I want to test paypal in my android app to do that I have followed all steps of docs of paypal
the sdk example works well in sandbox envirement with credit card payment
but when I test payment with paypal,I canno't arrive to log in
always, I have this message
login failed : invalid login information please try again
knowing that I have entered the right email and passwod and not the account to which the payment will be send
but only one thing, the paypal account is only for testing and not linked to a credit card
do you have any idea
