New features

• - Added the new APIs, D1PayConfigParams.setTransactionRetryLimit and D1PayConfigParams.setTransactionRetryTimeout, for D1 Pay - Payment setting. The new D1PayConfigParams.setTransactionRetryLimit API is used to configure the maximum number of retries for a contactless payment transaction performed by a POS terminal if the connection is interrupted. The D1PayConfigParams.setTransactionRetryTimeout API is used to configure the time (in seconds) to wait for a transaction retry by a POS terminal before returning an error. - Supports Card Digitization without push notification.

  As the digitization process no longer requires a push notification, the following APIs are no longer necessary and are deprecated:

  • setPollingIntervalForDigitization

  • setPollingEndTimeForDigitization

  Thales integrator relies on the onSuccess callback of AddDigitalCard() API to complete the digitization process.

• Supports 16 KB page sizes to comply with Google Play compatibility requirement. For application to comply with this requirement, it is required to update JNA dependency to version 5.17 or later, and AGP version to 8.5.1 or later.

• The third-party Google Tap and Pay library that was previously integrated within D1 SDK has been obfuscated. As a result, integrators can no longer access the Tap and Pay library directly through D1 SDK. If your application requires access to the Tap and Pay API, you will need to include your own copy of the library within your implementation.
