-)

(Also note that there is still examples/android and examples/android_sw
confusion).

Nice, I wish I could help for the Mac OS X port. Go Qt! :-) -- How about the
QML thingy?

QML is working well. I didn't find any major issues.

You need both android sdk & ndk, like explained in the documentation there:
http://sourceforge.net/p/necessitas/wiki/Setup%20QtCreator/

Note that only last versions of the sdk and ndk are usable.

I will come on the IRC channel tomorrow and I will be there for 2 weeks,
I hope I'll be able to help you.

Kindest regards,

Thank You! I managed it to work, well almost! The only problem I have is
"Ant location" - I cannot find anything like this anywhere. Which package
should provide it?

 "** GLib-GIO:ERROR:gdbusconnection.c:2270:initable_init: assertion
failed: (connection->initialization_error == NULL) Aborted"

.. this error whereas when I am running qtcreator as normal user then
I am getting this error:

Hi,

Sorry for spamming this mailing list today but I finally get it working! I
just was angry so I made the whole android-ndk chmoded 777 :3. After that I
had problem with stupid ant package which was broken under arch linux. Now
it's working and my application is already done and debugging! I love you
people :D!

Thank You,
Mazur

My congratulations!

Will test it on a number of devices as soon as time permits (this week
is going to be hard).

Best regards,
Sergey A.Galin

my congratulations to your vision and endurance to stem this amazing
project. I am impressed of how you managed to create this complete
solution for development and deployment of Qt apps for the (now) most
popular mobile platform. Kudos to the contributers, too!
I am so happy to see QML applications running on my Android based
media player. With Necessitas&Ministro, you made me an Android
developer although I do not have any clue about Android development.

- Current troll with painful Qt-to-mobile-platform-porting experience

Thank you very much Sergey.

Please let me know if you find something wrong.
I deployed to Android Market a qt demo (Animatedtiles) please use that
application to test Ministro on any device (starting with
android-4(1.6) ending with android-10 (2.3.3), be aware honeycomb is
not yet supported, it should be based on android-9 but I didn't had
enough time to test it).

Cheers,
BogDan.
