Xamarin.Android Project | Enrollment | Error on Capture #43

Closed jlinker7 closed 1 year ago

jlinker7 commented 1 year ago

I am integrating the fingerprint reader into a Xamarin.Android project (Android 7.1). I used a bindings project with the jar and the .so files. It works for general scanning, but when I attempt to use the enrollment process when I call the readers Capture method I get the following error.

java.lang.UnsatisfiedLinkError: No implementation found for int com.digitalpersona.uareu.jni.Dpfpdd.DpfpddCaptureExt(

Can you provide any insight into what I am missing? I attempted using the Metadata.xml to transform the method, but am new to that so may have had it wrong if that is what is required (would need a specific example of what to put in there). Thanks!

This repository is for a JavaScript library, not Java SDK.

@jlinker7 We have no any online Java SDK repo or issue tracker, I cannot provide you a link, sorry. You should contact whoever you obtained the Java SDK from, for example HID Global customer support.

This repository is not intended to be a general customer support line.

@a-bronx Thank you, that was much more helpful and informative. My apologies for my smart remark and I do appreciate the follow up.
