Phonegap + MediaPlayer

Hallo zusammen,

ich möchte den Media Player in meine Phonegap App einbinden, was auch super funktioniert.
Leider bekomme ich es nicht hin, dass auch die Controls dafür angezeigt werden (Play / Pause, Timeline...).

Ich weiß aktuell nicht mehr weiter und habe verschiedene Dinge probiert.
Ich würde mich freuen, wenn ein Erfahrener User mir einen hilfreichen Tipp geben könnte!

Das ist mein Code:
