How to get the value of parameter of chapter and post?

Answer 1

You can use the Uri class in Android to do this; https://developer.android.com/reference/android/net/Uri.html

Uri uri = Uri.parse("http://www.chalklit.in/post.html?chapter=V-Maths-Addition%20&%20Subtraction&post=394"); String server = uri.getAuthority(); String path = uri.getPath(); String protocol = uri.getScheme(); Set<String> args = uri.getQueryParameterNames(); 

Then you can even get a specific element from the query parameters as such;

String chapter = uri.getQueryParameter("chapter");  //will return "V-Maths-Addition "
