Wordnet with Android

Question

I wanted to find some way to integrate wordnet database into android app and accessing it directly

My code

@Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.dictionary_test);

            URL url=null;
            IDictionary dict=null;
            AssetManager assetManager = getAssets();
            try {

            String path = "file:///android_asset/dict/";<----problem probabaly

            url = new URL("file", null, path);
            //construct the Dictionary object and open it
            dict = new Dictionary(url);
            dict.open();
            }
            catch (Exception e){
                e.printStackTrace();}

            // look up first sense of the word "dog "
            IIndexWord idxWord = dict.getIndexWord ("dog", POS.NOUN );
            IWordID wordID = idxWord.getWordIDs().get(0) ;
            IWord word = dict.getWord (wordID);
//            System.out.println("Id = " + wordID);
//            System.out.println(" Lemma = " + word.getLemma());
//            System.out.println(" Gloss = " + word.getSynset().getGloss());
i used toast for above printlns
        }
