Method

voidaddParameter(Map> map, String pair)
add Parameter 
if (pair == null || pair.length() == 0) {
    return;
int equalAt = pair.indexOf('=');
String name;
String value;
if (equalAt > -1) {
    name = decodeUri(pair.substring(0, equalAt));
...
Stringcanonicalize(final SortedMap sortedParamMap)
Canonicalize the query string. 
if (sortedParamMap == null || sortedParamMap.isEmpty()) {
    return "";
final StringBuilder sb = new StringBuilder(100);
for (Map.Entry<String, String> pair : sortedParamMap.entrySet()) {
    final String key = pair.getKey().toLowerCase();
    if (IRRELEVANT_PARAMETERS.contains(key) || key.startsWith("utm_")) {
        continue;
...
Stringcanonicalize(final SortedMap sortedParamMap)
Canonicalize the query string. 
if (sortedParamMap == null || sortedParamMap.isEmpty()) {
    return "";

StringconvertHttpParameters(Map parameters)
Useful method to convert a map of key,value pairs to a String to be used as part of a GET or POST content. 
Set<String> keySet = parameters.keySet();
StringBuilder convertedParameters = new StringBuilder();
for (String name : keySet) {
    convertedParameters.append(encode(name, defaultEncoding));

StringconvertToDataString(Map data)
convert To Data String 
StringBuilder builder = new StringBuilder();
for (Map.Entry entry : data.entrySet()) {
    builder.append(URLEncoder.encode(entry.getKey().toString(), "UTF-8")).append("=")
            .append(URLEncoder.encode(entry.getValue().toString(), "UTF-8")).append("&");
String result = builder.toString();
return result.length() > 0 ? result.substring(0, result.length() - 1) : "";
StringconvertToParameterString(Map parameterMap)
convert To Parameter String 
StringBuilder returnValue = new StringBuilder();
if (parameterMap != null) {
    try {
        for (Entry<String, Object> entry : parameterMap.entrySet()) {
            if (returnValue.length() > 0)
                returnValue.append("&");
            returnValue.append(URLEncoder.encode(entry.getKey(), "UTF-8"));
            returnValue.append("=");
...
MapextractParameters(String parameterString)
extract Parameters 
Map<String, String> params = new HashMap<String, String>();
if (parameterString != null) {
    String[] paramPairs = parameterString.split("&");
    for (String pair : paramPairs) {
        String[] keyValue = pair.split("=");
        if (keyValue.length == 2) {
            params.put(keyValue[0], decode(keyValue[1]));
return params;
Stringformat(final Map> parameters, final String encoding)
Returns a String that is suitable for use as an application/x-www-form-urlencoded list of parameters in an HTTP PUT or HTTP POST. 
final StringBuilder result = new StringBuilder();
for (Map.Entry<String, Set<String>> parameter : parameters.entrySet()) {
    final String encodedName = encode(parameter.getKey(), encoding);
    final Set<String> values = parameter.getValue();
    if (values == null || values.size() == 0) {
        result.append(encodedName);
        result.append(NAME_VALUE_SEPARATOR);
        result.append("");
...
Stringformat(Map parameters, final String encoding)
format 
final StringBuilder result = new StringBuilder();
for (String key : parameters.keySet()) {
    final String encodedKey = URLEncoder.encode(key, (encoding != null ? encoding : DEFAULT_ENCODING));
    final String value = parameters.get(key);
    final String encodedValue;
    if (value != null) {
        encodedValue = URLEncoder.encode(value, encoding != null ? encoding : DEFAULT_ENCODING);
    } else {
