SQLite不断扩张

我是黑莓开发和这个网站的新手。现在，我正在开发一个从json服务检索数据的应用程序。在我的应用程序中，我应该将数据解析到数据库中，并将其保存在四个表中。我已经解析了数据，并且成功地创建了数据库并添加了第一个表和第二个表

我现在面临的问题是，我数据库中的第二个表不断扩展。我在sql浏览器中检查了数据库，发现每次单击应用程序图标，它都会再次将700行添加到表中。（例如，700变为1400）

（只有第二张桌子，第一张桌子工作得很好）

先谢谢你

这是我的代码：

public void parseJSONResponceInBB(String jsonInStrFormat)

    try {
        JSONObject json = newJSONObject(jsonInStrFormat);
        JSONArray jArray = json.getJSONArray("tables");

        for (inti = 0; i < jArray.length(); i++) {
            //Iterate through json array
            JSONObject j = jArray.getJSONObject(i);
            if (j.has("Managers")) {
                add(new LabelField("Managers has been added to the database"));

                JSONArray j2 = j.getJSONArray("Managers");

                for (intk = 0; k < j2.length(); ++k) {
                    JSONObject MangersDetails = j2.getJSONObject(k);
