Qt + Android + Irrlicht. Need to get android_app*



  • Hi all.
    I've built Irrlicht folowing this guide: http://irrlicht.sourceforge.net/forum/viewtopic.php?f=5&t=49755
    27.HelloWorld_Android example of Irrlicht works nice on my phone.
    But now I try to port project, which uses Irrlicht, to Android with my built Irrlicht lib.
    This lib uses android_app* which it gets from
    void android_main(android_app* app)
    I don't provide it, so my irrlicht widget crashes.

    What is the simplest way to solve it?
    Is there any way to get android_app pointer without android_main or rewriting irrlicht source code?

    edited: I think a main question is "How can I obtain android_app* in Qt?"

    Hi,

    I haven't use Irrlicht but shouldn't you rather try to run Irrlicht in a QWindow/QWidget ?



  • I use QWidget over Irrlicht and it works fine with desktop version of Irrlicht lib.
    The problem is that android irrlicht lib expects android_app* pointer in parameters. android_app* is provided by android_main function. And I see 3 ways to solve it:

    1. obtain android_app* in Qt and provide it in parameters. So the question - how to obtain it?
    2. rewrite some source code of irrlicht android lib, but I think it's wrong way
    3. try to build android lib from desktop irrlich lib source code by ndk-build, but I think it's worse than 2nd way.

    You can also try asking the Irrlicht devs to see if they came across that use case.

    One other source of information is the Android-development mailing list You'll find there Qt's Android port developers/maintainers (this forum is more user oriented)
