Get resources from xml array in android

Question

I have an array in xml file:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <array name="sounds_array">
        <item>R.raw.fart</item>
        <item>R.raw.beep33</item>
    </array>
</resources>

I want to create a media player to play these sounds from my raw folder.

mSoundsArray = mContext.getResources().obtainTypedArray(R.array.sounds_array);


mediaPlayer = MediaPlayer.create(mContext, mSoundsArray.getResourceId(0, -1));
                mediaPlayer.start();

but istead of expected result I got an this error:

Caused by: android.content.res.Resources$NotFoundException: Resource ID #0xffffffff

any idea how can I get resourceId from this array?

This is how i did the same sounds thing :

 Resources res = getResources();
        final TypedArray sounds = res.obtainTypedArray(R.array.sounds_array);
        int[] resIds = new int[sounds.length()];
        for (int i = 0; i < sounds.length(); i++) {
            resIds[i] = sounds.getResourceId(i, -1);
        }
sounds.recycle();

Change :

 <array name="sounds_array">
    <item>R.raw.fart</item>
    <item>R.raw.beep33</item>
</array>

To

<string-array name="select_sounds">       
   <item>@raw/fart</item>
   <item>@raw/beep33</item>
</string-array>

I get two elements -1 in resIds. I should add .mp3 to every <item>R.raw.beep33</item> ?

I am not able to access items in raw folder using <item>@raw/fart</item>. any idea why is that?
