The method that may help you is below which you should put into the @override method

String myUrl = url;
myUrl = myUrl.replace("ad", as);

Then use the new string wherever you want . You can't change the original url :)

The Method replace returns the string value as API DOC says

public String replace (CharSequence target, CharSequence replacement)

Try to do this :

@Override
protected void onStart() {
super.onStart();
Intent intent = getIntent();
Uri data = intent.getData();
String mString;
  //want to check contains in data and if contains i want to replace it
if(data.toString().contains("ad")){
    mString = data.toString().replace("ad", "xyz");
}

try {

    webView.loadUrl(mString);
}
catch (Exception e){
    e.printStackTrace();
}
}
