Answer 1

Assuming that u have got it as String following code will print the key value pair from the string

String x ="addedon=2019-11-21+17%3A06%3A42&productinfo=FINE&firstname=Creataum+Test+User&";
    String pair[] = x.split("&");
    Log.e("pairs", Arrays.asList(pair).toString());
    for (int i=0;i<pair.length;i++){
        String key[] = pair[i].split("=");
        Log.e("pair:","key= "+ key[0]+" value= "+key[1]);
    }

Answer 2

This looks like a String with mixture of URL encoding (like %3A for :) and HTML characters (like & for &).

I believe you can try decoding it and then split data like say by & to get data for each key and then further split by = to get value for that key.

For URL decoding you can try like

String decoded = java.net.URLDecoder.decode(url, "UTF-8");

You can simply use String replaceAll() function to create the json.

str= str.replaceAll("=", "\"");
str= str.replaceAll("&", "\",\"");
str= "{\""+ str+ "\"}";

Answer 4

It seems the string is both URL encoded (the %3A) and JSON encoded (the &).

You have to decode the string and then split by '&' and then split each pair to key and value by '='.

You can see here how to JSON decode: Decoding JSON String in Java

URL decoding can be done with Java's URLDecoder class: https://docs.oracle.com/javase/7/docs/api/java/net/URLDecoder.html

For this example I'll just assume the only encoded characters are %3A and &.

String payumoney = "addedon=2019-11-21+17%3A06%3A42&productinfo=FINE&firstname=Creataum+Test+User&";

// String decoding.
payumoney = payumoney.replaceAll("%3A", "-");
payumoney = payumoney.replaceAll("&", "&");

HashMap<String, String> params = new HashMap<String, String>();
String[] pairs = payumoney.split("&");
for (String pair : pairs) {
    String[] keyValue = pair.split("=");
    params.put(keyValue[0], keyValue[1]);
}
