Getting duration of music file in android



  • Hi. I want to get duration of a music sound on android.
    I connected a slot to durationChanged signal of QMediaPlayer but it shows the following error in android

    W/dalvikvm(32228): No implementation found for native Lorg/qtproject/qt5/android/multimedia/QtAndroidMediaPlayer;.onStateChangedNative (IJ)V
    

    my code:

        player = new QMediaPlayer(this);
        player->setMedia(QMediaContent(QUrl(media_file_name)));
        connect(player, &QMediaPlayer::durationChanged, [=](qint64 duration){
            qDebug() << "Duration:" << duration;
            media_duration = duration;
        });
        connect(player, &QMediaPlayer::stateChanged, [=](QMediaPlayer::State newState){
            if(newState == QMediaPlayer::PlayingState)
                setTilesEnabled(false);
            else
                setTilesEnabled(true);
        });
    

    I commented second connect, but does not work either.

    Qt 5.6.0 on Arch linux
    Thanks
