Android Deployment Fatal signal 11 (SIGSEGV) at 0xdeadbaad, can't instantiate class org.qtproject.qt5.android.multimedia.QtAndroidMediaPlayer;



  • I have in my project file included

    QT += multimedia multimediawidgets

    but it appears that the libraries have no copied over? or something?
    I am trying this on the desktop build it works fine.

    Has anyone seen this error ? I searched for

    W/System.err(18641): java.lang.InstantiationException: can't instantiate class org.qtproject.qt5.android.multimedia.QtAndroidMediaPlayer; no empty constructor

    and found nothing helpful but adding <item>Qt5MultimediaQuick_p</item> to libs which did not at all make a change.

    I am guessing multimedia doesn't actually work on android ?

  • Okay the issue was that multimedia stuff basically is not available for android.
