Deploy applications for Android



  • Hi,

    I try to deploy applications for Android with QtCreator 2.7.1.
    To do so, first I installed Android SDK (with API level 10 and 11) and Android NDK. Then I compiled Qt 5.1.1 against SDK, NDK and a OpenJDK (AMD 64 because my Linux is 64 bits).

    On QtCreator, I tried to deploy a simple Qt example application and to run it on a physical device connected to my computer.
    But when after deployment, when application is started, it crashes with an error :

    @Starting remote process.D/AndroidRuntime(12230): Shutting down VM

    Strange thing is that it looks for an executable named puzzle, that must be generated by the compilation of the project.
    But when project is compiled, only a libpuzzle.so is generated instead of the executable.

    I use Android API level 10 to deploy application.
    In QtCreator Run Settings, I use the options_ Deploy local Qt libraries_ and Use local Qt libraries.

    I tried other Deploy configurations, but it always crashes on the same error.

    I also correctly informed QtCreator of Android SDK and NDK paths and of JDK location in Android Options.

    Is there something I missed or I did wrong ? Could you please help me to fix this problem ?

    Thanks,

    Jérémie
