public class DatabaseHelper extends OrmLitesqliteOpenHelper {
        private static final String DATABASE_NAME = "database.db";
        private static final String DATABASE_PATH = "/data/data/"+BuildConfig.APPLICATION_ID+"/databases/";

     public DatabaseHelper(Context context) {
        super(context,DATABASE_NAME,null,DATABASE_VERSION);
        copyFromAssets(context);
    }

      private void copyFromAssets(Context context) {
        boolean dbexist = checkdatabase();
        if (!dbexist) {
            File dir = new File(DATABASE_PATH);
                dir.mkdirs();
                InputStream myinput = context.getAssets().open(DATABASE_NAME);
                String outfilename = DATABASE_PATH + DATABASE_NAME;
                Log.i(DatabaseHelper.class.getName(),"DB Path : " + outfilename);
                OutputStream myoutput = new FileOutputStream(outfilename);
                byte[] buffer = new byte[1024];
                int length;
                while ((length = myinput.read(buffer)) > 0) {
                    myoutput.write(buffer,length);
                }
                myoutput.flush();
                myoutput.close();
                myinput.close();
            }
    }
    }

得到Dao我用这个：

public Dao<AnyItem,Integer> getDaoAnyItem() throws sqlException {
        if (daoAnyItem == null) {
            daoAnyItem = getDao(AnyItem.class);
        }
        return daoAnyItem;
    }

但是如何获取Dao如果我的DB将被密码保护？
