The version 2.0.0070 works correctly.

hi @fondesa , we changed how we import TensorFlow Lite in version 2.0.0071. Can you please add an explicit dependency to one of the following depending on your use case?

  1. implementation 'com.getbouncer:tensorflow-lite:2.0.0072' if you're not using TFLite anywhere else in your app
  2. implementation 'com.getbouncer:tensorflow-lite-arm-only:2.0.0072' if you're not using TFLite anywhere else in your app and you only support ARM architectures
  3. implementation 'com.tensorflow:tensorflow-lite:2.4.0' if you are using TFLite elsewhere in your app

For more details, we updated our documentation for release 2.0.0071. Please see https://docs.getbouncer.com/bouncer-scan/credit-card-ocr/android-integration-guide#installation

Sorry, I had read only the changelog and not the documentation before updating it. Adding the TensortFlow Lite dependency fixes the problem, thanks.

This should have been more clear in the changelog. I'll make sure to note larger changes like this there going forward. Thanks for pointing that out!
