Here is the code with prepare:

Button button1 = (Button) findViewById(R.id.button1);
        FilmSound = MediaPlayer.create(getApplicationContext(),
                R.raw.animalkingdom);
        button1.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                try {
                    FilmSound.prepare();
                } catch (IllegalStateException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                } catch (IOException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
                if (FilmSound.isPlaying()) {
                    FilmSound.stop();
                    FilmSound.reset();

                    FilmSound = MediaPlayer.create(getApplicationContext(),
                            R.raw.animalkingdom);
                    FilmSound.start();
                } else {
                    FilmSound = MediaPlayer.create(getApplicationContext(),
                            R.raw.animalkingdom);
                    FilmSound.start();
                }
            }
        });

I just had a similar issue. I solved it by simply adding the following to your manifest file:

 <uses-permission android:name="android.permission.INTERNET" />

Prior to ICS no Internet Permission was required.

After you create the MediaPlayer, try preparing it:

FilmSound.prepare();

Check this question out: Android -- Can't play any videos (mp4/mov/3gp/etc.)?

Have you tried playing a file in a different format? Maybe your sound requires some codec that Android doesn't have, so the prepare() fails.

Remove the create() method outside of the onClickListener. Right now when you start the app it will create 10 instances of FilmSound since the code is outside of onClickListener, then when you click a button it will create the 11th instance of FilmSound. Likely this is running out of memory below Android 2.2. You don't need to prepare after using the create() method, it will prepare after create the first time.

Also, I'm pretty sure isPlaying() can throw exceptions.

if (FilmSound != null) {
try {
        if (FilmSound.isPlaying()) { 
             FilmSound.release(); 
             FilmSound = null;
        }
    } catch(Exception e) {FilmSound= new MediaPlayer(); }};

if (FilmSound == null) {
    FilmSound= new MediaPlayer(); 
}
    FilmSound = MediaPlayer.create(this, clip);
    FilmSound.start();
    FilmSound.setOnCompletionListener(this);
