Can't make payments with PayPal Android SDK


I'm developing a simple food order app for a friend with PayPal payment.

To do this, I've watched a YouTube tutorial ( this https://www.youtube.com/watch?v=ae82zSy4CSM&t=78s ) and I've implemented the code in my app. The problem is that if i see the JSON output file, it's all ok but when I try to pay with my credit card, the money does not arrive on my friend's paypal account and when i go to check the money on my card, it does not actually decrease. If instead I try to pay with the paypal circuit, it refers to the error "incorrect username / password, please try again" when logging in, even though my credentials are correct.

                            Log.d("FuturePaymentExample",authorization.getAuthorizationCode());

                        }
                    }
                }
            }
        }
    }

In the verbose I don't notice any errors attributable to the paypal API. Any suggestions?


Solution

  • I think you're working in sandbox. Thats why you can't play with real money on real accounts.
