我想实现一个应用程序来获取Android默认浏览器历史记录并将浏览器历史记录保存到xml文件.但浏览器历史记录不会将某些设备保存到xml文件中.

我已经实现了我的应用程序以获取浏览器历史信息以保存到xml文件,如下所示:

private void browserHistoryDOM() {
    try{
        File newxmlfile = new File("/sdcard/Xmlfiles/briwserHistory.xml");
        newxmlfile.createNewFile();
        DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance();
        DocumentBuilder documentBuilder = documentBuilderFactory.newDocumentBuilder();
        Document document = documentBuilder.newDocument();
        Element rootElement = document.createElement("root");
        document.appendChild(rootElement);

        Cursor mCur = managedQuery(Browser.BOOKMARKS_URI,Browser.HISTORY_PROJECTION, null, null, null);
        mCur.moveToFirst();

        if (mCur.moveToFirst() && mCur.getCount() > 0) {
            while (mCur.isAfterLast() == false) {
                Element em = document.createElement("bookmarkIdx");
                em.appendChild(document.createTextNode(mCur.getString(Browser.HISTORY_PROJECTION_BOOKMARK_INDEX)));
                rootElement.appendChild(em);

                long callDate = Long.parseLong(mCur.getString(Browser.HISTORY_PROJECTION_DATE_INDEX));
                SimpleDateFormat datePattern = new SimpleDateFormat ("dd-MM-yyyy/h:m:s:a");
                datePattern.setTimeZone(TimeZone.getTimeZone("GMT"));
                String date_str = datePattern.format(new Date(callDate));

                Element em1 = document.createElement("dateIdx");
                em1.appendChild(document.createTextNode(date_str));
                rootElement.appendChild(em1);

                Element em2 …
