Can't make charge with stripe in android Fire base

[Saboor8802]

Hello to all! Hope you are fine. I am developing an e-commerce android app and integrating Stripe payment gateway in it and using Google Fire base as real time database. I browsed the official website of stripe and took the source code from there. I used my test key from there. I successfully generated Stripe Token and saved it on my server (i-e Fire base). But I am unable to make an actual charge by using that token. That means no transaction shows on my stripe account. I am pasting my code, guide me what should i do to create/make charge?

Card cardToSave = cardInputWidget.getCard();
if (cardToSave == null) {
Toast.makeText(getActivity(),"Invalid Card Data",Toast.LENGTH_LONG).show();
// mErrorDialogHandler.showError("Invalid Card Data");
}
else{

                Stripe stripe = new Stripe(MainActivity.mcont, 
            "pk\_test\_XZFc6CW7wmDMl4WWESxtvWd300ibs1wr85");
                
                      stripe.createToken(
                        cardToSave,
                        new TokenCallback() {
                            public void onSuccess(final Token token) {
                                // Send token to your server
                                customer\_ref = 
                           database.getReference("Customers").child(MainActivity.user.getUid());
                                 final String tokenid = token.getId();


                                          //saving the tokenID on my server(i-e fiebase)

                                        final Map params = new HashMap<>();
                                        params.put("amount", paid);
                                        params.put("currency", "usd");
                                        params.put("description", "Example charge");
                                        params.put("source", tokenid);

                                        HashMap map = new HashMap();
                                        map.put("StripeToken",tokenid);
                                        customer\_ref.updateChildren(map);

                                        try {
                                            // creating charge object
                                            Charge charge = Charge.create(params);
