实例代码：

        jsqlite.Database db = new jsqlite.Database();

        try {
            db.open((mContext.getFilesDir().getAbsolutePath() + File.separator + DB_NAME), jsqlite.Constants.SQLITE_OPEN_READONLY);

            Callback cb = new Callback() {
                @Override
                public void columns(String[] coldata) {
                    Log.v(TAG, "Columns: " + Arrays.toString(coldata));
                }

                @Override
                public void types(String[] types) {
                    Log.v(TAG, "Types: " + Arrays.toString(types));
                }

                @Override
                public boolean newrow(String[] rowdata) {
                    Log.v(TAG, "Row: " + Arrays.toString(rowdata));

                    return false;
                }
            };

            String query = "SELECt AsText(GEOMETRY) from Table";
            db.exec(query,  cb);
            db.close();

        } catch (Exception e) {
            e.printStackTrace();
        }
