Answer 1

Finally I got my solution to get Card Information using CardInputWidget code. Here is how I did it:

if(mCardInputWidget.getCard()!=null){
   String cvv= mCardInputWidget.getCard().getCVC();
   int exp= mCardInputWidget.getCard().getExpMonth();
   int exp_year= mCardInputWidget.getCard().getExpYear();
   String card_num= mCardInputWidget.getCard().getNumber();

   card = new Card(card_num, exp, exp_year, cvv);
}
