mp3 via QMediaPlayer on Androis based XPeria Z2

[Flaming Moe]

Hello there,

i try to play a mp3 on an Android based XPeria Z2.
Code is very simple

#include "mainwindow.h"
#include <QApplication>
#include <QMediaPlayer>

int main(int argc, char *argv[])
{
QApplication a(argc, argv);
MainWindow w;

QMediaPlayer* player = new QMediaPlayer;
// ...
//player->setMedia(QUrl::fromLocalFile("C:/WithASpirit.mp3"));
player->setMedia(QUrl::fromLocalFile("Music/Adiemus.mp3"));
player->setVolume(100);
player->play();

w.show();

return a.exec();

}

On Desktop Win7 PC is works fine.
When deploying it to the Smartphone i get a

E/MediaPlayer-JNI(11261): QCMediaPlayer mediaplayer NOT present
D/Qt MediaPlayer(11261): null

note. I guess it relates to the documentation saying
"The compressed audio formats supported does depend on the operating system environment, and also what media plugins the user may have installed."

I´m not deep enough in the material to figure out my self what to do.
Has someone a hint?

best regards!!
