Hi @squio thanks for reporting this!

We have looked into this and updated this SDK to 2.1.14 which now supports the Android Scanner SDK version 2.1.11. We expect the issue to be resolved with this, in case you are still getting crashes the error message should be more clear for us to debug and fix. In that case feel free to reopen this issue with the new logs!

On https://custom-ocr.klippa.com/sdk-public/android/scanner#changelog you can find the Android specific CHANGELOG.
