Thanks, Dave!

Hi Dave, thanks for the reply. Need to digest this a bit... it looks quite complicated. 🙂 I hope the final version will be simpler to deploy. 🙂

Just wondering whether there's a possibility of the fingerprint feature in Android 9 for Delphi 11 working any time soon. Are there any current versions of Android confirmed working with Delphi 11? If so, I may try to get a phone with that version, so that I can continue testing.

Thanks, Dave. you are right... it still crashes in Android 9 with the new .jar file. Looking forward to the fix. 🙂

hi Dave, thanks much for the link. didn't realise there were quite a lot of changes required to configure D11 for biometric. just wondering if there is a quick fix for biometric on Android 9 using latest D11.x ... I'm surprised nobody tried this configuration for the past months and found that it crashed the app.

yes, 11.1 the latest patch. Thanks for checking this out on Android 9. Look forward to the fix. When I try to run the biometric module from my own project (not the demo), I get a "Java type JBiometricManager could not be found" error. thanks.

Thanks, Dave! https://github.com/DelphiWorlds/HowTo/tree/main/Solutions/AndroidLibraries I mis-read the linkonly meant for projects created in Delphi 10.4, so I need not do anything if opening BiometricDemoD11.dproj I'm using Delphi 11.2. Note 8, Android 9 (android security patch level 1 april 2021) Used back the original demo files, and now the project compiles and loads to Android phone. When I click the "fingerprint image" in the app in Android 9, the app closes. I checked Permissions. "Use Biometric" is enabled. Is there a known issue with Delphi 11.2 and Android 9? I tried adding dw-biometric-2.0.0.jar in right-click Project, Android64-Library but it does not add for some reason. Appreciate for any advice.

I'm trying out the biometric demo in Kastri project. I followed the instructions in the readme to a) right-click in Library, Revert System Files to Default b) project-clean, project-build But I'm getting multiple errors. I'm using Java version 8. It has no issues with running other Android64 projects, only this biometric one. Checking project dependencies...
