I have to use the PayPal Android SDK, so I'm trying to modify the sample app. I have an account in https://developer.paypal.com and I created a REST API app: a pair Client ID - Secret was correctly generated. In the sample app code, if I set the configuration to PayPalConfiguration.ENVIRONMENT_NO_NETWORK, I can correctly login before the payment procedure, even if it is a "fake" login. But if I change the configuration to PayPalConfiguration.ENVIRONMENT_SANDBOX, in the authentication login I type email and password of my PayPal Sandobox account (the buyer one, automatically created), it generates an error and the login procedure does not work. The error is:
E/paypal.sdk(5131): request failure with http statusCode:401,exception:org.apache.http.client.HttpResponseException: Unauthorized E/paypal.sdk(5131): request failed with server response:{"error":"invalid_user","error_description":"Invalid user credentials"} E/paypal.sdk(5131): invalid_user
