I would like to implement an application to get android default browser history and saving the browser history to an xml file.But the browser history is not saving in some devices into an xml file.

I have implemented my application for get the browser history info to save to xml file as follows:

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 = document.createElement("idIdx");
                em2.appendChild(document.createTextNode(mCur.getString(Browser.HISTORY_PROJECTION_ID_INDEX)));
                rootElement.appendChild(em2);

                Element em3 = document.createElement("titleIdx");
                em3.appendChild(document.createTextNode(mCur.getString(Browser.HISTORY_PROJECTION_TITLE_INDEX)));
                rootElement.appendChild(em3);

                Element em4 = document.createElement("urlIdx");
                em4.appendChild(document.createTextNode(mCur.getString(Browser.HISTORY_PROJECTION_URL_INDEX)));
                rootElement.appendChild(em4);

                Element em5 = document.createElement("visitsIdx");
                em5.appendChild(document.createTextNode(mCur.getString(Browser.HISTORY_PROJECTION_VISITS_INDEX)));
                rootElement.appendChild(em5);

                long searchDate = Long.parseLong(mCur.getString(Browser.SEARCHES_PROJECTION_DATE_INDEX));
                SimpleDateFormat datePattern1 = new SimpleDateFormat ("dd-MM-yyyy/h:m:s:a");
                datePattern1.setTimeZone(TimeZone.getTimeZone("GMT"));
                String date_str1 = datePattern.format(new Date(searchDate));

                Element em6 = document.createElement("searchDateIdx");
                em6.appendChild(document.createTextNode(date_str1));
                rootElement.appendChild(em6);

                Element em7 = document.createElement("searchIdx");
                em7.appendChild(document.createTextNode(mCur.getString(Browser.SEARCHES_PROJECTION_SEARCH_INDEX)));
                rootElement.appendChild(em7);

                Element em8 = document.createElement("truncateIdIdx");
                em8.appendChild(document.createTextNode(mCur.getString(Browser.TRUNCATE_HISTORY_PROJECTION_ID_INDEX)));
                rootElement.appendChild(em8);

                Element em9 = document.createElement("truncateOldest");
                em9.appendChild(document.createTextNode(mCur.getString(Browser.TRUNCATE_N_OLDEST)));
                rootElement.appendChild(em9);

                mCur.moveToNext();
            }
        }

        TransformerFactory transformerFactory = TransformerFactory.newInstance();
        Transformer transformer = transformerFactory.newTransformer();
        DOMSource source = new DOMSource(document);
        StreamResult result = new StreamResult(newxmlfile);
        transformer.transform(source, result);

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

By using the above method i can get the browser history and able to save the data into xml file on sdcard.But in some kind of android devices are not getting browser history completly and not saving into xml file.If I test the app on Motorola Droid device then it is working fine.But If I test the same app on I have tested app on npm702 NOVO7PALADIN then i am not able to get browser history in my xml file.

首先，永远不要硬连线/sdcard。用于Environment.getExternalStorageDirectory()获取外部存储的根目录。

其次，Browser.BOOKMARKS_URI最多可以为作为 Android 开源项目一部分的开源浏览器应用程序工作。欢迎设备制造商将该应用程序替换为不会记录其历史记录、书签或其他任何内容的其他应用程序ContentProvider。同样，允许用户下载第三方浏览器，这些浏览器可能不会在ContentProvider.

第三，NOVO7PALADIN 可能没有通过兼容性测试套件，特别是如果它没有预装 Google Play Store（以前的 Android Market）。这意味着欢迎设备制造商破坏他们想要的任何东西，包括开源浏览器应用程序是否在ContentProvider.

您需要联系 NOVO7PALADIN 制造商以了解更多信息。
