Here is my String:

&username=john&password=12345&email=john@go.com

What is the best and most efficient way to break this down into key/value strings so that they can be added as params. Here’s a mock example of what I need:

for (set in array)
{
   params.add(new BasicNameValuePair(set.key, set.value));
}

    Do this:

    String all = "&username=john&password=12345&email=john@go.com";
//Split across all instances of the 'and' symbol
String[] keyValueConcat = all.split("&");
Map<String, String> kvPairs = new HashMap<String, String>();
for (String concat : keyValueConcat) {
    if (concat.contains("=") {
        //For any string in the split that contains an equals sign
        //Split over the equals sign and add to the map
        String[] keyValueSplit = concat.split("=", 2);
        kvPairs.put(keyValueSplit[0], keyValueSplit[1];
    }
}

    And the map kvPairs should contain what you need.
