I can't get the mediaplayer working in android studio

I'm trying to get some sound in my app, but I can't get the mediaplayer working! I got some errors like: 

java.lang.NullPointerException: Attempt to invoke virtual method 'void android.media.MediaPlayer.start()' on a null object reference

with the following code:

private MediaPlayer mPlayer;

@Override
protected void onCreate(Bundle savedInstanceState) {
mPlayer = MediaPlayer.create(this, R.raw.NAMEOFSOUND);
}

protected void playBtnClicked(){
    mPlayer.start();
}

It just doesn't work, whatever I do ... Does someone got some tips/Can someone help me out? The ''NAMEOFSOUND'' is a .mp3 file, I don't know if it even matters? Thank you!

SOLVED: I just solved it by coverting the file with a converter. Just changing the name+.mp3 didn't solve it; NullPointerException in Java Android App MediaPlayer , comment of Berty did the trick!

As you can see in the supported Media formats .mav is not supported by android. you should convert it to mp3 or any of the supported file formats
