Necessitas android alpha 3 is live :) next billion devices is here :)





  • Nice, and Yea, and hope it would be "Officially" approved,one day!



  • Here the full post of BogDan on android-qt mailing list (Perhaps someone can add this to Qt Blog ?)

    Hello everybody,

    I know we are a little late to the party, but we'd like to say:
    Happy birthday KDE !!!
    Of course we couldn't come with empty hand, so we come with a gift:
    the Necessitas alpha3 release !

    Necessitas alpha3 release should be the last but one release, before
    we'll ship first beta version. Why the beta release is so important
    and why is delayed that much? The beta release will GUARANTEE the
    API/ABI compatibility, meaning that an application which uses that
    version will run without any change, on any further releases! It
    also means you can target a billion devices using Qt, much sooner than
    you expected Of course if the situation will require we reserve the
    right to release additionally alpha releases, because going to beta is
    a great responsibility we can't afford to screw it up. IF everything
    goes right, we want to release the first beta SDK until the end of
    this year !

    Also don't forget that this release is focused mostly on features
    completeness, the next releases will be focused mostly on stability,
    so if your issue(s) is/are not yet fixed, please have a little more
    patience (and understanding ).

    Most of all, we need your help to make it happen, so please:

    Alpha 3 release brings you lots of exciting features, I'd like to talk
    a little bit about two of them:

    • OpenGL this is probably the most expected and exciting feature of
      this release. Yes, is here ! We tried (and succeed) to give you a
      seamless OpenGL support, even if we have different platform plugins to
      handle raster and OpenGL drawings, you don't need to worry about it,
      if your application will require OpenGL, we'll choose automatically
      the right plugin for your application.
    • Java redesign and Ministro II, this is a huge step forward for this
      project, this work will give us freedom to change the platform plugin
      as we wish without breaking any existing application. How it works ?
      Your applications doesn't know anything about qt libs, platform
      plugins and stuff like that, it only knows that it needs to connect to
      Ministro service, pass some parameters to it and to wait for its
      response, when the response comes it will have a list with .jar files
      which your applications needs to load them at runtime and to
      instantiate the startup class, this class will load Qt libs and your
      application. Basically the old java part was moved to these .jar files
      which will be provided by Ministro, Ministro will take care that
      the .jar files and qt platform libs will always be compatible.

    BE AWARE !!! Because your application needs other java sources, please
    make sure you are removing the old ones (please remove android folder
    from any existing project)!!!

    I'd like to highlight the most important features:

    Qt framework:

    • OpenGL Support
    • Java part redesign
    • QAtomic implementation
    • Seamless Android assets support
    • Sync with upstream Qt 4.8.0-rc1

    QtCreator:

    • Prepare the package for android market publishing
    • Sync with QtCreator 2.3.1

    QtWebkit:

    • Sync with QtWebkit 2.2.0
    • It seems that the massive memory leak form 2.1.x was fixed.

    QtMobility:

    • Sync with Qt framework changes.

    Necessitas SDK:

    • Linaro toolchain based on gcc 4.6.x (it is experimental)
    • Android-4+ (armv5 & raster only) SDK
    • Android-5+ (armv5&armv7, raster&OpenGl) SDKs

    Minitro:

    • Can provide specific CPU extensions libraries, this feature allows
      us to provide not only platform specific libs (armv5, armv6, armv7,
      x86, etc.) but also libs for specific CPU extensions, e.g. if your CPU
      supports VFP but the platform not (is the case of armv5) Ministro can
      download libs for armv5 WITH VFP flags turn on, also if automatic
      vectorization [1] will improve the speed will ship Qt libs compiled
      completely with NEON, where devices CPU supports NEON instructions,
      currently Qt detects at runtime if your CPU supports NEON and it uses
      that extension only in a few drawing functions.
    • Sync with Qt framework changes

    Known issues:

    Linux:

    • None till this date.

    Mac:

    • Sadly we found a show stopper just before release and we delayed
      the release a few days until we'll figure out what is wrong. We'll
      come with a separate announcement when this platform will be ready.

    Windows:

    • You must select manually the application (projects->run->package
      configurations->Run: <select the application >) Open [2] and search
      for "Application Tab". A fix will be available next week.
    • You can't create AVDs from within QtCreator.

    I want to personally thank to all who answered other people
    questions, to all how reported errors and made suggestions !
