fingerprint-reader-daemon's Issues

Issue convert toImage

Hi! Thanks for share this project, I follow the steps and everything was ok, my device its a NitGen and I have been able to capture the fingerprint but it doesn´t returns the base64-enconded image, I debugged the code and realized that the error comes from this line :

"final Image imageFinger = subject.getFingers().get(0).getImage().toImage();"

Specifically in the toImage() method, it throws the next error : "java.lang.NoSuchMethodError: com.sun.jna.Native.getDirectByteBuffer(JJ)Ljava/nio/ByteBuffer;"

I dont know what could be happen, any idea?

Thank you!

If your app fails, look into this

Apparently, cloning the project and following the instructions is not enough, this happens on Linux/Windows, gradle run throws this error:

> Task :bio-utils:compileJava FAILEDpe

FAILURE: Build failed with an exception.

Apparently there are missing files that we need to grab from the official SDK, saldy, I don't remember what exactly are those.
