@NawnitSen Regex? You could also do it with a 3rd party webserver, but why would you need so powerful for something so simple. — Nick Cardoso, Oct 11 '18 at 10:51
Just split the String with the delimiter `?` and you will get your result. — Kunu, Oct 11 '18 at 10:53

You need to use String.substring()

Try to substring your string from the index of id to length of your string

In this below example i have started substring from index of ? +1 so it will start substring your string from id to length of your string

SAMPLE CODE

    String packageName = "https://play.google.com/store/apps/details?id=com.MoversGames.DinosaurWorldGame";

    String answer = packageName.substring(packageName.indexOf("?")+1, packageName.length() );
    Log.e("ANSWER", answer);

OUTPUT

2018-10-11neel.com.myapplication E/ANSWER: id=com.MoversGames.DinosaurWorldGame

There might be also some more query parameters in your String , so you can also try it like this :

String packageName = "https://play.google.com/store/apps/details?i 
id=com.MoversGames.DinosaurWorldGame&x=y&z=a";

String answer = packageName.substring(packageName.indexOf("id"));
System.out.print("ANSWER", answer);
