• [ADDED] Introduces "configureRetryPolicy()" in the payment builder to configure the retry policy when the result of a transaction can not be retrieved at the end of a transaction. (see dedicated section in README here for more)
  • Both pollingInterval and maxWaitingTime should be provided in milliseconds.
  • If disableBackButton is set to true, the Android device's back button will be disabled while the retry screen is shown.
  • If maxWaitingTime elapses without a response, SumUpAPI.ResultCode.ERROR_UNKNOWN_TRANSACTION_STATUS will be returned.
  • If disableBackButton is set to false, pressing the back button while the retry screen is displayed will also return SumUpAPI.ResultCode.ERROR_UNKNOWN_TRANSACTION_STATUS.
  • If pollingInterval is greater than maxWaitingTime, the value of maxWaitingTime will be adjusted to match pollingInterval.
  • If either pollingInterval or maxWaitingTime is passed as a negative value, it will default to 0.
  • If configureRetryPolicy() is not called, the SDK will default to returning the SumUpAPI.ResultCode.ERROR_TRANSACTION_FAILED error code, and default values will be used while trying to get the status of the transaction.
  • Default values are 2000 ms for the pollingInterval and 60000 ms for the maxWaitingTime.
