    Here is what I did to load multiple resources with a single MediaPlayer:

    /**
     * Play a sample with the Android MediaPLayer.
     *
     * @param resid Resource ID if the sample to play.
     */
    private void playSample(int resid)
    {
        AssetFileDescriptor afd = context.getResources().openRawResourceFd(resid);
    
        try
        {   
            mediaPlayer.reset();
            mediaPlayer.setDataSource(afd.getFileDescriptor(), afd.getStartOffset(), afd.getDeclaredLength());
            mediaPlayer.prepare();
            mediaPlayer.start();
            afd.close();
        }
        catch (IllegalArgumentException e)
        {
            Log.e(TAG, "Unable to play audio queue do to exception: " + e.getMessage(), e);
        }
        catch (IllegalStateException e)
        {
            Log.e(TAG, "Unable to play audio queue do to exception: " + e.getMessage(), e);
        }
        catch (IOException e)
        {
            Log.e(TAG, "Unable to play audio queue do to exception: " + e.getMessage(), e);
        }
    

    mediaPlay is a member variable that get created and released at other points in the class. This may not be the best way (I am new to Android myself), but it seems to work. Just note that the code will probably fall trough to the bottom of the method before the mediaPlayer is done playing. If you need to play a series of resources, you will still need to handle this case.
