QSplashScreen doesn't work in Android

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    QPixmap splashpic("qrc:/splash.png");
    QSplashScreen splash(splashpic);
    splash.show();
    a.processEvents();
    MainWindow w(Q_NULLPTR);
    w.show();
    splash.finish(&w);
    return a.exec();
}
