I need to use the 'registerMediaFile' function from https://qt.gitorious.org/qt/qtmultimedia/source/ecce937a054e4a96597cb13c40d216bddbd45891:src/plugins/android/jar/src/org/qtproject/qt5/android/multimedia/QtMultimediaUtils.java But I don't know how, since it is Java. Can someone provide an example?
