Kastri cross-platform library

[Michael W. S. 0]

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...
Compiling BiometricDemoD11.dproj (Release, Android64)

There are no such instructions in the readme for that demo project. Doing so is what has caused your problem, as it has re-enabled the jars that need to be disabled. Please re-load the original version of the demo project (BiometricD11)

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.

You mean Delphi 11.1? Delphi 11.2 is yet to be released. I just checked on my Android 9 device - it appears there is an issue. I'll repost again after I've found a solution.

Because it needs to be added to Android 32-bit only. It will apply to both.

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.

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.

There was a "quick fix", however my preference is for something long-term, which I happen to be working on right now. You could try adding this jar to the Android Libraries in the project, however bear in mind the app may still fail depending on what other resources Delphi might deploy.

[Michael W. S. 0]

Thanks, Dave. 

 

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

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.

You can be a guinea pig for this potential fix: 🙂

Please read the readme for details.

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. 🙂

Well, that's the aim. It's one of either stick with the batch files (which is complicated to use), create a completely external tool (less complicated), or include it in an expert such as Codex (hopefully fairly simple to use). The aim is also to have the process generic so that it can be applied to other projects when needed. There's a link to a Quality Portal report in the readme which is essentially asking for the process to be included in Delphi itself.
