解决方法：禁止Cookie处理

org.apache.commons.httpclient.methods.DeleteMethod

org.apache.commons.httpclient.methods.GetMethod

org.apache.commons.httpclient.methods.PostMethod;

method.getParams().setCookiePolicy(CookiePolicy.IGNORE_COOKIES);

method.addRequestHeader("Connection", "close");

对于本地格式化时区的工具类做如下处理，缓存时区格式，避免每次都出现加载过慢

private static Map formatMap = new HashMap();

/**

* 解决 Android时区加载过慢的问题 Loaded time zone names for en_US in 1904ms.

* @see http://blog.163.com/dmg_123456/blog/static/567050632011515113530636/

* @param date

* @param format

* @return

*/

public static String getGMTFromDate(Date date, String format){

if (date == null) {

return null;

}

SimpleDateFormat sdf = formatMap.get(format);

if (null == sdf) {

sdf = new SimpleDateFormat(format, Locale.ENGLISH);

sdf.setTimeZone(TimeZone.getTimeZone("GMT"));

formatMap.put(format, sdf);

}

synchronized (sdf) {

// SimpleDateFormat is not thread safe

return sdf.format(date);

}

}

public static String getStringTypeDate(Date createdAt) {

//SimpleDateFormat dateFormat = new SimpleDateFormat(

//"EEE MMM dd HH:mm:ss z yyyy", Locale.ENGLISH);

//String date=null;

// date = dateFormat.format(createdAt)

//.replace("GMT+08:00", "+0800");

//date = dateFormat.format(createdAt)

//.replace("CST (China)", "+0800");

//return date;

return getGMTFromDate(createdAt, "EEE MMM dd HH:mm:ss z yyyy");

}

public static String getStringTypeDatePrivate(Date createdAt) {

//SimpleDateFormat dateFormat = new SimpleDateFormat(

//"EEE MMM dd HH:mm:ss.SSS z yyyy", Locale.ENGLISH);

//String date=null;

// date = dateFormat.format(createdAt)

//.replace("GMT+08:00", "+0800");

//date = dateFormat.format(createdAt)

//.replace("CST (China)", "+0800");

//return date;

return getGMTFromDate(createdAt, "EEE MMM dd HH:mm:ss.SSS z yyyy");

}
