Wordnet与Android

Question

我想找到一些方法将wordnet数据库集成到Android应用程序并直接访问它

我的代码

@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
        }

阅读此内容但没有帮助 Access WordNet dict files in Android app

我在这里读到资产文件夹的文件不能超过1 mb，但有些文件超过1 mb，差不多有5或8 mb。 如果是这样 1.如何将应用程序复制所需文件复制到外部位置？

我收到错误

首先使用此数据库 http://wordnetcode.princeton.edu/wn3.1.dict.tar.gz

稍后尝试这个 http://wordnetcode.princeton.edu/3.0/WNdb-3.0.tar.gz

但无法解决错误

所有建议都适用
