How to set audio equalizer in android

I am creating a media player in which you need to set the equalizer effect using "seek Baar" as "Bass","terrible","Rock","Pop","Medium" .. I have a link in which some are used for this NDK libraries .. is there any java library for doing this and please explain what would be the logic for this. I am stuck here for 2 days. Any help would be appreciated ...

  @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.equalizertab); f } } else { try { ((GlobalState) getApplicationContext()) .resetEQ(); } catch (RemoteException re) { // TODO: } } } });

Quit the game below:
