It's public, right :)

You can call bindService(Intent) method. Tale a look at ApiDemos, the class LocalServiceBinding.

In the callback method onServiceConnected, you can see:

    public void onServiceConnected(ComponentName className, IBinder service) {
        // This is called when the connection with the service has been
        // established, giving us the service object we can use to
        // interact with the service.  Because we have bound to a explicit
        // service that we know is running in our own process, we can
        // cast its IBinder to a concrete class and directly access it.
        mBoundService = ((LocalService.LocalBinder)service).getService();

        // Tell the user about this for our demo.
        Toast.makeText(LocalServiceBinding.this, R.string.local_service_connected,
                Toast.LENGTH_SHORT).show();
    }

Now, use the service object (mBoundService) to call the method.

That's all :)
